The Cooper PowerStor®family of aerogel capacitors offers ultra-low
resistance supercapacitors, unique high-energy storage devices.
Supercapacitors Extend Battery Life
The Cooper PowerStor®A series supercapacitors are available in
values from 0.47F to 4.7F, 2.5V and offer equivalent series resistance
as low as 25mΩ. In remote battery powered applications that have
pulse current loads this low ESR can be utilized to prolong battery
life.
Low cost battery solutions tend to have high ESR and as a result large amounts of stored energy can’t
be used when supplying pulse currents. By combining a supercapacitor in parallel with the battery the
overall ESR is lowered and battery life, typically, increased by 300%. For remote applications such as
utility meters, weather & river level monitoring and hotel door locks this can dramatically reduce
replacement costs.
Offering Environmentally Friendly Alternative to Ni-CD Batteries
The Cooper PowerStor®B series is available in values from 0.22F to 50F,
2.5V and is fully compliant with the EC RoHS directive. For equipment that
is only required for short term use, up to several minutes, and has a local
charger the B series offers a realistic alternative to Ni-CD batteries.
Low equivalent series resistance allows the B series parts to be rapidly charged and discharged
without damage and low leakage current means they can hold their charge for weeks. Unlike batteries
PowerStor®supercapacitors have a very long cycle life, over 500,000 cycles, so they won’t need
replacing and at end of life there are no recycling or disposal issues.
Supercapacitors Provide Last Gasp Power
The Cooper PowerStor®P series is available in values from 0.1F to 1.0F,
5V and is ideal for hold-up and bridging power applications. For telecom
products such ADSL routers a P series supercapacitor can be used to
provide power for a ‘leaving network’ signal after a mains supply failure.
Unlike batteries the P series supercapacitors have a long cycle life, over 500,000 cycles, so they won’t
need replacing. In addition to this they have ESR as low as 0.2 Ohms and small package sizes from
0.75 cm3to 4.7 cm3. All this makes the P series an ideal choice for supporting continued operation
during battery swap-out or for controlled shut down after a mains failure.
Providing Power Management Solutions
In addition to a broad range of standard products Cooper PowerStor®
also offer custom solutions for applications such as automated meter
reading, PCMCIA cards, handheld electronics, data storage systems
and toys.
These products include high integrity capacitor packs that incorporate
active voltage balancing, ultra thin ‘Flat Pack’ devices with low ESR
and optimized cylindrical components that meet specific customer
requirements.

FUSE TECHNOLOGY
This fuse technology guide will discuss basic fuse
operating, application, and selection criteria concepts.
The intended purpose of this section is to aid
designers with the operation and characteristics of
an overcurrent protection device and to assist in
device selection.
Overcurrent fuses serve two main purposes:
a. To protect components, equipment and
people from risk of fire and shock caused
by overcurrents.
b. To isolate sub systems from the main
system once a fault has occurred.
Overcurrents
Overcurrents exist when the normal load for a circuit is
exceeded. It can either be an overload or short circuit
condition.
An overload condition is any current flowing within the
circuit path that is higher than the circuit’s normal full
load current. An overload is typically 2 to 5 times the
magnitude of a circuit’s normal operating current.
A short circuit is an overcurrent condition that leaves
the normal current path and which greatly exceeds the
normal full load current of the circuit by a factor of tens,
hundreds, or thousands. Components and equipment
can be damaged by both types of overcurrents.
Selecting Overcurrent Protection
During normal load conditions, the fuse must carry the
normal operating current of the circuit without nuisance
openings. However, when an overcurrent occurs
the fuse must interrupt the overcurrent and withstand
the voltage across the fuse after internal arcing.
To properly select a fuse the following items must
be considered:
• Voltage rating (ac or dc voltage)
• Current rating
• Normal operating current
• Ambient temperature
• Overload conditions and opening times
• Available short circuit current
• Melting Integral (I2t)
• Pulse and In-rush characteristics
• Characteristics of equipment or components
to be protected
• Physical size and available board space
• Standards requirements
Voltage Ratings
The voltage rating of the fuse must be greater than or
equal to the maximum open circuit voltage. Because
the fuse has such low resistance, the voltage rating
becomes critical only when the fuse is trying to open.
The fuse must be able to open quickly, extinguish the
arc after the fuse element has melted and prevent the
system’s open-circuit voltage from re-striking across
the open fuse element.
Current Ratings
The current rating of a fuse identifies its current-
carrying capacity based on a controlled set of test
conditions. Each fuse is marked with its current rating.
This rating can be identified with a numeric, alpha, or
color code mark. Marking codes can be found in each
product’s data sheet.
Normal Operating Current
The normal operating current of a circuit is the level
of current drawn (in RMS or dc amperes) after it has
been energized and is operating under normal
conditions. An operating current of 80% or less of
rated current is recommended for operation at 25°C
to avoid nuisance openings. For example, a fuse with
a current rating of 1A is usually not recommended in
circuits with normal operating currents of more than
800mA. Further derating is required at elevated
ambient temperatures.

Fuse Technology
Ambient Temperature
Ambient temperature is the temperature of the
air immediately surrounding the fuse and is not
necessarily room temperature. All electrical
characteristics of a fuse are rated and validated at an
ambient temperature of 25°C. Both higher and lower
ambient temperatures will affect the fuse’s opening
and current carrying characteristics. This effect is
demonstrated in temperature re-rating curves. Please
refer to the re-rating curves for individual product
series found in the Engineering Product Specifications
located on the Cooper Electronic Technologies web
site, or contact CET directly for technical assistance.
Overload Conditions and Opening Times
Specific attention must be given to first overload
operating points. For fuses, the first overload point is
usually between 200% to 300% of rated current. 400%
is typically the first overload point for circuit protectors.
Breaking Capacity / Interrupting Rating
A fuse must be able to open the circuit under a short
circuit condition without endangering its surroundings.
The breaking capacity or interrupting rating of a
protective device is the maximum available current, at
rated voltage, that the device can safely open without
rupturing. The breaking capacity or interrupting rating
of a fuse must be equal to or greater than the available
short circuit current of the circuit.
Melting Integral
The melting integral of a fuse, termed melting I2t, is
the thermal energy required to melt a specific fuse
element. The construction, materials, and cross
sectional area of the fuse element will determine this
value. Each fuse series and ampere rating utilize
different materials and element configurations, and
therefore it is necessary to determine the I2t value for
each fuse. Tests to determine the I2t of a fuse are
usually performed with a fault current of at least 10x
the rated current with a time constant of less than 50
microseconds in a DC test circuit. High-speed
oscilloscopes and integral programs are used to
measure very accurate I2t values.
The melting I2t of a fuse is one of the values used to
assist circuit designers when selecting and properly
sizing a fuse in a specific application. It can be
compared to the thermal energy created by transient
surge currents in a circuit.
Surge and Pulse Current Characteristics
Transient surge or pulse currents are used to describe
wave shapes that result from any startup, inrush,
surge, or transient currents in a circuit. The pulse
currents are normal for some applications. It is
therefore important to size the fuse properly to allow
these pulses to pass without nuisance openings or
degradation of the fuse element. The fuse must then
open within the limits specified by UL and CSA if the
overload condition continues. The ability to resist
surges is a function of the fuse design and/or
classification relative to the surge pulse, duration
frequency etc.
Pulse currents can produce thermal energy that may
not be large enough to open the fuse but could
possibly cause element fatigue and decrease the life
of the fuse. To properly size a fuse and determine its
surge withstand capability, the circuit’s pulse energy
should be determined and compared to the time
current curve and I2t rating of the fuse. The fuse’s
melting I2t value must be greater than or equal to the
pulse I2t multiplied by a pulse factor.
The peak current and decay time define the pulse
current characteristic or waveform. Pulses can
generate different waveform shapes, which determines
the formula used to calculate the pulse energy or I2t.
Refer to Table 1 to select the appropriate waveform
and its corresponding pulse I2t calculation.

Fuse Technology
Fuse Surge Withstand Capability
The fuse’s capability to withstand a surge pulse without
causing thermal stress to the fuse element, which may
result in nuisance openings, can be determined once
the circuit’s pulse I2t is calculated. The circuit designer
needs to properly size the fuse so that the fuse’s
melting I2t value is greater than or equal to the pulse I2t
multiplied by a pulse factor Fp(I2tfuse ≥I2tpulse xF
p).
The pulse factor is dependent on the construction
of the fuse element. A wire-in-air constructed fuse
element (ferrule fuses, 6125 and 1025 series for
example) will be affected by the number and frequency
of surge pulses the fuse is subjected to over the
lifetime of the device. This construction design utilizes
low-melting-point metals plated or deposited on the
main element material to cause an “M” effect. If the
fuse is sized improperly, low level pulse currents may
cause the low-melting-point metals to alloy to the
element without completely opening the element.
A series of pulse currents will eventually create
enough heat to shift resistance or even permanently
open the fuse. Thus it is important to take into account
the number of pulse currents to which the fuse will be
subjected.
Solid matrix fuses (for example 0603FA or 3216FF
sized surface mount fuses) do not currently use an “M”
effect for the element construction. The element will
only then be affected by the thermal energy of each
pulse, and will not normally degrade as a result of
the number or frequency of pulses. Please refer to
Table 2 to determine the pulse factor, Fp.
For example, a pulse current with an I2t of 0.0823 and
a pulse factor, Fp=1.25 would require the selection of
a fuse to have a melting I2t greater than or equal to
0.1029.
Melting I2tfuse ≥I2tpulse xF
p
Melting I2tfuse ≥0.0823 x 1.25
Melting I2tfuse ≥0.1029

Fuse Technology
It is important to note that the melting I2t values of the
fuse and pulse current that are compared must be
calculated or tested at the same test conditions, most
importantly the magnitude of the peak current must be
the same. For example, if the pulse’s peak current is
15A, then the fuse’s melting I2t must be calculated at
15A as well to fully understand its electrical
characteristics at that magnitude of current. Please
contact CET directly for technical assistance.

Time vs. Current Curves
A time current curve represents the relationship
between a fuse’s melting or clearing time and the
magnitude of RMS or dc current. The characteristics
represented on most published graphs usually indicate
a fuse’s average melting time when subjected to a
certain level of current. The curves will typically
demonstrate the ability to carry 100% of rated current,
and then also represent the fuse’s ability to open within
the maximum opening time at designated overload
points (typically 135% to 300% of the fuse rating).
Time vs. current curves are a useful design aid for
an engineer when specifying a fuse type or rating for
an application. It is however recommended that fuse
samples be tested in the actual application to verify
performance.
Fuse Resistance
In most applications, the voltage drop across the fuse
due to its internal and contact resistance is negligible.
There are, however, certain critical applications where
the fuse resistance must be considered and it is
important that the circuit designer understands the
fuse characteristics in order to select the proper fuse.
Applications that are powered by low voltage batteries,
typically 3V or less, and utilize fractional rated fuses
with high resistance may require special attention be
given to the voltage drop across the fuse.
Physical Sizes
There are numerous physical sizes of electronic fuses,
including subminiature fuses. The most common fer-
rule designs are 5x15mm, 5x20mm and 6.3x32mm
(1/4” x 1 1/4”).
Subminiature fuses are often used when board space
is limited. For applications of this type, there are
through-hole and surface mount devices available.
Standard package sizes for surface mount fuses are
0402 (1005), 0603 (1608), 1206 (3216), 6125, and
1025. These sizes are standard throughout the elec-
tronic industry. Through-hole axial and radial leaded
products allow fuses to be PCB mounted. Standard
ferrule fuses fitted with leads can also be mounted in
this way.
Physical Sizes of Traditional Ferrule Fuses
Standards
North American UL/CSA and IEC standards require
significantly different time vs. current characteristics for
overcurrent devices.

Fuse Technology
Typically the physical dimensions and materials used
are similar; however, fuses built to different standards
are not interchangeable because their element melting
and opening times will differ when subjected to the
same magnitude of current. It is therefore important for
the circuit designer to consider that world standards
may require different fuses.
Glossary of Terms
Ampere squared seconds I2t
The melting, arcing, or clearing integral of a fuse,
termed I2t, is the thermal energy required to melt, arc,
or clear a specific current. It can be expressed as
melting I2t, arcing I2t or the sum of them, clearing I2t.
Arcing time
The amount of time from the instant the fuse link has
melted until the overcurrent is interrupted, or cleared.
Clearing time
The total time between the beginning of the overcur-
rent and the final opening of the circuit at rated voltage
by an overcurrent protective device. Clearing time is
the total of the melting time and the arcing time.
Fast acting fuse
A fuse which opens on overload and short circuits very
quickly. This type of fuse is not designed to withstand
temporary overload currents associated with some
electrical loads. UL listed or recognized fast acting
fuses would typically open within 5 seconds maximum
when subjected to 200% to 250% of its rated current.
IEC has two categories of fast acting fuses:
• F = quick acting, opens 10x rated current within
0.001 seconds to 0.01 seconds
• FF = very quick acting, opens 10x rated current in
less than 0.001 seconds
Fuse
An overcurrent protective device with a fusible link that
operates and permanently opens the circuit on an
overcurrent condition.
Overcurrent
A condition which exists in an electrical circuit when
the normal load current is exceeded. Overcurrents take
on two separate characteristics-overloads and short
circuits.
Overload
Can be classified as an overcurrent which exceeds the
normal full load current of a circuit by 2 to 5 times its
magnitude and stays within the normal current path.
Resistive load
An electrical load which is characterized by not draw-
ing any significant inrush current. When a resistive
load is energized, the current rises instantly to its
steady state value, without first rising to a higher value.
RMS Current
The R.M.S. (root mean square) value of any periodic
current is equal to the value of the direct current which,
flowing through a resistance, produces the same heat-
ing effect in the resistance as the periodic current
does.
Short circuit
An overcurrent that leaves the normal current path and
greatly exceeds the normal full load current of the cir-
cuit by a factor of tens, hundreds, or thousands times.
Time delay fuse
A fuse with a built-in time delay that allows temporary
and harmless inrush currents to pass without operat-
ing, but is so designed to open on sustained overloads
and short circuits. UL listed or recognized time delay
fuses typically open in 2 minutes maximum when sub-
jected to 200% to 250% of rated current. IEC has two
categories of time delay fuses:
• T = time lag, opens 10x rated current within 0.01
seconds to 0.1 seconds
• TT = long time lag, opens 10x rated current within
0.1 seconds to 1 second
Voltage rating
A maximum open circuit voltage in which a fuse can be
used, yet safely interrupt an overcurrent. Exceeding the
voltage rating of a fuse impairs its ability to clear an
overload or short circuit safely.

ESD Suppression Selection Guide
Our Voltage Variable Material (VVM) has unique
properties that are highly preferred in ESD suppres-
sion applications. The polymer matrix responds to
an over-voltage condition by rapidly changing from
a high impedance state to a low impedance state.
Cooper Bussmann utilizes this polymeric matrix in
PolySurg ESD Suppressors for fast response, ultra
low capacitance, and very low current leakage. The
device is activated by over-voltage threat and clamps
to a low value to protect sensitive circuit components.
What is it:
PolySurg™ ESD Suppressor Selection Guide:
The PolySurg TR and MLP Series are board level
circuit protection devices designed exclusively for the
fast, transient over-voltages associated with ESD.
When a sufficient over-voltage occurs it exhibits a dra-
matic increase in the ability to conduct electrons. The
nature of the material creates a bi-directional part,
which means that only one device is required to pro-
vide complete ESD protection regardless of the surge
polarity. In a typical application, the device is placed
across a signal line leading to an integrated circuit
and ground. The device exhibits minimal capacitance
and is “invisible” to the circuit during the normal oper-
ation. Under normal operating voltages (typically 3 to
15V) the high impedance of the device insulates each
signal line from ground. When an ESD event occurs,
the voltage variable material switches to a conductive
state within nanoseconds. The voltage across signal
line collapses to the clamping level, and current is
shunted through the device to the ground. When the
overvoltage event ends, the circuit returns to its
normal operating state as the device switches back to
its >1012Ohm, high resistance state and “invisibility.”
How it Works:
Features:
• Outstanding ESD protection for high frequency,
low voltage applications.
• Exceeds testing requirements outlined in IEC 61000-4-2
• Extremely low capacitance
• Very low leakage current
• Fast response time
• Bi-directional
• Surface mount
• Solder Termination

PolySurg™ ESD Suppressors are marked on the tape and reel packages, not individually. Since the product is bi-
directional and symmetrical, no orientation marking is required.
Device Marking
Full product characterization requires use of multiple test methods. Each test method reveals unique information
about the device response. The results of all of the tests must be analyzed to fully understand the PolySurg™ ESD
Suppressor response to an over-voltage event.
Test Methodology
Clamp Voltage – The voltage at which the PolySurg™ device stabilizes during the transition from high to low impedance. This is the voltage
experienced by the circuit, after stabilizing, for the duration of the ESD transient.
Trigger Voltage – The voltage at which the PolySurg™ device begins to function. When the ESD threat voltage reaches this level,
the PolySurg™ device begins the transition from high impedance to low impedance, shunting the ESD energy to ground.
Threat Voltage – The voltage that the test equipment is set to operate (i.e. the voltage across the discharge capacitor).
Peak Current – The maximum instantaneous current level that a device will receive. IEC-61000-4-2 states that the peak current should be
30A at 8kV ESD and 45A at 15kV ESD.
Definition of Terms
The ESD pulse is the defining test for an ESD protec-
tive device. The ESD pulse is an extremely fast rising
transient event. The pulse, as characterized in IEC
61000-4-2, has a rise time of less than 1ns, peak cur-
rents up to 45A, and voltage levels to 15 kV.
Characteristics determined by this test are those such
as voltage overshoot, peak voltage, clamping voltage,
peak current, and device resistance.
Due to the extremely fast rate of rise of the ESD pulse,
the test setup can have a definite impact on the above
factors. Variables such as wiring inductance and probe
capacitance can produce inaccurate readings on an
otherwise capable oscilloscope.

The Transmission Line Pulse tester implements a con-
trolled impedance cable to deliver a square wave current
pulse. The advantage of this technique is that the con-
stant current of the square wave allows the behavior of
the protection structure to be more accurately studied.
The actual implementation of this technique produces a
waveform that has a slightly slower rise time that the
ESD pulse but can be correlated to the deliver approxi-
mately the same surge current and energy. This con-
trolled impedance pulse provides a more accurate depic-
tion of the trigger voltage of the device because of the
reduced voltage overshoot caused by a fast rising tran-
sient and the reactive components of the test fixture.

ESD Transient Pulse Energy Controlled by
PolySurg™
Figure 1 shows typical PolySurg™ ESD Suppressor
response to an 8 kV contact ESD pulse. Triggered
polymer in the device conducts excess energy to ground
and prevents system damage by ESD transient threat. As
the polymer resistance drops current flows to ground.
The top scope trace indicates current, and the bottom
scope trace indicates voltage.
Protects against ESD Voltage Transient
without Affecting Signal Quality
PolySurg™ ESD Suppressors have an ultra low capaci-
tance of <0.15pF and when typically installed from the
signal line to ground have a negligible effect on the signal.
As Figure 2 shows, the test conducted with a precision
network analyzer on a 50 Ωcircuit at up to 6GHz. Only a
0.2dB deviation from the original signal was recorded.
The setup was similar to the addition of the PolySurg™
ESD Suppressor to a circuit with very fast digital signal or
a cellular phone antenna.
Signal Frequency does not affect the
Capacitance of the Device
The device capacitance is very low and constant over
wide frequency range. The typical capacitance is less than
0.15pF over the tested range of 0.1MHz to 1.8GHz. In
addition, as shown in Figure 3, the capacitance will
remain same over the life cycle of the device (i.e. the
number of the ESD pulse does not change the device
capacitance.)

Despite Repeated ESD Pulses
As Figure 4 shows, PolySurg™ ESD Suppressors are
highly reliable and stable over hundreds of pulses.
PolySurg™ ESD Suppressors have been tested with
fast rate ESD pulses at 8kV contact discharge.
Clamping voltage measured at every pulse shows
minimal changes throughout the test.
Typical non-triggered (Off State) Current
Leakage is Very Low at Normal Operating
Voltages and Temperatures
As shown by Figure 5 the current leakage of the
PolySurg™ ESD Suppressor is typically very low, well
under 1nA, even over 12VDC operating voltage.
Some increase in the current leakage may be
expected at much higher operating voltage and
elevated temperature.

The location in the circuit for the MLP series has to be carefully determined. For better performance, the device should be placed
as close to the signal input as possible and ahead of any other component. Due to the high current associated with an ESD
event, it is recommended to use a “0-stub” pad design (pad directly on the signal/data line and second pad directly on common
ground).

Device Marking
PolySurg™ ESD Suppressors are marked on the tape and reel packages, not individually. Since the product is bi-directional and
symmetrical, no orientation marking is required.
Design Consideration
The location in the circuit for the TR series has to be carefully determined. For better performance, the device should be placed
as close to the signal input as possible and ahead of any other component. Due to the high current associated with an ESD
event, it is recommended to use a “0-stub” pad design (pad directly on the signal/data line and second pad directly on common
ground).
Processing Recommendations
The TR series currently has a convex profile on the top surface of the part. This profile is a result of the construction of the deice.
They can be processed using standard pick-and-place equipment. The placement and processing techniques for these devices are
similar to those used for chip resistors and chip capacitors.

• IR Reflow = 260°C max for 10 sec. max.
• Wave Solder = 260°C max. for 10 sec. max.

Application Notes, ESD Suppression
What Are Set Top Boxes?
The continuing trend is to link broadband signal delivery to the
home entertainment display, and other devices via set top
boxes. Set top boxes used to be just an analog cable
tuner/decoder but now it includes the likes of digital cable,
satellite controller, internet service controllers, digital video
recording systems and home networking.
These devices allow the various cable and satellite signal oper-
ators to deliver a wide variety of services from television to
internet and the hardware manufacturers can provide many
features and benefits including home networking capabilities.
There is digital video recording onto hard disk drives, replacing
the cassette format, allowing pause and replay of and live tele-
vision, or interactive TV. There are new standards being creat-
ed to facilitate the design of the boxes such as a recent refer-
ence blueprint development by communications chipmaker
Broadcom using the Microsoft interactive TV software system.
The set top box is going to be a high volume commodity with
many forms and functions.
Why are Set Top boxes vulnerable to ESD
The more sophisticated boxes include a variety of I/O jacks
such as front panel USB, Audio/Video, S-Video, rear panel
Satellite, cable, TV antenna, Wireless transmitter connection,
home networking HPNA option, Toslink digital input, connec-
tions for CD, DVD,VCR, Outputs for Video, Audio, and more.
Most of these jacks are susceptible to ESD threat.
The PolySurg™ solution to the ESD protection problem
Utilize the 0402ESDA-MLP, 0603ESDA-MLP, or 0603ESDA-
TR1 PolySurg™ devices to protect the set top box electronics
from catastrophic ESD damage at each potential outside metal
contact or connector on each line. Audio, Video, RF, USB and
RS-232 lines may be protected from ESD TVS occurrences on
set top systems.
Design Wins with Set Top boxes
Cooper Bussmann has recorded some notable design wins
already with it’s PolySurg™ ESD Suppressors in applications
involving the protection of set top systems.

DVI/HDMI High Speed Date Rates
Communication data lines continue to be increasingly vul-
nerable to ESD transients. The ever-increasing bandwidth
of the faster data lines such as the 10/100 or Gigabit
Ethernet, USB 2.0, IEEE-1394b, make the traditional ESD
protection schemes such as silicon based devices, or multi
layer varistors less desirable, due to signal distortion from
the relatively high capacitance of these components.
PolySurg™ ESD Suppressors
The typical capacitance of the device (0402ESDA-MLP,
0603ESDA-MLP, or 0603ESDA-TR) is measured to be
below 0.15pF, in a range of 0.1 kHz to nearly 2 GHz. The
low capacitance throughout this wide frequency range
makes these devices suitable for ESD protection of low
analog signals to fast digital data lines.
Chart 1. The Capacitance of a PolySurg™ ESD
Suppressor from 0.1MHz to 1.8GHz
Another special characteristic of the PolySurg™ ESD
Suppressor is that it is virtually invisible to the circuit at
normal operation. The off-state resistance of the device is
over 1013 Ohms, and the typical current leakage of the
device is a negligible, 0.01nA at 12VDC. As Chart 2 shows,
the additional attenuation in a 50ohm circuit measured at
frequencies up to 6GHz is less than -0.2dbB.
Chart 2. Additional Attenuation in a 50Ohm System
due to the PolySurg™ ESD Suppressor
Example of devices that PolySurg™ ESD Suppressors can
protect from ESD:
• Network interface cards for desktops
• PC cards for laptops
• DSL / Cable modems.
• Routers and switches /hubs
Selected Protection Applications
Ethernet ports: The RJ-45 is the most common Ethernet
connection. The typical 10Base-T/100Base-TX uses 4 out
of 8 lines. Each line in use can be protected with one
PolySurg™ ESD Suppressor installed between the data line
and the ground. For the best performance, place the devices
at the closest location to the RJ-45 port (See Figure 1)
Figure 1. The ESD Protection of 10 / 100 Ethernet (RJ-45)
device with a PolySurg™ ESD Suppressor
Firewire: The IEEE-1394 (Firewire) series are the newest
serial ports for computer and other instruments with data
transfer rates up to 1,600Mbp (1394a is 400Mbps, and
1394b will be 800~1,6000Mbps.) This higher transfer
speed data is more easily subject to distortion (Chart 3).
The PolySurg™ ESD Suppressor can protect data lines
from ESD without distorting the high speed signal possible
from IEEE-1394 connection. All data lines should be
protected individually. (See Figure 2)

Example of devices that PolySurg™ ESD Suppressor can
protect from ESD:
• Firewire interface cards
• Digital camcorders
• Printers / scanners
• Other peripherals with Firewire capability
USB 2.0: The USB 2.0 has a fast data transfer rate of
400Mbps. A device equipped with USB 2.0 will give the
best performance when protected with the ultra low capaci-
tance PolySurg ESD Suppressor.This will result in much
less data distortion than if zener diodes or multi layer
varistors are used for ESD protection (See Figure 3)

Special Applications
When the unused data port is connected to a higher oper-
ating voltage such as 24V or higher for special applica-
tions, the PolySurg™ ESD Suppressor can be installed in
series for ESD protection on the higher voltage line. The
operating voltage capability will be increased without
changing total capacitance or the current leakage of the
devices.

High speed, uncompressed, digital video solutions such as Digital
Visual Interface (DVI) and High Definition Multimedia Interface
(HDMI) utilize small geometry CMOS processes in order to pro-
vide maximum performance in a small package. However these
geometries are more susceptible to electrostatic discharge (ESD)
and the high-speed digital signals present a real challenge when
selecting an appropriate protection device.
DVI/HDMI High Speed Date Rates
DVI equipment can, currently, transmit at up to 1.6 Gbps for a
1600 x 1200 resolution signal. The receiver end can support up to
1.08 Gbps for 1280 x 1024 resolution but will soon increase to
1.65 Gbps. HDMI is an advancement of DVI that handles both
audio and video signals with enough bandwidth for data rates of
up to 5 Gbps. These high-speed data rates require any ESD pro-
tection device to have low capacitance in order to minimize signal
distortion. At high frequency any capacitance will be seen as a low
impedance path to ground, thus loading the data signal. Figure 1
shows the minimal effect of of a PolySurg™ ESD Suppressor on
an 800 Mbps data signal compared to a 50pF capacitor.
Figure 1 – IEE1394 Signal Distortion due to 50pF and
0603ESDA PolySurg™ ESD Suppressor
Traditional low capacitance steering diode solutions have a num-
ber of problems when used in high-speed data applications such
as HDMI & DVI. Diodes are typically connected rail to rail as
shown in Figure 2. During a negative voltage transient the bottom
diode conducts clamping the voltage to a diode drop below
ground. During a positive voltage transient the top diode will con-
duct the surge current (I1) into the power rail. Dumping the surge
current into an unprotected supply rail can cause latch up of the
protection circuit, so an additional transient voltage suppression
(TVS) device between the supply rail and ground is required.
Typically discrete steering diodes are not rated for the high tran-
sient currents associated with ESD. This misuse results in a short
cycle life and eventual diode failure, which is commonly in short
circuit mode. This short circuit failure mode usually results in the
equipment no longer functioning, even though the ESD event has
passed. The preferred failure mode is open, since the equipment
will certainly not operate with a shorted device, but has a potential
to operate longer if the device were to fail open.
Figure 2 – Rail to Rail Diode Connection
In order to make a low capacitance diode a small junction area is
used which presents a high resistance during ESD transients.
Also, diode response time is slow compared to the ESD voltage
rise time and the complete solution has significant parasitic induc-
tance associated with the device leads and tracking. All this results
in a large amount of voltage overshoot and a much higher clamp-
ing voltage. With the HDMI/DVI chip still exposed to several hun-
dred or even one thousand volts following an ESD event, using
this protection technique, there is potentially enough stress to
damage the device.
Other solutions such as zener diodes, multi-layer varistors (MLV’s)
and TVS all exhibit levels of capacitance that are too large for
them to be practical solutions in DVI and HDMI applications. With
capacitance values from 25pF to 500pF coupled with leakage cur-
rents of 0.5-50μA the level of loading on the signal lines becomes
unacceptable.
PolySurg™ ESD Suppressor Product Family
The Cooper Bussmann PolySurg™ ESD Suppressor provides the
solution to the problem of providing ESD protection for these new
high-speed circuits. This product is a bi-directional device that has
leakage current of less than 1nA and capacitance less than
0.15pF. This ultra-low capacitance makes the PolySurg™ ESD
Suppressor a viable solution for high data rate protocols like HDMI
and DVI. With an insertion loss of less than -0.2dB at frequencies
up to 6GHz the PolySurg™ ESD Suppressor is invisible to the
circuit, introducing no additional loading or signal distortion.
The PolySurg™ ESD Suppressor product family is comprised of
the 0402ESDA-MLP, 0603ESDA-MLP, and 0603ESDA-TR series
ESD suppression devices. All are discrete devices exhibiting
ultra-low capacitance to maintain signal integrity while protecting
all but the most sensitive IC’s from the harmful effects of ESD
strikes up to 15kV (air discharge).
Summary
Commercial products require ESD surge protection of all the inter-
face hardware schemes. New higher end consumer electronics
are increasingly using high data rate protocols such as DVI and
HDMI. The traditional protection devices have all been used with
varying success, however the increase in data rates now indicates
a need for ultra low capacitance devices, such as Cooper
Bussmann’s PolySurg™ ESD Suppressors.

INDUCTOR SELECTION GUIDE
Inductor Selection Guide
High Current Shielded Drum (DR Style) Low Profile Shielded Drum (SD Style)
Note 1 = Current ratings listed are the lower value of the Isat and Irms ratings
Note 2 = EMI Rating: 1) Closed magnetic path - best EMI shield; 2) Small gap,
or external shield - some EMI fringing; 3) No shield - Highest EMI
Note 3 = Alternate sizes, terminal styles available
General information needed to select proper inductor:
___I. Inductance and Current requirements
___II. Mounting style (surface mount or thru hole) and
size constraints
___III. Frequency of operation (switching frequency)
___IV. Circuit susceptibility to EMI
___V. Consider using two parts in series for lower
profiles, higher current ratings or higher
inductance values

Note 1 = Current ratings listed are the lower value of the Isat and Irms ratings
Note 2 = EMI Rating: 1) Closed magnetic path - best EMI shield; 2) Small gap,
or external shield - some EMI fringing; 3) No shield - Highest EMI
Note 3 = Alternate sizes, terminal styles available
General information needed to select proper inductor:
___I. Inductance and Current requirements
___II. Mounting style (surface mount or thru hole) and
size constraints
___III. Frequency of operation (switching frequency)
___IV. Circuit susceptibility to EMI
___V. Consider using two parts in series for lower
profiles, higher current ratings or higher
inductance values

Notes: (1) Open Circuit Inductance Test Parameters: 1MHz, .100Vrms, 0.0Adc.
(2) RMS current for an approximate ΔT of 40°C without core loss. It is rec-
ommended that the temperature of the part not exceed 125°C.
(3) Peak current for approximately 30% rolloff at 20°C.
(4) DCR limits 20°C.
(5) Applied Volt-Time product (V-μS) across the inductor. This value repre-
sents the applied V-μS at 500KHz necessary to generate a core loss
equal to 10% of the total losses for 40°C temperature rise.

(1) Open Circuit Inductance Test Parameters: 100kHz, 0.1V, 0.0Adc.
(2) Irms: DC current for an approximate ΔT of 40°C without core loss. Derating is
necessary for AC currents. PCB layout, trace thickness and width, air-flow, and
proximity of other heat generating components will affect the temperature rise. It
is recommended that the temperature of the part not exceed 125°C under worst
case operating conditions verified in the end application.
(3) Isat Amperes peak for approximately 35% rolloff (@25°C)
(4) K-factor: Used to determine B p-p for core loss (see graph).
B p-p = K*L*ΔI, B p-p(mT), K: (K factor from table), L: (Inductance in μH),
ΔI (Peak to peak ripple current in Amps).

(1) Open Circuit Inductance Test Parameters: 100kHz, 0.25V, 0.0Adc.
(2) Irms: DC current for an approximate ΔT of 40°C without core loss. Derating is
necessary for AC currents. PCB layout, trace thickness and width, air-flow, and
proximity of other heat generating components will affect the temperature rise. It
is recommended that the temperature of the part not exceed 125°C under worst
case operating conditions verified in the end application.
(3) Isat Amperes peak for approximately 25% rolloff (@25°C)
(4) K-factor: Used to determine B p-p for core loss (see graph).
B p-p = K*L*ΔI, B p-p(mT), K: (K factor from table), L: (Inductance in μH),
ΔI (Peak to peak ripple current in Amps).
(5) Part Number Definition: DR124-xxx-R
DR124 = Product code and size; -xxx = Inductance value in uH;
R = decimal point; If no R is present, third character = # of zeros.
-R suffix = RoHS compliant

1) Open Circuit Inductance Test Parameters: 100kHz, 0.25 Vrms, 0.0 Adc
Parallel: (1,2 - 4,2) Series: (1 - 4) tie (2 - 3)
2) RMS current for an approximate ΔT of 40°C without core loss. It is recommend-
ed that the temperature of the part not exceed 125°C.
3) Peak current for approximately 30% roll-off at 20°C
4) DCR limits @ 20°C
5) Applied Volt-Time product (V-μS) across the inductor.This value represents the
applied V-μS at 100KHz necessary to generate a core loss equal to 10% of the
total losses for a 40°C temperature rise.
6) Turns Ratio (1-2):(3-4) 1:1

(1) Open Circuit Inductance Test Parameters: 100kHz, 0.1V, 0.0Adc.
(2) Irms: DC current for an approximate ΔT of 30°C without core loss. Derating is
necessary for AC currents. PCB layout, trace thickness and width, air-flow, and
proximity of other heat generating components will affect the temperature rise. It
is recommended that the temperature of the part not exceed 125°C under worst
case operating conditions verified in the end application.
(3) Isat Amperes peak for approximately 15% rolloff (@25°C)
(4) K-factor: Used to determine B p-p for core loss (see graph).
B p-p = K*L*ΔI, B p-p(mT), K: (K factor from table), L: (Inductance in μH),
ΔI (Peak to peak ripple current in Amps).

(1) Open Circuit Inductance Test Parameters: 100kHz, 0.1V, 0.0Adc.
(2) Irms: DC current for an approximate ΔT of 40°C without core loss. Derating is
necessary for AC currents. PCB layout, trace thickness and width, air-flow, and
proximity of other heat generating components will affect the temperature rise. It
is recommended that the temperature of the part not exceed 125°C under worst
case operating conditions verified in the end application.
(3) Isat Amperes peak for 30% maximum rolloff (@25°C)
(4) K-factor: Used to determine B p-p for core loss (see graph).
B p-p = K*L*ΔI, B p-p(mT), K: (K factor from table), L: (Inductance in uH),
ΔI (Peak to peak ripple current in Amps).
(5) Part Number Definition: SDH3812-xxx-R
SDH3812 = Product code and size; -xxx = Inductance value in uH;

1) Test Parameters: 100kHz,.0.25 Vrms 0.0Adc
2) Rms current for approximately ΔT of 40°C without core loss. It is recommended
that the temperature of the part not to exceed 125°C. De-rating is necessary for
AC currents
3) Peak current for approximately 30% rolloff @20°C
4) DCR limits @20°C
5) Applied Volt-Time product (V-μS) across the inductor at 100kHz necessary to
generate a core loss equal to 10% of the total losses for a 40°C temperature
rise. De-rating of the Irms is required to prevent excessive temperature rise.

(1) Open Circuit Inductance Test Parameters: 100kHz, 0.1V, 0.0Adc.
(2) Irms: DC current for an approximate ΔT of 40°C without core loss. Derating is
necessary for AC currents. PCB layout, trace thickness and width, air-flow, and
proximity of other heat generating components will affect the temperature rise. It
is recommended that the temperature of the part not exceed 125°C under worst
case operating conditions verified in the end application.
(3) Isat Amperes peak for approximately 35% rolloff (@25°C)

Notes: (1) Open Circuit Inductance Test Parameters: 100 kHz, .25Vrms, 0.0Adc.
(2) DCR limits 20°C.
(3) RMS current for an approximate ΔT of 40°C without core loss. It is rec-
ommended that the temperature of the part not exceed 125°C.
(4) Peak current for approximately 30% rolloff at 20°C.
(5) Applied Volt-Time product (V-μS) across the inductor.This value repre-
sents the applied V-μS at 300KHz necessary to generate a core loss
equal to 10% of the total losses for 40°C temperature rise.

VERSA-PAC temperature rise depends on total power losses and
size. Any other PCM configurations other than those suggested
could run hotter than acceptable.
Certain topologies or applications must be analyzed for needed
requirements and matched with the best VERSA-PAC size and con-
figuration. Proper consideration must be used with all parameters,
especially those associated with current rating, energy storage, or
maximum volt-seconds.
VERSA-PAC should not be used in off-line or safety related appli-
cations.The breakdown voltage from one winding to any other wind-
ing is 500 VAC maximum. PCM
(1) The first three digits in the part number signify the size of the pack-
age. The next four digits specify the AL, or nanoHenries per turn
squared.
(2) LBASE = Nominal Inductance of a single winding.
(3) IBASE is the lessor of ISAT(BASE)and IRMS(BASE).
(4) Peak current that will result in 30% saturation of the core. This cur-
rent value assumes that equal current flows in all six windings. For
applications in which all windings are not simultaneously driven (i.e.
flyback, SEPIC, Cuk, etc.), the saturation current per winding may
be calculated as follows:
ISAT = 6 x ISAT(BASE)
Number of Windings Driven
(5) RMS Current that results in a surface temperature of approximately
40°C above ambient. The 40°C rise occurs when the specified cur-
rent flows through each of the six windings.
(6) Maximum DC Resistance of each winding.
(7) For multiple windings in series, the volt-μsecondTOTAL (μVs)
capability varies as the number of windings in series (S):
Volt-μsecTOTAL = S xVolt-μsec(BASE)
For multiple windings in parallel, the volt-μsecondTOTAL (μVs) capability
is as shown in the table above.
(8) Maximum Energy capability of each winding. This is based on 30%
saturation of the core:
EnergySERIES = S2x1x0.7LBASE xI2
SAT(BASE)
EnergyPARALLEL = P2x1x0.7LBASE xI2
SAT(BASE)
For multiple windings, the energy capability varies as the square of
the number of windings. For example, six windings (either parallel
or series) can store 36 times more energy than one winding.
(9) Thermal Resistance is the approximate surface temperature rise
per Watt of heat loss under still-air conditions. Heat loss is a combi-
nation of core loss and wire loss. The number assumes the under-
lying PCB copper area equals 150% of the component area.
(10) These devices are designed for feed-forward applications, where
load current dominates magnitizing current.

Discrete inductors combine like resistors, when connected in series or parallel. For example, inductors in series add and
inductors in parallel reduce in a way similar to Ohm’s Law.
Windings on the same magnetic core behave differently. Two windings in series result in four times the inductance of a
single winding. This is because the inductance varies proportionately to the square of the turns.
Paralleled VERSA-PAC windings result in no change to the net inductance because the total number of turns remains
unchanged; only the effective wire size becomes larger. Two parallel windings result in approximately twice the current
carrying capability of a single winding. The net inductance of a given PCM configuration is based on the number of
windings in series squared multiplied by the inductance of a single winding (LBASE). The current rating of a PCM configuration
is derived by multiplying the maximum current rating of one winding (IBASE) by the number of windings in parallel. Examples of
simple two-winding devices are shown below:
LSeries = L1 + L2 + L3...Ln
LParallel = 1/ [1/L1 + 1/L2 + 1/L3....1/Ln]

TRANSFORMERS (VP1-5/VPH1-5) VERSA-PAC
®
Each VERSA-PAC can be configured in a variety of ways by simply connecting pins together on the Printed Circuit Board
(PCB). As shown below, the connections on the PCB are equal to the pin configuration statement shown at the bottom of the
schematic symbol. Connecting a number of windings in parallel will increase the current carrying capability, while connecting
in series will multiply the inductance. Each VERSA-PAC part can be configured in at least 6 combinations for inductor use or
configured in at least 15 turns ratios for transformer applications. Given 25 VERSA-PAC part numbers, this allows for at least
500 magnetic configurations. The PCM configurations can either be created by the designer or simply chosen from the
existing PCM diagrams. The following inductor example shows 6 windings in series, which result in an inductance of 36 times
the base inductance and 1 times the base current.

HOW TO PIN-CONFIGURE VERSA-PAC®
The PCM configurations may be selected from the examples on the following pages or created by the designer. Six PCM
inductor and fifteen PCM transformer configurations and equivalent circuit schematics are shown.The printed circuit board
layout in each example illustrates the connections to obtain the desired inductance or turns ratio. The examples may be
used by the PCB designer to configure VERSA-PAC as desired.
To assist the designer, VERSA-PAC phasing, coupling and thermal issues have been considered in each of the PCM
configurations illustrated. Additionally, the inductance and current ratings, as a function of the respective base values from
the following Data Tables, are shown in each PCM example.Turns ratios are also given for each PCM Transformer shown.
It is important to carefully select the proper VERSA-PAC part in order to minimize the component size without exceeding
the RMS current capability or saturating the core. The Data Tables indicate maximum ratings.

TRANSFORMERS (VP1-5/VPH1-5) VERSA-PAC
®
5V to 3.3V Buck Converter With 5V Output
This circuit minimizes both board space and cost by eliminating a
second regulator. VERSA-PAC’s gap serves to prevent core
saturation during the switch on-time and also stores energy for the
+5V load which is delivered during the flyback interval. The +3.3V
buck winding is configured by placing two windings in series while
the +5V is generated by an additional flyback winding stacked on
the 3.3V output. Extra windings are paralleled with primary
windings to handle more current. The turns ratio of 2:1 adds 1.67V
to the +3.3V during the flyback interval to achieve +5V.

3.3V Buck Converter
This circuit utilizes the gap of the VP5-0083 to handle the 12.5
Amp output current without saturating. In each of the five VERSA-
PAC sizes, the gap is varied to achieve a selection of specific
inductance and current values (see VERSA-PAC Data Table).
All six windings are connected in parallel to minimize AC/DC cop-
per losses and to maximize heat dissipation. With VERSA-PAC,
this circuit works well at or above 300 KHz. Also, the closed flux-
path EFD geometry enables much lower radiation characteristics
than open-path bobbin core style components.
LITHIUM-ION BATTERY TO 3.3V SEPIC CONVERTER
The voltage of a Lithium-Ion Battery varies above and below
+3.3V depending on the degree of charge. The SEPIC configura-
tion takes advantage of VERSA-PAC’s multiple tightly coupled
windings. This results in lower ripple current which lowers noise
and core losses substantially. The circuit does not require a snub-
ber to control the voltage “spike” associated with switch turn-off,
and is quite efficient due to lower RMS current in the windings.

Notes: (1) Open circuit inductance test parameters: 100kHz, 0.250Vrms, 0 Adc.
(2)
DC current for an approximate ΔT of 30°C at 75°C Ambient with no core loss. See Chart 2 for derating of IDC with core loss.
(3) Peak current for an approximate 30% roll-off in OCL. For other current levels see Chart 1.
(4) Applied Volt-Time product (VμS) across the inductor. This value represents the VμS at 100kHz necessary to generate a core loss equal to 10% of the total
losses for 30°C rise. For other frequencies and operating levels see Chart 2. (Note: skin effect losses not included.)
(5) Energy storage (μJ) at ISAT. For other current levels see Chart 1.
(6) Maximum D.C. resistance at 20°C.

APPLICATION NOTES
Using the Versa-Pac as a Flyback Transformer
The Versa-Pac range of transformers is one of the many
products manufactured under the Cooper Coiltronics®
brand of power magnetics from Cooper Bussmann.
Versa-Pac is available in five sizes and is suitable for
flyback circuits with power levels up to 35W and a maxi-
mum switching frequencies of 500kHz. The VP series
was designed, primarily, for low voltage applications
typically 3.3V, 5V and 12V. With the addition of the VPH
products to the range the Versa-Pac can now be used
for 24V, 48V and, at higher frequencies, even 120V
applications. Each transformer has six identical windings
that can be configured in series and parallel to produce
the required transformer design, the isolation between
these windings is 500Vdc. Full product data is available
on our website: www.cooperbussmann.com
Design Procedure
In order to design a flyback transformer using the Versa-
Pac the following information is required: nominal, mini-
mum and maximum input voltages (Vin(nom), Vin(min) &
Vin(max)), output voltage (Vo), output current (Io) and
switching frequency (Fs).
For the purpose of our example let’s take the following
values:
Vo = 5V, Io = 1A, Vin(min) = 40V, Vin(nom)=48V ,
Vin(max) = 56V and Fs = 200kHz
Using the graph for Unipolar (Flyback) Power v
Frequency from the data sheet select the required Versa-
Pac size by reading off your required output power and
operating frequency.
At 200kHz and 5W this gives a VP3 size.
If the output power requirement can’t be met then the
Versa-Pac is unable to offer a flyback transformer solu-
tion. It may be worth considering a Push-Pull topology, as
this will give better transformer utilization allowing high
output power levels for the same transformer size.
Calculate the turns ratio for a duty cycle (D) of 0.5 using
the equation;
Vo/Vin(nom) = Nsec/Npri x (D/1-D) (1)
Where Nsec is the number of secondary windings and
Npri is the number of primary windings, Npri/Nsec is the
turns ratio which must be rounded to the nearest achiev-
able value (i.e. 0.5, 0.667, 1, 1.5, 2, 3 etc).
5/48 = Nsec/Npri x 0.5/(1-0.5)
Npri/Nsec = (48x1)/5 = 9.6
Rounding down, Npri/Nsec = 5 (max ratio)
Vin(nom) and 0.5 duty cycle are used only as a starting
point, it is possible that using Vin(min) with lower or high
duty cycles you may achieve a more suitable turns ratio.
Calculate the actual duty cycle for Vin(max) using equa-
tion 1 and the calculated turns ratio rounded up or down
to the nearest achievable value.
5/56 = (1/5) x D/(1-D)
0.446-0.446D = D
D = 0.446/1.446 = 0.309
Calculate the primary volt-seconds product using the fol-
lowing equation:
Primary Vs = D x Ts x Vin(max)
Where Ts = 1/Fs (2)
This value should be less than the rated primary Volt-
μsec, if the primary uses one winding the rated Volt-μsec
is the same as Volt-μsec(Base). If the primary is two
windings in series then the rating is then 2 x Volt-
μsec(Base) and for 3 series windings 3 x Volt-μsec(Base)
etc. If the Volt-μsec rating can not be achieved using the
selected Versa-Pac size then you will need to select a
larger size or increase the switching frequency.

Primary Vs = 0.309 x 1/200x103x 56 = 86.52Vμsec
The VP3 has a Volt-μsec(Base) of 27.7Vμsec, multiply-
ing this by 5 gives a rating of 138.5Vμsec. So the VP3
size meets the volt-seconds requirements.
If the required volt-seconds rating can’t be achieved you
can reduce the required rating by increasing the switching
frequency. Alternatively you can recalculate the turns ratio
using Vin(min) as this may increase the number of series
primary windings.
Starting with the highest inductance value for the selected
VP size, calculate the output current at which current con-
duction is at the boundary between continuous and dis-
continuous.
Io (boundary) = Ts x Vo x (1-D(max))2/(2 x Ls) (3)
Where Ls is the secondary inductance and Dmax is the
duty cycle at Vin(min).
Selecting the VP3-0780:
D(max) = 0.625/1.625 = 0.385
Ls = 63.2μH
Io (boundary) = 5x10-6 x 5 x (1-0.385)2/
(2 x 63.2x10-6) = 0.075A
As the boundary current is less than the maximum
output current the transformer is operating in contin-
uous mode.
Calculating the peak and rms primary currents we can
determine if the selected Versa-Pac meets the specified
requirements.
For Continuous mode conduction:
Peak Primary Current:
Ipri(peak) = Nsec/Npri x (1/1-D(max))
x Io + (Vin(min) x Ts x D(max))/2 x Lpri (4)
Where Lpri is the primary inductance.
In order to calculate the rms primary current you first
need to calculate the primary current delta and average
peak.
ΔIpri = (Vin(min) x D(max) x Ts)/Lpri (5)
Ipri(avg-pk) = (Ipri(peak) + (Ipri(peak) - ΔIpri))/2 (6)
Ipri(rms) = (D(max) x (Ipri(avg-pk))2)0.5 (7)
Ipri(peak) = 0.2 x 1/(1-0.385) + (40 x 5x10-6 x 0.385)/
(2 x 52x 63.2x10-6) = 0.35A
Peak current is higher than the Isat rating for the
VP3-0780, which is equal to 6/5 x Isat(base). So mov-
ing up to the VP3-0138, we once again find that con-
duction is mainly continuous mode and so peak pri-
mary current:
Ipri(peak) = 0.2 x 1/(1-0.385) + (40 x 5x10-6 x 0.385)/
(2 x 52x 11.2x10-6) = 0.462A
ΔIpri = (40 x 0.385 x 5x10-6)/(52x 11.2x10-6) = 0.275A
Ipri(avg-pk) = (0.462 + (0.462 – 0.275))/2 = 0.325A
Ipri(rms) = (0.385 x 0.3252)0.5 = 0.202A
For the VP3-0138 the Irms rating is 1.47A and the
Isat(base) is 0.59A both of which are sufficiently high
to meet the primary current requirements.
For discontinuous mode conduction:
First we need to calculate the average primary current:
Ipri(avg)= (Vo x Io)/(Vin(min) x Efficiency) (8)
Ipri(peak) = (2 x Ipri(avg))/D(max) (9)
Ipri(rms) = ((Ipri(peak)2x D(max))/3)0.5 (10)
You can now check these results against the Isat and
Irms ratings, bearing in mine that the actual Isat rating:
= (6 x Isat(base))/Number of windings driven (11)
The number of windings driven for a flyback transformer
is the number of series windings used to make up the pri-
mary. So for two series primary windings the rated Isat is
actually 3 times Isat(base).
Finally, calculate the maximum rms secondary current,
For continuous mode:
Isec(rms) = ((1-D(max)) x (Io/(1-D(max)))2)0.5 (12)

Application Notes
Magnetics
For discontinuous mode:
Isec(rms) = ((1-D(max))/3 x (Isec(peak))2)0.5 (13)
Where, referring to equation 9:
Isec(peak) = Ipri(peak) x Npri/Nsec (14)
Isec(rms) = ((1-0.385) x (1/(1-0.385))2)0.5 = 1.275A
The VP3-0138 has an Irms(base) rating of 1.47A
Examples:
SLIC Power Supply
By connecting three secondary windings in series much
higher output voltages can be achieve, in this example
each secondary winding has a -24V output therefore pro-
viding the -48V and -72V supplies required in SLIC appli-
cations.
Split +/-12V Supply
Using a secondary center tap allows the winding to be
configured for positive and negative outputs. Extra wind-
ings are paralleled with the primary and secondary wind-
ings in order handle more current and reduce losses.

Using the Versa-Pac as a Forward Converter Transformer
The Versa-Pac range of transformers is one of the many
products manufactured under the Cooper Coiltronics®
brand of power magnetics from Cooper Bussmann.
Versa-Pac is available in five sizes and is suitable for a
maximum switching frequency of 500kHz and power
levels up to 30W, for single ended topologies, or 60W for
bipolar applications. The VP series was designed,
primarily, for low voltage applications typically 3.3V, 5V
and 12V. With the addition of the VPH products to the
range the Versa-Pac can now be used for 24V, 48V and,
at higher frequencies, even 120V applications. Each
transformer has six identical windings that can be
configured in series and parallel to produce the required
transformer design, the isolation between these windings
is 500Vdc. Full product data is available on our website:
www.cooperbussmann.com
Single Ended Forward Converter Design Procedure
In order to design a forward converter transformer using
the Versa-Pac the following information is required: nomi-
nal, minimum and maximum input voltages (Vin(nom),
Vin(min) & Vin(max)), output voltage (Vo), output current
(Io) and switching frequency (Fs).
For the purpose of our example let’s take the following
values:
Vo = 3.3V, Io = 5A, Vin(min) = 40V, Vin(nom)=48V ,
Vin(max) = 56V and Fs = 250kHz
Using the graph for unipolar (Flyback) Power v Frequency
from the data sheet select the required Versa-Pac size by
reading off your required output power and operating fre-
quency.
At 250kHz and 16.5W this gives a VP5 size.
Although the data used in the Power v. Frequency curve
was derived using a flyback topology, as a guide to
Versa-Pac size requirements, it still holds true for unipolar
forward converters.
Calculate the turns ratio for a duty cycle (D) of 0.25 using
the equation;
Vo/Vin(nom) = D x Nsec/Npri (1)
Where Nsec is the number of secondary windings and
Npri is the number of primary windings, Npri/Nsec is the
turns ratio which must be rounded to the nearest achiev-
able value (i.e. 0.5, 0.667, 1, 1.5, 2, 3 etc).
3.3/48 = Nsec/Npri x (0.25)
Npri/Nsec = (48x0.25)/3.3 = 3.6
Rounding down, Npri/Nsec = 3
Vin(nom) and 0.25 duty cycle are used only as a starting
point, it is possible that using Vin(min) with lower or high
duty cycles you may achieve a more suitable turns ratio.
Note: Maximum duty cycle for most unipolar forward con-
verters is 0.5.
Calculate the maximum duty cycle for Vin(min) using
equation 1 and the calculated turns ratio rounded up or
down to the nearest achievable value.
3.3/40 = 1/3 x (D)
(3.3 x 3)/40 = D
D(max) = 0.2475
Calculate the primary volt-seconds product using the fol-
lowing equation:
Primary Vs = D(max) x Ts x Vin(min)
Where Ts = 1/Fs (2)
This value should be less than the rated primary Volt-
μsec, if the primary uses one winding the rated Volt-μsec
is the same as Volt-μsec(Base). If the primary is two
windings in series then the rating is then 2 x Volt-
μsec(Base) and for 3 series windings 3 x Volt-μsec(Base)
etc. If the Volt-μsec rating can not be achieved using the
selected Versa-Pac size then you will need to select a
larger size or increase the switching frequency.

The VP5 has a Volt-μsec(Base) of 65.6Vμsec, multiply-
ing this by 3 gives a rating of 196.8Vμsec. So the VP5
easily meets the volt-seconds requirements.
If the required volt-seconds rating can’t be achieved you
can reduce the required rating by increasing the switching
frequency. Alternatively you can recalculate the turns ratio
using Vin(max) or a high duty cycle as this may increase
the number of series primary windings.
Starting with the highest inductance value for the selected
VP, calculating the rms primary currents we can deter-
mine if the selected Versa-Pac meets the specified
requirements.
In order to calculate the rms primary current you first
need to calculate the peak current.
Ipri(peak) = Nsec/Npri x (Io + ΔIo/2) + Imag(peak) (3)
Where:
Imag(peak) = (Vin(min) x Ts x D(max))/Lpri (4)
Primary rms current:
Ipri(rms) = (D(max) x (Ipri(avg-pk))2)0.5 (5)
Where:
Ipri(avg-pk) = (Ipri(peak) + (Ipri(peak) -
Imag(peak)))/2 (6)
Assuming ΔIo is set to 10% of Io max, which is achieved
by selection of the correct output inductor value (see
application note EUA001). Using a VP5-1200, the L(base)
is 76.8μH therefore:
Imag(peak) = (40 x 1/250x103x 0.248)/
32x 76.8 x10-6= 0.0574A
Ipri(peak) = 1/3 x (5 + (0.5/2) + 0.0574 = 1.81A
Ipri(avg-pk) = (1.81 + (1.81 – 0.0574))/2 = 1.78A
Ipri(rms) = (0.248 x 1.782)0.5 = 0.89A
The rms current rating, Irms(base), for the VP5-1200
is 2.08A
Finally, calculate the maximum rms secondary current,
Isec(rms) = (D(max) x (Io + Isec(peak)/2)2)0.5 (7)
Where, referring to equation 3:
Isec(peak) = Ipri(peak) x Npri/Nsec (8)
Isec(peak) = 1.81 x 3 = 5.43A
Isec(rms) = (0.248 x ((5 + 5.43)/2)2)0.5 = 2.6A
The rms current rating, Irms(base), for the VP5-1200
is 2.08A. In order to achieve the required rms current
rating at least two parallel windings must be used to
make up the secondary. For improved efficiency it
would be normal practice to use both the spare wind-
ings and have a secondary made up of three parallel
windings.
Transformer Reset
In a practical single ended forward converter design you
need to consider how transformer reset is going to be
achieved. During the switch ‘ON’ period current propor-
tional to the output current plus the magnetizing current
flow in the primary winding, the magnetizing current must
be reset to zero during the switch ‘OFF’ period in order to
prevent converter failure. This can be achieved in a
number of ways, figure 1 shows a method that uses an
auxiliary primary winding connected in anti-phase to the
main primary. This additional winding acts in flyback
mode during the switch ‘OFF’ period recovering the
magnetizing energy in to the supply rail.
Figure 1
For Versa-Pac designs this method limits the converter
maximum duty cycle to 50% and also reduces the num-
ber of possible configurations, as only 5 windings will be
available. Figure 2 shows a simple way of resetting the
transformer using an resistor-capacitor-diode (RCD) net-
work which allows all 6 windings to be used when config-
uring the transformer.

Figure 2
Using an RCD reset network has a number of advan-
tages, it reduces the voltage stress on the switch, it limits
turn off voltage spike and permits operation at greater
than 50% duty cycle. Figure 3 shows a reset method for a
dual switch topology, this method allows the primary
winding to operate in flyback mode with the current flow-
ing through the two recovery diodes. This technique is
similar to that shown in figure 1, the advantages of this
topology include reduced voltage rating requirement for
the switches and no requirement for an auxiliary primary
winding.

Power Inductors Improve Reliability in High Temperature Designs
The Cooper Coiltronics®brand of High Current FP3™
power inductors from Cooper Bussmann is designed for
high density, medium current applications using a high
temperature iron powder core material. These inductors
do not exhibit the thermal aging issue frequently
associated with iron powder core inductors. In fact the
FP3 core is rated for 200°C without thermal degradation.
The FP3 family is rated for 155°C operation. The
calculations below will allow users to take advantage of
this high temperature capability.
In this example, a buck regulator will be used to convert
a 12V input to a 5V output with a load current of 4.5A.
The operating frequency was chosen to be 600 kHz to
reduce the size of the filter components, while still main-
taining good efficiency. The converter is designed to
have 20% ripple current, so a relatively low ESR output
filter capacitor will be used, as is typical in switching
power supplies.
First calculate the needed inductance value:
V = L * dI/dt where:
V = Vin - Vout (voltage across the inductor)
dT = On time of drive = Vout/Vin/frequency
ΔI = Chosen above to be 20%
Calculate the required inductance:
L = V * dt / ΔI = (12-5)*(12/5/600k)/(0.2*4.5)
L= 4.8 μH
Choose 4.7 μH, the nearest standard value
Recalculate ripple current at 23% using 4.7 μH
Second determine peak to peak flux density, Bp-p:
Bp-p = K * L * ΔI where:
K: K-factor from the adjacent table
L: Inductance μH
ΔI: Peak to peak ripple current (Amps)
Bp-p = 105*4.7*0.23*4.5 = 510 Gauss
Next determine the total losses in the inductor:
Total losses = DC loss + AC loss
DC loss = I2*DCR = 4.52* 0.040 = 0.81 W
(DCR from FP3 datasheet)
AC loss from table at Bp-p of 510 = 0.15 W
Total Loss = DC loss + AC loss = 0.96W
Finally determine the temperature rise.
Total loss = 0.96W, using the table,
Temperature rise is 80°C
Assuming an ambient temperature of 70°C,
The temperature of the inductor is
T = 70 +75 = 150°C

APPLICATION NOTES
Switching Regulator Inductor Design
In switching regulator applications the inductor is used as
an energy storage device, when the semiconductor
switch is on the current in the inductor ramps up and
energy is stored. When the switch turns off this energy is
released into the load, the amount of energy stored is
given by;
Energy = 1/2L.I2(Joules) (1)
Where L is the inductance in Henrys and I is the peak
value of inductor current.
The amount by which the current changes during a
switching cycle is known as the ripple current and is
defined by the equation;
V1= L.di/dt (2)
Where V1is the voltage across the inductor, di is the rip-
ple current and dt is the duration for which the voltage is
applied. From this we can see that the value of ripple cur-
rent is dependent upon the value of inductance.
Choosing the correct value of inductance is important in
order to obtain acceptable inductor and output capacitor
sizes and sufficiently low output voltage ripple.
Figure 1
As can be seen from figure 1 inductor current is made up
of AC and DC components, because the AC component
is high frequency it will flow through the output capacitor
as it has a low HF impedance. This will produce a ripple
voltage due to the capacitor ‘equivalent series resistance’
(ESR) that will appear at the output of the switching regu-
lator. This ripple voltage needs to be sufficiently low as
not to effect the operation of the circuit the regulator is
supplying, normally in the order of 10-500mVpk-pk.
Selecting the correct ripple current also impacts on the
size of inductor and output capacitor, the capacitor will
need to have a sufficiently high ripple current rating or it
will overheat and dry out. In order to get a good compro-
mise between inductor and capacitor size a ripple current
value of 10-30% of maximum inductor current should be
chosen. This also means that the current in the inductor
will be continuous for output currents greater that 5-15%
of full load.
Inductor Selection for Buck Converters
When selecting an inductor for a Buck converter, as with
all switching regulators, you will need to define or calcu-
late the following parameters:
• Maximum input voltage
• Output voltage
• Switching frequency
• Maximum ripple current
• Duty cycle
For the example shown in figure 2 lets assume a switch-
ing frequency of 250kHz, input voltage range of
12V±10% and a max ripple current of 220mA.
Figure 2
For an input voltage of 13.2V the duty cycle will be:
D = Vo/Vi= 5/13.2 = 0.379 (3)
Where Vois the output voltage and Viis the input volt-
age.
Voltage across the inductance:
V1= Vi- Vo= 8.2V when the switch is on (4)
V1= - Vo= -5V when the switch is off (5)
Require inductance:
L = V1.dt/di = (8.2 x 0.379/250 x 103)/0.22 (6)
L = 56.5μH

Inductor Selection for Boost Converters
In order to calculate the require value of inductance for
a Boost converter we follow the same procedure as
described for the Buck converter, the difference being that
the equations for duty cycle and inductor voltage change.
Taking maximum input voltage as 5.5V, switching
frequency as 100kHz and maximum ripple current as
0.1A.
Figure 3
Duty cycle:
D = 1 – (Vi/Vo) = 1 – (5.5/12) = 0.542 (7)
Inductor Voltage:
V1= Vi= 5.5V when the switch is on (8)
V1= Vo– Vi= 6.5V when the switch is off (9)
Using equation 6, inductance:
L = (5.5 x 0.542/100 x 103)/0.1
L = 298μH
One thing to note about the Boost converter topology is
that, unlike the Buck converter, inductor current does not
continuously flow to the load. During the switch ‘on’ period
the inductor current flows to ground and the load current
is supplied from the output capacitor. This means that the
output capacitor must have sufficient energy storage
capability and ripple current rating in order to supply the
load current during this period.
Inductor Selection for Buck-Boost Converters
(including Cuk & SEPIC)
The procedure shown here is for the Cuk converter but it
applies equally well to the SEPIC and the single inductor
Buck-Boost topologies. Initially we will consider the circuit
utilizing two separate inductors of equal value and then
look at some of the advantages of using coupled inductors.
For this example we shall use a switching frequency of
200kHz and a maximum ripple current of 200mA.
Figure 4
Duty cycle:
D = Vo/(Vo+ Vi) = 12/(12+18) = 0.4 (10)
Inductor voltages:
V1= Vi= 18V when the switch is on (11)
V1= Vo= 12V when the switch is off (12)
Using equation 6, inductance:
L = (18 x 0.4/200 x 103)/0.2
L = 180μH
Both the SEPIC and Cuk topologies offer advantages
over the single inductor Buck-Boost design. Input current
is continuous resulting in lower peak values, drive circuit
requirements are simple due to switch location and the
use of a coupled inductor reduces the cost and PCB
space penalties of these topologies.
One thing to note when using coupled inductors, for the
total ripple current and total inductive energy stored to
remain the same the inductance of each winding should
be halved (for our example Lcouple = 90μH).

Inductor Selection for SEPIC Designs
The SEPIC (single-ended primary inductance converter)
in an increasingly popular topology, particularly in battery
powered applications, as the input voltage can be higher
or lower than the output voltage. This presents obvious
design advantages but for many engineers the circuit
operation and component selection is a mystery, for those
that understand the basics the addition of a coupled
inductor is an added complication. This article looks at the
operation of the SEPIC and compares the design proce-
dure for two single winding inductors with a coupled
inductor approach.
Basic Operation
Figure 1 shows the simple circuit diagram for a SEPIC,
during the switch (SW) ON time the voltage across both
inductors is equal to Vin. This is obvious for L1, however it
is not so clear for L2. In order to understand this we first
need to look at the voltage across Cp, neglecting ripple
voltage, this voltage is constantly at the value of Vin. The
simplest way to see this is when the circuit is at equilibri-
um, under these conditions there is no DC voltage across
L1 or L2, so one side of the capacitor is at Vin and the
other at zero volts.
When the switch is ON capacitor Cp is connected in par-
allel with L2, hence the voltage across L2 is the same as
the capacitor voltage, -Vin. This in turn means that diode
D1 is reverse bias and the load current is being supplied
by capacitor Cout. During this period energy is being
stored in L1 from the input and in L2 from Cp.
Figure 1 - Simple SEPIC Circuit
When the switch turns off the current in L1 continues to
flow through Cp, D1 and into Cout and the load recharg-
ing Cp ready for the next cycle. The current in L2 also
flows into Cout and the load, ensuring that Cout is
recharged ready for the next cycle.
During this period the voltage across both L1 and L2 is
equal to Vout, once again this is fairly clear for L2 but no
so for L1. However we already know that the voltage
across Cp is equal to Vin and that the voltage on L2 is
equal to Vout, in order for this to be true the voltage at the
node of Cp and L1 must be Vin + Vout. This in turn
means that the voltage across L1 is (Vin+Vout) – Vin =
Vout.
Inductor Selection
First, let us look at the selection of two separate inductors
for L1 and L2 in the following example:
Input voltage (Vin) – 2.8V – 4.5V
Output (Vout & Iout) – 3.3V, 1A
Switching Frequency (Fs) – 250kHz
Efficiency - 90%
First we need to calculate the duty cycle;
D = Vout/(Vout + Vin)
The worst case condition for inductor ripple current is at
maximum input voltage so;
D = 3.3/(3.3 + 4.5) = 0.423
Normally, the output inductor is sized to ensure that the
inductor current is continuous at minimum load and that
the output voltage ripple does not affect the circuit that
the converter is powering. In this case we will assume a
20% minimum load thus allowing a 40% peak to peak rip-
ple current in the output inductor L2.
Calculating the value of L2;
V = L di/dt
Where V is the voltage applied to the inductor, L in the
inductance, di is the inductor peak to peak ripple current
and dt is the duration the voltage is applied for. Hence;
L = V.dt/di
dt = 1/Fs x D
dt = 1/(250 x 103) x 0.423 = 1.69 μs
V = Vin during the switch ON time so;
L2 = 4.5 x (1.69 x 10-6/0.4)
L2 = 19 μH
Using the nearest preferred value would lead to the
selection of a 22 μH inductor. It is common practice to
select the same value for both input and output inductors

in SEPIC designs although when two separate parts are
being used it is not essential.
Having selected the inductance value we now need to
calculate the required RMS and peak current ratings for
both inductors.
For input inductor L1;
Irms = (Vout x Iout)/(Vin (min) * efficiency)
Irms = (3.3 x 1)/(2.8 x 0.9) = 1.31A
Ipeak = Irms + (0.5 x Iripple)
Although worst case ripple current is at maximum input
voltage the peak current is normally highest at the mini-
mum input voltage.
Iripple = (V.dt)/L
Iripple = (2.8 x 2.2 x 10-6)/22 x 10 -6 = 0.28A
Ipeak = 1.31 + 0.14 =1.45A
So a 22μH, 1.31Arms & 1.45Apk rated inductor is
required. For example the DR73-220 from Cooper
Coiltronics®, this part is 7.5mm square and 3.5mm high
with 1.62Arms and 1.67Apk current ratings.
For the output inductor L2
Irms = Iout = 1A
Iripple = (4.5 x 1.69 x 10-6)/22 x 10-6 = 0.346A
Ipeak = 1 + 0.173 = 1.173A
So a 22μH, 1Arms & 1.173Apk rated inductor is required,
which for simplicity could be the same DR73-220 inductor
used for L1.
Coupled Inductor Selection
When calculating the value for a coupled inductor you
need to bear in mind that all the current is effectively flow-
ing in one inductor and that if the two windings are close-
ly coupled the ripple current will be split equally between
them. So calculating the inductance value;
L = V.dt/di
From our earlier example the output ripple current needs
to be 0.4Apk-pk, so now we calculate for 0.8A as the
ripple current is split between the two windings
L = 4.5 x (1.69 x 10-6/0.8) = 9.5μH
From this it can be seen that by using a coupled inductor
the required inductance is halved. It is also important to
note that because the two winding are on the same core
they must be the same value. If they are not the voltage
across each winding will not be equal and Cp will act as a
short circuit to the difference.
Continuing with the example using an inductance value of
10μH we now need to calculate the worst case peak cur-
rent requirement. We already know the RMS current in
each winding,
Input inductor RMS current = 1.31A
Output inductor RMS current = 1A
Ipeak = Iin + Iout + (0.5 x Iripple)
Iripple = (2.8 x 2.2 x 10-6)/10 x 10-6 = 0.62A
Ipeak = 1.31 + 1 + 0.31 = 2.62A @ minimum input
voltage
So a 10μH coupled inductor with 2.31Arms and 2.62Apk
current ratings is required, for example DRQ74-100.
This part has the same 7.5mm square footprint as the
DR73-220 that was selected in the example using
separate inductors but is 4.35mm high.
Using a coupled inductor takes up less space on the
PCB and tends to be lower cost than two separate induc-
tors. It also offers the option to have most of the inductor
ripple current flow in either the input or the output. This is
achieved by using a winding construction that positions
most of the leakage inductance in one winding, this will
cause most of the ripple current to appear in the opposite
winding. By doing this the need for input filtering can be
minimized or the output ripple voltage can be reduced to
very low levels when supplying sensitive circuits.
Cooper Bussmann offers a number of coupled inductor
options from the Cooper Coiltronics®range, including the
SDQ and DRQ series of shielded drum inductors and the
Econo-Pac and Octa-Pac range of toroid inductors. With
inductance values from 0.33μH to 1mH and sizes from
5.2mm 2 x 1.2mm high up to 12.5mm 2 x 8mm high

PoE Power Magnetics - Options and Trends
What is Power over Ethernet technology?
Ethernet enabled devices require both data connectivity
and a power supply. Power over Ethernet (PoE) technol-
ogy allows Ethernet devices to receive power as well as
data over standard category 5 Ethernet cable. PoE is
governed by the standard defined in IEEE802.3af.
Specific details of the 802.3af standard are available
from the Institute of Electrical and Electronic Engineers
at www.ieee.org. This article highlights an easy to use,
low cost Cooper Coiltronics®PoE power magnetic selec-
tion. In short, the PoE port allows a powered device (PD)
to draw up to 12.95W from the power-sourcing equip-
ment (PSE). PSE controls the PoE port and it identifies
PDs via detection and classification before powering the
port. The big advantage of PoE is the elimination of the
nuisance “wall wart” power converters. In this case, the
need to install additional AC power outlets and connect
electrical wires to each terminal is eliminated. Only one
cable is needed for your appliance. PoE promises to cre-
ate a new world of network appliances by saving space,
lower cost, easier maintenance and flexible installation.
What is Power over Ethernet application?
PoE is gaining in popularity and manufacturers already
have products on the market such as VoIP (Voice over
Internet Protocol) telephones, UPS, Wireless LAN
access points, Bluetooth access points, Network cam-
eras, Building access systems, Time and attendance
systems, Retail point-of-information systems, Battery
chargers for mobile phones and PDAs, Vending
machines and Gaming machines.
Cooper Coiltronics Power Over Ethernet Transformer
and characteristics
In order to comply with IEEE802.3af PoE standard,
Powered Device (PD) must meet the isolation require-
ment. Dc-Dc converters solve the isolation problem.
Forward and Flyback switcher topologies can use
Cooper Coiltronics PoE transformers to isolate the PD’s
PoE interface from the rest of its circuitry while stepping
down the PoE input voltage to power the PD circuitry.
Cooper Coiltronics PoE transformers support 1500VAC
isolation in the power converter with feedback voltage of
11V at 0.1A. Available in 4W, 7W and 13W, the trans-
formers accept input voltage range from 29.5V to 60V
using a nominal 250KHz switching frequency. An EFD15
core is used in 4W and 7W transformers while an EFD17
core is used in the 13W transformers. The EFD17 is a
core developed by Cooper Bussmann to fit in between
the EFD15 and EFD20 core sizes, and allows a smaller
solution than most competitive devices for the same
output power. These components operate in ambient
temperatures between -40 and +85 degrees Celsius.
Due to the size, Cooper Coiltronics PoE transformers
can handle DC current of PoE and are rated for
operating temperatures up to 125 degrees Celsius.
Cooper Coiltronics PoE transformers feature split prima-
ry and secondary windings to minimize leakage induc-
tance – minimizing the result of imperfect magnetic link-
ing of one winding to another. These components allow
multiple output variations. 3.3V and 5V PoE transformers
support three outputs while 12V transformers support
two outputs. Each of them has same output current
and voltage. Alternately, the isolated windings can be
combined in series to produce additional voltage
combinations.
PoE13W3VERS has three different outputs, 7V, 3.3V
and 1.8V respectively. These outputs can be connected
in series to produce a converter with 1.8V, 5.1V and
12.1V from the same transformer. The series configura-
tion produces optimal cross regulation between outputs.
PoE13W2VERS has two different outputs, 5V and 3.3V.
VERS refers to the Cooper Coiltronics Versa-Pac®prod-

uct lines that offer more than 500 usable inductor or
transformer configurations. The same concept has been
used in the PoE transformer family. Connecting the
windings in parallel will increase the current carrying
capability while connecting in series will increase the
output voltage. These components provide flexibility in
the design to connect the winding in series or parallel,
and thereby achieving higher voltage or current.
Future trend- High Power over Ethernet (HPoE)
The current IEEE802.3af standard is restricted to low
power devices but the demand to standardize high
power PoE is increasing. A standard capable with double
the power limit of 13W on a 48V input was proposed.
High Power over Ethernet needs same level of safety,
reliability and should be backwards compatibility with the
IEEE 802.3af standard. Cooper Coiltronics is also
introducing 26W HPoE transformers. Due to power
and efficiency requirements, Forward converters with
synchronous
rectification are used. A gate drive winding will be
provided on the secondary side. The operating frequency
is 300KHz - available in 3.3V and 5V outputs. The new
standard delivers power to laptops, advanced network
cameras, videophone, flat screen monitor and other
high power consumption Ethernet devices.
Conclusion
With the introduction of the IEEE Power over Ethernet
standard, the advantages of easy installation and
robustness of a powered network has quickly lead to
the introduction of many new network appliances. Higher
power devices demand the same advantage, since
reducing cost is always a driver for implementing new
technology. As a key player manufacturing power
magnetics, Cooper Coiltronics offers a series of
standard PoE products suitable to use in Dc-Dc
converters. Samples are available upon request

High Current Inductors for DC-DC Converters
State-of-the-art power supply design of DC-DC
converters requires maximum thermal efficiency, low
switching losses and platform scalability. Overall systems
efficiency can be improved by the advancements in
strategic power components. When striving for maximum
efficiency, low switching components losses and parasitic
inductance losses are critical. This is driven by increasing
performance requirements of new microprocessors
ranging from 10A to120A and starting 50nH.
High current inductors can be found in many DC-DC
converter applications such as:
• VRM (Multi-phase for Servers / Desktop /
Notebook computers)
• DDR Memory Power Supply(Synchronous
Buck and Multi-phase Converters)
• GPU Graphics cards (Buck and Multi-phase
Converters)
Voltage Regulators
Multi-phase VRMs for High-End Desktops, Servers,
and Notebook Computers
The evolution of today’s microprocessors requires high
frequency synchronous buck converters to provide highly
efficient power to high current low voltage processors
with fast transient response. High frequency switching
translates back to increased FET losses as the major
contributor to switching loss. The combined DC and AC
loss in inductors is the next highest contributor of power
loss. A roadmap of modern CPU’s shows that processor
current will keep increasing up to 200Amps by 2006
(5 phases, 40A/phase). High current inductors can
positively impact the overall system’s efficiency by up
to 2%. A well packaged high current inductor: provides
higher energy density and low loss (Core and Copper
loss) and can be available in both THT and SMT which
brings flexibility to chipset developers.

Description
Cooper Bussmann’s supercapacitor solutions, using
PowerStor’s carbon aerogel technology, offer the added benefit
of customization. Application specific supercapacitors can be
designed by modifying their size and shape, ESR (Equivalent
Series Resistance), capacitance, voltage or temperature
capability.
In the portable device market, many applications are space
constrained. Using thin aluminum-polymer laminate,
supercapacitors under 1mm thick are achievable. These F
Series supercapacitors are ideal for PCMCIA cards. Traditional
cylindrical can-style A and B Series supercapacitors are
available as well as larger, very high capacitance cylindrical
and prismatic supercapacitors.
Pulse discharge capability is important for many portable or
remote applications to power transmitters, activate solenoids
or valves, assist motors or to improve the high rate discharge
capability of a low power battery system. PowerStor’s carbon
aerogel supercapacitors can be modified to achieve very low
ESR providing high rate discharge capability. In applications
where capacitance is important but ultra-low ESR is not
required, the supercapacitor can be modified to provide
higher energy density with marginally higher ESR.
A single supercapacitor has a nominal working voltage rating of
2.5V. Any application up to and including 2.5V can be operated
by a single supercapacitor, however many applications require
3.6V, 5.0V or even higher. P Series supercapacitors have been
designed for 3.6 and 5.0V applications. Custom multi-superca-
pacitor configurations are available for 12V, 24V or other
voltage ratings. Either passive or active voltage balancing
is used for all multi-supercapacitor configurations to ensure
good reliability.
Some applications require a wider temperature range than the
standard –25°C to 70°C. For these industrial or specialized
applications, supercapacitors can be designed to meet a more
severe range of –40°C to 85°C.

Application Guidelines
This document provides basic guidelines for application develop-
ment using aerogel capacitors, also known as
supercapacitors. If questions arise during your development
process and are not answered in this document, contact Cooper
Bussmann.
Lifetime
PowerStor supercapacitors have a longer lifetime than secondary
batteries, but their lifetime is not infinite. The basic end-of-life
failure mode for a supercapacitor is an increase in equivalent
series resistance (ESR) and/or a decrease in capacitance. The
actual end-of-life criteria are dependent on the application
requirements. Prolonged exposure to elevated temperatures,
high applied voltage and excessive current will lead to increased
ESR and decreased capacitance. Reducing these parameters
will lengthen the lifetime of a supercapacitor. In general,
cylindrical supercapacitors have a similar construction to
electrolytic capacitors, having a liquid electrolyte inside an
aluminum can sealed with a rubber bung. Over many years, the
supercapacitor will dry out, similar to an electrolytic capacitor,
causing high ESR and eventually end-of-life.
Voltage
Supercapacitors are rated with a nominal recommended working
or applied voltage. The values provided are set for long life at
their maximum rated temperature. If the applied voltage exceeds
this recommended voltage, the result will be reduced lifetime. If
the voltage is excessive for a prolonged time period, gas genera-
tion will occur inside the supercapacitor and may result in leak-
age or rupture of the safety vent. Short-term overvoltage can
usually be tolerated by the supercapacitor.
Polarity
PowerStor supercapacitors are designed with symmetrical elec-
trodes, meaning they are similar in composition. When a super-
capacitor is first assembled, either electrode can be designated
positive or negative. Once the supercapacitor is charged for the
first time during the 100% QA testing operation, the electrodes
become polarized. Every supercapacitor either has a negative
stripe or sign denoting polarity. Although they can be shorted to
zero volts, the electrodes maintain a very small amount of
charge. Reverse polarity is not recommended, however previ-
ously charged supercapacitors have been discharged to -2.5V
with no measurable difference in capacitance or ESR. Note: the
longer they are held charged in one direction, the more polarized
they become. If reversed charged after prolonged charging in
one direction, the life of the supercapacitor may be shortened.
Ambient Temperature
The standard temperature rating for PowerStor supercapacitors is
–25°C to 70°C. Temperature in combination with voltage can
affect the lifetime of a supercapacitor. In general, raising the
ambient temperature by 10°C will decrease the lifetime of a
supercapacitor by a factor of two. As a result, it is recommended
to use the supercapacitor at the lowest temperature possible to
decrease internal degradation and ESR increase. If this is not
possible, decreasing the applied voltage to the supercapacitor
will assist in offsetting the negative effect of the high temperature.
For instance, 85°C ambient temperature can be reached if the
applied voltage is reduced to 1.8V per supercapacitor.
At temperatures lower than normal room temperature, it is possi-
ble to apply voltages slightly higher than the recommended work-
ing voltage without significant increase in degradation and reduc-
tion in lifetime. Raising the applied voltage at low temperatures
can be useful to offset the increased ESR seen at low tempera-
tures. Increased ESR at higher temperatures is a result of per-
manent degradation / electrolyte decomposition inside the super-
capacitor. At low temperatures, however, increased ESR is only
a temporary phenomenon due to the increased viscosity of the
electrolyte and slower movement of the ions.
Operating Life vs. Temperature and Charge Voltage
The above plot shows the time taken for capacitance to drop by
30% at 1.8V & 2.5V and by 50% at 2.5V for continuous operation
at a given temperature. This can be used to estimate the operat-
ing life for specific applications where the minimum allowable
capacitance value is known.
Discharge Characteristics
Supercapacitors discharge with a sloping voltage curve. When
determining the capacitance and ESR requirements for an appli-
cation, it is important to consider both the resistive and capacitive

discharge components. In high current pulse applications, the
resistive component is the most critical. In low current, long dura-
tion applications, the capacitive discharge component is the most
critical. The formula for the voltage drop, Vdrop, during a dis-
charge at Icurrent for tseconds is:
Vdrop = I(R + t )
C
To minimize voltage drop in a pulse application, use a superca-
pacitor with low ESR (R value). To minimize voltage drop in a
low current application, use a supercapacitor with large capaci-
tance (C value).
An Aerogel Capacitor Calculator program is available online at
http://www.cooperbussmann.com for predicting electrical require-
ments and matching these requirements to various supercapaci-
tor configurations / alternatives.
Charge Methods
Supercapacitors can be charged using various methods including
constant current, constant power, constant voltage or by parallel-
ing to an energy source, i.e. battery, fuel cell, DC converter, etc.
If a supercapacitor is configured in parallel with a battery, adding
a low value resistor in series will reduce the charge current to the
supercapacitor and will increase the life of the battery. If a series
resistor is used, ensure that the voltage outputs of the superca-
pacitor are connected directly to the application and not through
the resistor, otherwise the low impedance of the supercapacitor
will be nullified. Many battery systems exhibit decreased
lifetime when exposed to high current discharge pulses.
The maximum recommended charge current, I, for a
supercapacitor where Vwis the charge voltage and Ris
the supercapacitor impedance is calculated as follows:
I=Vw
5R
Overheating of the supercapacitor can occur from continuous
overcurrent or overvoltage charging. Overheating can lead to
increased ESR, gas generation, decreased lifetime, leakage,
venting or rupture. Contact the factory if you plan to use a higher
charge current or higher voltage than specified.
Self Discharge and Leakage Current
Self discharge and leakage current as essentially the same thing
measured in different ways, due to the supercapacitor construc-
tion there is a high impedance internal current path from the
anode to the cathode. This means that in order to maintain the
charge on the capacitor a small amount of additional current is
required, during charging this is referred to as leakage current.
When the charge voltage is removed, and the capacitor is not
loaded, this additional current will discharge the supercapacitor
and is referred to as the self discharge current.
In order to get a realistic measurement of leakage or self dis-
charge current the supercapacitor must be charged for in excess
of 100 hours, this again is due to the capacitor construction. The
supercapacitor can be modeled as several capacitors connected
in parallel each with an increasing value of series resistance. The
capacitors with low values of series resistance charge quickly thus
increasing the terminal voltage to the same level as the charge
voltage. However, if the charge voltage is removed these capaci-
tors will discharge in to the parallel capacitors with higher series
resistance if they are not fully charged. The result of this being that
the terminal voltage will fall giving the impression of high self dis-
charge current. It should be noted that the higher the capacitance
value the longer it will take for the device to be fully charged, see
figure 2 in the Measurement Techniques section for more details.
Series Configurations of Supercapacitors
Individual supercapacitors are limited to 2.5V (P Series reaches
5V using two supercapacitors in series). As many applications
require higher voltages, supercapacitors can be configured in
series to increase the working voltage. It is important to ensure
that the individual voltages of any single supercapacitor do not
exceed its maximum recommended working voltage as this could
result in electrolyte decomposition, gas generation, ESR increase
and reduced lifetime.
Capacitor voltage imbalance is caused, during charge and dis-
charge, by differences in capacitance value and, in steady state,
by differences in capacitor leakage current. During charging
series connected capacitors will act as a voltage divider so higher
capacitance devices will receive greater voltage stress. For exam-
ple if two 1F capacitors are connected in series, one at +20% of
nominal capacitance the other at –20% the worst-case voltage
across the capacitors is given by:
Vcap1 =V
supply x(C
cap1 /(C
cap1 +C
cap2)
where Ccap1 has the +20% capacitance.
So for a Vsupply =5V,
Vcap1 = 5V x (1.2 / (1.2 + 0.8) = 3V
From this it can be seen that, in order to avoid exceeding the
supercapacitor surge voltage rating of 3V, the capacitance values
of series connected parts must fall in a +/-20% tolerance range.
Alternatively a suitable active voltage balancing circuit can be

Design Guides
employed to reduce voltage imbalance due to capacitance mis-
match. It should be noted that the most appropriate method of
voltage balancing will be application specific.
Passive Voltage Balancing
Passive voltage balancing uses voltage-dividing resistors in paral-
lel with each supercapacitor. This allows current to flow around
the supercapacitor at a higher voltage level into the supercapaci-
tor at the lower voltage level, thus balancing the voltage. It is
important to choose balancing resistor values that provide for
higher current flow than the anticipated leakage current of the
supercapacitors, bearing in mind that the leakage current will
increase at higher temperatures.
Passive voltage balancing is only recommended for applications
that don’t regularly charge and discharge the supercapacitor and
that can tolerate the additional load current of the balancing resis-
tors. It is suggested that the balancing resistors be selected to
give additional current flow of at least 50 times the worst-case
supercapacitor leakage current (3.3 kΩto 22 kΩdepending on
maximum operating temperature). Although higher values of bal-
ancing resistor will work in most cases they are unlikely to pro-
vide adequate protection when significantly mismatched parts
are connected in series.
Active Voltage Balancing
Active voltage balancing circuits force the voltage at the nodes of
series connected supercapacitors to be the same as a fixed ref-
erence voltage; regardless of how any voltage imbalance occurs.
As well as ensuring accurate voltage balancing active circuits typ-
ically draw much lower levels of current in steady state and only
require larger currents when the capacitor voltage goes out of
balance. These characteristics make active voltage balancing cir-
cuits ideal for applications that charge and discharge the super-
capacitors frequently as well as those with a finite energy source
such as a battery.
Reverse Voltage Protection
When series connected supercapacitors are rapidly discharged
the voltage on low capacitance value parts can potential go neg-
ative. As explained previously, this is not desirable and can
reduce the operating life of the supercapacitor. One simple way
of protecting against reverse voltage is to add a diode across the
capacitor, configured so that it is normally reverse bias. By using
a suitably rated zener diode in place of a standard diode the
supercapacitor can also be protected against overvoltage events.
Care must be taken to ensure that the diode can withstand the
available peak current from the power source.
Soldering Information
Excessive heat may cause deterioration of the electrical charac-
teristics of the aerogel supercapacitor, electrolyte leakage or an
increase in internal pressure.
Follow the specific instructions listed below.
In addition:
• Do not dip aerogel supercapacitor body into melted solder.
• Only flux the leads of the aerogel supercapacitor.
• Ensure that there is no direct contact between the sleeve of the
aerogel supercapacitor and the PC board or any other compo-
nent. Excessive solder temperature may cause sleeve to shrink
or crack.
• Avoid exposed circuit board runs under the aerogel
supercapacitor to prevent electrical shorts.
Manual Soldering
Do not touch the aerogel supercapacitor’s external sleeve with
the soldering rod or the sleeve will melt or crack. The recom-
mended temperature of the soldering rod tip is less than 260°C
(maximum: 350°C) and the soldering duration should be less
than 5 seconds. Minimize the time that the soldering iron is in
direct contact with the terminals of the aerogel supercapacitor as
excessive heating of the leads may lead to higher equivalent
series resistance (ESR).
Wave Soldering
Use a maximum preheating time of 60 seconds for PC boards
0.8 mm or thicker. Preheating temperature should
be limited to less than 100°C.
Use the following table for wave soldering on leads only:
Reflow Soldering
Do not use reflow soldering on PowerStor supercapacitors
using infrared or convection oven heating methods unless the
supercapacitor is specifically rated to withstand reflow soldering
temperatures.

Application Guidelines
Ripple Current
Although PowerStor aerogel supercapacitors have very low resis-
tance in comparison to other supercapacitors, they do have high-
er resistance than aluminum electrolytic capacitors and are more
susceptible to internal heat generation when exposed to ripple
current. Heat generation leads to
electrolyte decomposition, gas generation, increased ESR and
reduced lifetime. In order to ensure long lifetime, the maximum
ripple current recommended should not increase the surface
temperature of the supercapacitor by more
than 3°C.
Circuit Board Design
Do not design exposed circuit board runs under the
supercapacitor. An electrical short could occur if the
supercapacitor electrolyte leaked onto the circuit board.
Circuit Board Cleaning
Avoid cleaning of circuit boards, however if the circuit board must
be cleaned use static or ultrasonic immersion in a
standard circuit board cleaning fluid for no more than 5
minutes and a maximum temperature of 60°C. Afterwards thor-
oughly rinse and dry the circuit boards. In general,
treat supercapacitors in the same manner you would an
aluminum electrolytic capacitor.
Long Term Storage
Do not store supercapacitors in any of the following
environments:
• High temperature and/or high humidity
• Direct contact with water, salt water, oil or other chemicals
• Direct contact with corrosive materials, acids, alkalis, or toxic
gases
• Direct exposure to sunlight
• Dusty environment
• Environment subject to excessive shock and/or vibration
Transportation Information
PowerStor supercapacitors are non-regulated by the US DOT
(Department of Transport) and IATA. The correct international
shipping description is “Electronic Parts – Capacitors”.
Emergency Procedures
If a supercapacitor is found to be overheating or if you smell a
sweet odor, immediately disconnect any power or load to the
supercapacitor. Allow the supercapacitor to cool down, then dis-
pose of properly. Do not expose your face or hands to an over-
heating supercapacitor. Contact the factory for a Material Safety
Data Sheet if a supercapacitor leaks or vents. If exposed to elec-
trolyte:
• Skin Contact: Wash exposed area thoroughly with
soap and water.
• Eye Contact: Rinse eyes with water for 15 minutes
and seek medical attention.
• Ingestion: Drink milk/water and induce vomiting;
seek medical attention.
Note: In general the electrolyte, using the NFPA/HMIS
(0 to 4) rating system, has slight (1 out of 4) health and
fire hazard and minimal (0 out of 4) reactivity hazard.
Regulatory Information
PowerStor supercapacitors are rated non-hazardous under the
OSHA hazard communication standard (29 CFR 1910.1200)
General Safety Considerations
• Supercapacitors may vent or rupture if overcharged,
reverse charged, incinerated or heated above 150°C.
• Do not crush, mutilate, nail penetrate or disassemble.
• High case temperature (burn hazard) may result from
abuse of supercapacitor.
Disposal Procedures
PowerStor supercapacitors are non-regulated under RCRA
Waste Code. Supercapacitors may however be disposed of by a
specialized industrial waste processor or by incineration. Use
caution when incinerating as the supercapacitor can explode
unless it is crushed or punctured prior to incineration. Wear pro-
tective gear, such as face shields or goggles, coats/aprons and
gloves. Use high temperature to incinerate the supercapacitors
as the plastic (poly vinyl chloride) sleeving can produce chlorine
gas at lower incineration temperatures.

Methods for Measuring Capacitance, Inflow Current, Internal Resistance and ESR
Capacitance Measurement:
Supercapacitors exhibit considerable “dielectric absorption”
charge storage. As such, some traditional methods of
measuring capacitance may not yield accurate results when
measuring supercapacitors. A method for measuring
capacitance in supercapacitors is outlined below. This
method is recommended over others such as determining
the 63 percent voltage point and using the time in a RC
time constant calculation.
The following test circuit can be set up with a common
laboratory power supply set to the specified current and
voltage limits. The charging waveform, shown in Figure 1,
is best recorded with a digital oscilloscope. The cursor
function can be conveniently used to directly read the time
points between the 1.5 volt and 2.5 volt crossing. The
basic equation for the average current in a capacitor is:
i=C(ΔV), solving for C: C=i(Δt)
ΔtΔV
For i= 1 ampere and ΔV= 1 volt, therefore C = Δt.
Capacitance in this example is numerically equal to the time
in seconds for the capacitor to charge from 1.5V to 2.5V.
Figure 1
Because dielectric absorption is pronounced, the device
under test should be well discharged before beginning the
test to ensure consistent results. If the device has previous-
ly been charged, then its terminals should be shorted for at
least 15 minutes before beginning the test.
Inflow Current Measurement:
Since supercapacitors exhibit pronounced dielectric absorp-
tion, the measurement of actual leakage current, or self-dis-
charge current, is made difficult. When a supercapacitor is
charged to its working voltage, the inflow current exhibits
large, slowly decaying values for long times. The inflow cur-
rent is the sum of dielectric absorption current flow and
actual leakage current. Dielectric absorption current flow
represents charge going into storage, but deeply buried in
terms of possessing a very long time constant. The inflow
current as a function of time is essentially logarithmic, as
shown in Figure 2:
Figure 2
These typical curves are measured with the test circuit
below. The parts were short circuited for 2 days prior to
beginning the test. Therefore, stored dielectric absorption
charge was essentially non-existent.
Figure 3
True leakage currents, where dielectric absorption goes to
zero, take over 100 hours to reach as shown in Figure 2.
These leakage currents are on the order of only a few
microamperes. To continue to measure inflow current
beyond this point, one needs to use instrumentation capable
of accurately measuring microvolts and/or a larger resistor
value can be used in the circuit in Figure 3.
Internal Resistance and ESR (equivalent series
resistance) Measurement:
For product specification purposes ESR or AC impedance is
measured using a commercial LCR bridge at 1 kHz. This
produces a rather precise, reproducible value. Another

method is used to measure what is called the internal resis-
tance or DC impedance and can be performed with the
same instrumentation used to measure capacitance
(described above). This method produces a value for inter-
nal resistance which is not nearly as precise and repro-
ducible as the ESR measurement. However, internal resis-
tance is more directly related to device behavior in many
pulse power applications.
Shown in Figure 4 is the oscilloscope trace obtained using
the capacitance test circuit and method. An enlargement of
the beginning of the trace is shown in Figure 5. The instan-
taneous voltage step which occurs the moment the 1
ampere charging current is applied is used to calculate
internal resistance. The internal resistance or DC imped-
ance is equal to the step voltage divided by 1 ampere. For
devices which exhibit lower internal resistance than this
example, a higher constant current is required.

In this example:

impedance value is usually between 1.1 and 1.5 times the

Performing supercapacitor calculations and predicting
solutions for applications can be tedious, therefore PowerStor®
has developed an Aerogel Supercapacitor Calculator in
Microsoft Excel®. This program is available online at
http://www.cooperbussmann.com. An example of this
program is shown on the following page.
To determine the aerogel supercapacitor requirements for an
application, four key parameters are required:
•Working voltage, Vw, in Volts
• Minimum voltage, Vmin in Volts
• Average discharge current, I, in Amps
• If necessary convert power, P, in Watts to current, where
I=P/V
avg
• Discharge time, t, in seconds
Simply enter these four parameters into the calculator in step
1 and the program will calculate:
• Energy requirement, W, in Joules
• Minimum capacitance requirement, C, in Farads
• Maximum resistance, R, in Ohms
In step 2, select the operating parameters specific to the
application including whether the discharge is more similar to
a DC pulse or AC pulse at a 1kHz frequency. Next select the
operating temperature and use the "deviation from nominal
capacitance" factor to build in a safety margin, if necessary.
The program will then use these correction factors for both
capacitance and resistance throughout the remainder of the
calculations.
The pull-down menu in step 3 has a list of PowerStor superca-
pacitor products. Select the appropriate supercapacitor that
meets both the capacitance and resistance requirements from
step 1. In this step there is an option to configure supercapac-
itors in parallel and/or to force the number of supercapacitors
in series to a specific number. For example, the calculator
would recommend six 2.5V supercapacitors for an automobile
voltage of 14.4V (14.4V / 2.5V per supercapacitor = 5.76
supercapacitors, which round up to 6). In practice, increasing
the number of supercapacitors to eight in automobile applica-
tions lowers the voltage to 1.8V per supercapacitor, providing
an increased reliability margin for high temperature exposure,
with a direct result of longer life. The number of supercapaci-
tors in series (actual) can be overwritten from the calculated
value.
Confirmation of the predicted aerogel supercapacitor solution
is done in step 4. First the total capacitance and resistance
values calculated are compared to the required values. Next
the energy and hold-up time requirements are confirmed. If
the energy and hold-up time are insufficient, chose a larger
supercapacitor or increase the number of supercapacitors in
parallel. Finally, the voltage drop is confirmed. The calculated
components of resistive and capacitive discharge are summed
and compared to the maximum value allowed. If the maxi-
mum voltage drop value is exceeded, simply chose a superca-
pacitor solution with lower ESR or increase the number of
supercapacitors in parallel.
Our goal for this calculator was to assist you in finding a
solution for your design challenges. Note: this program is
only intended to predict aerogel supercapacitor solutions. All
calculated solutions should be tested in the final application.

Two major applications of aerogel supercapacitors are high
pulse power applications and short-term hold-up power.
Pulse power applications are characterized by very short,
but high current delivery to a load, i.e. during the transmit
period in a GSM mobile device. Hold-up applications are
characterized by the requirement to continue to deliver load
power for times on the order of seconds or minutes. An
example of a hold-up application is the parking of the
read/write head in a disk drive when power to the unit is
shut off. Each of these applications emphasize different
performance parameters of the device. High pulse power
applications benefit primarily from the aerogel supercapaci-
tor's low internal resistance (R), while hold-up power appli-
cations benefit from the supercapacitor's large capacitance
(C) value.
This Marketing Bulletin presents the formulae used to calcu-
late your application requirements and uses two examples
to illustrate their use. A program titled “Aerogel
Supercapacitor Calculator” designed in a Microsoft®Excel
spreadsheet is also available for your use.
Definitions
The following definitions are used in this note:
Symbol Unit of Description
Measure
C Farads Nominal capacitance value of the
aerogel supercapacitor.
R Ohms The nominal internal resistance of the
aerogel supercapacitor.
ESR Ohms Equivalent Series Resistance mea-
sured at 1 kHz.
Vwv Volts Normal or working charge voltage in
the circuit application.
Vmin Volts The minimum voltage required to
operate the device.
Iload Amps In a hold-up application this is the
average current that continues to be
delivered to the load. It is an average
as the load current will increase as the
voltage decreases from Vwv to Vmin.
t Seconds This is the required hold-up time in
the circuit, or in pulse applications,
t is the pulse duration.
Vdrop Volts The total decrease in working voltage
at the end of the discharge or high
current pulse.
Hold-Up Power Applications
An approximate calculation can estimate the value of an
aerogel supercapacitor needed in most applications. This
calculation equates the energy needed during the hold-up
period to the energy decrease in the supercapacitor, start-
ing at Vwv and ending at Vmin.
Energy needed during hold-up period: 1/2 Iload (Vwv +V
min)t
Energy decrease in supercapacitor: 1/2 C(Vwv2–Vmin2)
Therefore, the minimum capacitance value that guarantees
hold-up to Vmin (neglecting voltage drop due to IR) is:
C=I
load(Vwv +V
min)t in Farads
(Vwv2–Vmin2)
Example:
Suppose a tape drive supply is 5.0V and can operate safely
down to 3.0V. If the DC motor requires up to 2 seconds of
hold-up prior to safe shutdown at 0.5A, then the use of the
above equation predicts that the hold-up capacitor must be
at least 0.5F.
One A Series supercapacitor can supply the required
capacitance. However, the nominal operating voltage of
2.5V is exceeded by the 5V requirement. Therefore, two
aerogel supercapacitors must be configured in series. If two
equal value supercapacitors are used, then the voltage
across each device will be approximately 2.5V, which is the
nominal voltage rating.
In the data sheets the A1020-2R5105 supercapacitor is list-
ed with a nominal capacitance of 1.0F and when configured
two in series, provides 1.0F / 2 = 0.5F. Theoretically this
solution should work, but with a –20% end of the tolerance
range, this solution does not provide significant margin.
Stepping up to the next supercapacitor, the A1030-2R5155
would provide 1.5F / 2 = 0.75F at 5V. With a –20% toler-
ance, the minimum value could be as low as 1.2F / 2 = 0.6F.
This supercapacitor solution provides a sufficient safety
margin. After the high current pulse, the tape drive goes
into a very low current mode to hold up the electronics and
uses the remaining energy in the supercapacitor.
In this example, balancing the voltage across the series
combination is recommended to ensure neither device
exceeds the maximum voltage rating. See the notes on
voltage balancing in PS-5508 Application Guidelines.

Pulse Power Applications
Pulse power applications are characterized by a relatively
low value of continuous current with brief, high current
requirements. Applications have pulses that range from less
than 1 millisecond to as high as a few seconds, and the
pulse current can be orders of magnitude higher than the
continuous or background current. The duty cycle of the
pulses is usually low, typically less than 20 %.
A worst-case design analysis assumes that the aerogel
capacitor is the sole supplier of energy during the pulse. In
this case the total drop in working voltage in the circuit con-
sists of two components: the instantaneous voltage drop
due to load current supplied through the internal resistance
of the capacitor, and the drop in capacitor voltage at the end
of the pulse period. This relationship is shown in the follow-
ing equation.
Vdrop =I
load (R + t/C)
Inspection of this equation shows that the capacitor must
have low R and a high value of C if the voltage drop is to be
small.
For most pulse power applications the value of R is more
important than the value of C. This is illustrated using this
equation for the A1030-2R5155 supercapacitor. Its internal
resistance, R, can be estimated by using the DC ESR, nom-
inally 0.075 Ohms (DC ESR = AC ESR x 1.5 = 0.060 Ohms
x 1.5 = 0.090 Ohms). The specified capacitance is 1.5F.
For a 0.001 second pulse, t/C is less than 0.001 Ohms.
Even for a 0.010 second pulse, t/C is only 0.0067 Ohms.
Clearly the value of R (0.090 Ohms) dominates the outcome
of Vdrop in the equation above.
Example:
A GSM/GPRS wireless modem requires a pulse current of
up to 2A for 0.6 milliseconds every 4.6 milliseconds. Note
the pulse width doubles or quadruples with GPRS. These
modems are now available in a PCMCIA card for notebook
computers. The constraints of the notebook and the PCM-
CIA connection are an output voltage of 3.3 +/- 0.3V and a
maximum current provided by the notebook of 1A. Many
power amplifiers (PA) have a minimum voltage requirement
of 3.0V. As it is possible for a notebook computer to output
only 3.0V, the voltage to the PA must first be boosted (3.6V
is common). With a working voltage of 3.6V and a minimum
voltage of 3.0V, the allowable voltage drop due to resistance
is 0.6V.
Choosing the F Series Flat Pack FC-3R6334-R
supercapacitor yields 0.33F with 0.200 Ohms AC
impedance or 0.25 Ohms DC impedance, R. During a 2A
transmit pulse the battery provides approximately 1A and
the supercapacitor provides the remaining 1A of current.
Using the above formula, the voltage drop, IR, due to
resistance is 1A x 0.25 Ohms = 0.25V. The capacitive
component, I(t/C), is small at 0.002V compared to the
resistive voltage drop.
Conclusions
Both hold-up power applications and pulse power applica-
tions can be designed by using the simple equations pre-
sented above. When the working voltage of the circuit
exceeds the maximum operating voltage rating of the aero-
gel supercapacitor, equal value supercapacitors should be
put in series arrangement. Often, the series arrangement
should be balanced to ensure equal voltage sharing. In
pulse power applications the voltage drop across the inter-
nal resistance of the device is usually the critical factor. The
aerogel capacitor’s ultra-low internal resistance provides a
new solution to the high impedance problems characteristic
of most battery systems.

The ultimate energy storage device should have high ener-
gy density that can be released rapidly. High energy batter-
ies have been developed as single use or rechargeable sys-
tems but typically require minutes to hours to discharge, not
seconds. For high power, standard capacitors are capable
of discharging rapidly but have low energy density.
First generation supercapacitors also referred to as ultraca-
pacitors and Electrochemical Double Layer Capacitors
(EDLC), have relatively high energy density but also very
high ESR (equivalent series resistance) and are therefore
only used in very low power memory backup applications.
New aerogel supercapacitors have been developed incorpo-
rating both the high energy density of batteries (100 times
the energy of electrolytic capacitors) and the high power of
capacitors (10 to 100 times the power of batteries) as
shown in Figure 1.
Figure 1
Imagine the possible uses of a high energy, high power
energy storage device, sometimes referred to as "A solution
looking for a problem". Many engineers have and these
new supercapacitors are finding their way into a wide range
of new applications. In many instances, the supercapacitor
is the enabling technology for these new applications.
High power supercapacitors are designed similar to elec-
trolytic capacitors however supercapacitors use high surface
area carbon for accumulation of charge as opposed to the
low surface area foils in electrolytic capacitors. An electric
double layer is formed at the interface of the solid carbon
electrode and liquid electrolyte. Aerogel supercapacitors
use aerogel carbon as the active material, while the rest of
the industry typically uses activated carbon. Aerogel carbon
is known for its high level of purity, high usable surface area
and high electrical conductivity. Key features for aerogel
supercapacitors include:
• Extremely low ESR for high power and low loss during
operation
• High energy density for long run-time
• Ultra low leakage current (can hold a charge for sev-
eral weeks)
•Wide operating temperature range
• Can be cycled hundreds of thousands of times with
very fast charge and discharge rates, as opposed to
only hundreds of cycles for batteries.
Aerogel supercapacitors have reasonably high energy den-
sity compared with rechargeable batteries. In some applica-
tions, batteries have far more energy than is required, take
too long to charge, do not like to be held fully charged or
shallow discharged (NiCd memory effect) on a continuous
basis without periodic maintenance, or do not cycle long
enough. In applications such as electronic toys, UPS sys-
tems or solar charged lighting, aerogel supercapacitors
have replaced batteries as a better alternative.
Aerogel supercapacitor designs include 2.5V radial leaded
cylindrical and 5V leaded rectangular devices. There is also
a new low profile, flat pack design with thickness ranging
from 4 mm to as low as 1 mm. Large cylindrical and pris-
matic designs up to 2500F are also available.
These supercapacitors have characteristics that make them
ideal for applications in electronic circuits, portable devices
and systems powered by batteries, fuel cells or dc power
supplies. The aerogel supercapacitors can be used in appli-
cations ranging from low tech (toys) to medium tech (elec-
tronic control systems, valves and solenoids) to high tech
(microprocessor- controlled devices).
Aerogel supercapacitors provide:
• Pulse power characterized by short, high current puls-
es delivered to a load, allowing the use of a smaller
power supply or battery
• Hold-up or bridge power to a device or equipment for
seconds, minutes or days when the main power or
battery fails or when the battery is swapped out
• Main power or battery replacement
Pulse Power
A growing number of applications today require short bursts
of power, including phones, wireless modems, radio trans-
ceivers, motors, valves and solenoids. An engineer now
has two battery design options: (1) use a larger battery (or

power supply) capable of the high pulse current or (2) use a
smaller battery (or power supply) with higher energy density
(at the expense of lower power density) configured in paral-
lel with a high power supercapacitor. The second option is
known as a battery-supercapacitor hybrid configuration and
results in a high energy / high power device with smaller
size, lower weight and lower cost than the first option of a
larger battery or power supply
Pulse Power Calculations
Pulse power applications are characterized by a relatively
low value of continuous current with brief, high current
requirements. Applications have pulses that range from less
than 1 msec to as high as a few seconds, and the pulse
current can be orders of magnitude higher than the continu-
ous or background current. The duty cycle of the pulses is
usually low, typically less than 20 %.
A worst-case design analysis assumes that the aerogel
supercapacitor is the sole supplier of current during the
pulse. In this case the total drop in working voltage in the
circuit consists of two components: (1) instantaneous volt-
age drop due to the internal resistance of the supercapaci-
tor, and (2) capacitive drop during the discharge pulse.
This relationship is:
Vdrop =I
load (R + t/C)
Vdrop = Change in voltage (V)
Iload = Load current (A)
R = Internal resistance (Ohms)
t = Time (sec)
C = Capacitance (Farads)
For a small voltage drop, this equation shows that the
supercapacitor must have low R and high C. For many
pulse power applications where t is small, the value of R is
more important than the value of C. For example a lower
ESR 1.5F aerogel supercapacitor has an estimated internal
resistance of 0.060Ω. For a 0.001sec pulse, t/C is less than
0.001Ω. Even for a 0.010 sec pulse, it is only 0.007Ω.
Clearly, the value of R (0.060Ω) dominates the outcome of
Vdrop in Equation (1) for short pulse power applications.
Where t is large, 3 seconds for example, t/C = 2Ωand now
C dominates the outcome of Vdrop in Equation (1).
Ultra thin (down to 1mm), low ESR supercapacitors have
been developed for GSM / GPRS applications, including
wireless PCMCIA modems. Type II PCMCIA cards have
only 5mm inside clearance, but with a two-sided 1mm circuit
board, the supercapacitor height restriction can be as low
as 2mm. New thin supercapacitors using flexible packaging
have been developed with very low ESR. The PCMCIA
specification allows less than 1A of current to flow from the
notebook battery to the PC card but GSM / GPRS transmis-
sions requires up to 2A. GSM transmits for approximately
0.6 milliseconds every 4.6 milliseconds then runs at lower
currents for receive and standby modes in the remaining 4
milliseconds. The supercapacitor is charged by the excess
or available battery current in 4 milliseconds between the
0.6 millisecond discharges.
The GPRS protocol allows higher transmission rates with
double to quadruple transmit times of GSM. Although low
ESR is the primary design criteria to minimize the voltage
drop from the supplied voltage (3.3V) to the minimum volt-
age required for the power amplifier (3V), supercapacitors
have significantly more capacitance than other capacitor
technologies allowing the extended pulse lengths of GPRS.
An example of an application requiring more capacitance to
minimize voltage drop during a pulse discharge is digital
cameras. Low ESR supercapacitors enable alkaline batter-
ies to last longer in digital cameras. The challenge is to run
longer on fewer, low power alkaline batteries. The high
power requirement of the zoom motor causes alkaline bat-
teries to fail before they have released all of their stored
energy. Due to the relatively long (several seconds) dis-
charge pulse requirement for the zoom motor, larger capaci-
tance (6 to 10F) supercapacitors have been found to extend
the useful life of the alkaline batteries.
Figure 2 compares 2 AA alkaline batteries (top) to 2 AA
alkaline batteries connected in parallel to a single 6F super-
capacitor (bottom), without additional circuitry. To simulate
the zoom motor in a digital camera, each system was
discharged at 4 Watts for 3 seconds every 3 minutes.
This sequence resulted in 55 zoom cycles every 10,000
seconds. The voltage drop was larger for the battery (left)
compared to the hybrid (right). The battery-supercapacitor
hybrid ran approximately three times longer than the battery
alone.
Hold-up or Bridge Power
Hold-up power applications are characterized by a short,
high current or "bridge power" pulse followed by a longer,
low current drain. Standard memory backup type superca-
pacitors are capable of the low current drain but unable to
handle the short, high current pulse due to their high ESR.
During the pulse, the system voltage will drop below the
lower voltage allowed by the device’s electronics and the
system will shut down. For these applications, new low

ESR aerogel supercapacitors are capable of handling the
high current pulse to minimize the voltage drop.
Figure 2
Bridge power examples include solid-state hard drives and
portable data terminals. In the solid-state hard drive, all
memory is stored in DRAM. When main power is lost, the
information in the DRAM must be transferred to non-volatile
memory. This requires a high discharge current for a num-
ber of seconds after which the device requires a very low
current to maintain the system.
Portable data terminals use supercapacitors to "bridge"
between swapping of batteries when the device is in opera-
tion and not simply in sleep mode. Batteries can also fall
out or become temporarily disconnected if the device is
dropped. To prevent loss of data, supercapacitors are
designed to provide continuous power to the portable data
terminal until it is able to safely power down or the battery is
swapped or reconnected.
Main Power
The energy density for today’s supercapacitors has grown
substantially and is now only 3 to 10 times lower than some
rechargeable batteries (i.e. lead-acid), but with the added
benefits of nearly infinite cycle life, very short recharge
times and very high power density. Supercapacitors can be
charged directly from alkaline batteries, solar panels or
other DC power sources. As a result some portable and
remote applications are now using supercapacitors in place
of rechargeable batteries.
The toy cars and airplanes that claim "Charge In Under 10
Seconds" all use supercapacitors as the main power source
and alkaline batteries to charge them. The fast charge is
particularly important for children as their attention spans
are not long enough to wait for batteries to charge.
Solar charging is particularly important in remote applica-
tions. With 365 charge/discharge cycles per year, recharge-
able batteries require frequent replacement. These applica-
tions include remote monitoring systems, transmitters, light-
ing and traffic signs. New portable applications currently
under development include flashlights, remote controls and
radios all charged using solar power.
Another main power application that is ideal for supercapac-
itors is local area or restaurant pagers. These pagers run
for up to two hours while the patron is waiting for a table.
After being returned to the host/hostess, the pager only
requires a 10 second charge for the next customer. Nickel
cadmium batteries perform poorly in these shallow depth-of-
discharge applications due to their "memory" effect (loss of
capacity due to continuous shallow discharges). As a
result, constant battery replacement is no longer an issue or
added cost when supercapacitors designed to last the life of
the product are used for main power.
Design Considerations
Energy and Capacitance Calculations
To determine your aerogel supercapacitor requirements,
four key parameters are required:
•Working voltage, Vwv, in Volts
• Minimum voltage, Vmin, in Volts
• Average discharge current, Iload, in Amps
• (if necessary convert power, P, in Watts, to current,
Iload, where Iload = P/Vavg)
• Discharge time, t, in seconds
One can estimate the value of an aerogel supercapacitor
needed for most applications (Note 1). This calculation
equates the energy needed during the discharge period to
the energy decrease in the aerogel supercapacitor, from
Vwv to Vmin.
Energy needed for discharge:

Voltage Balancing
When the working voltage of the circuit exceeds the maxi-
mum operating voltage rating of a single supercapacitor, a
series configuration is required. Often, the series arrange-
ment requires balancing to ensure equal voltage sharing.
Either passive or active balancing can be used to maintain
similar voltages among supercapacitors where the leakage
currents may be slightly different.
Passive balancing uses equal value resistors in parallel with
the supercapacitors. Using high value resistors, small cur-
rents are allowed to flow between the supercapacitors to
maintain similar voltages. Resistors with high values result
in lower leakage currents on the order of microamperes, an
important design consideration for hybrid battery-superca-
pacitor solutions. Lower value resistors lead to higher leak-
age currents but faster voltage equilibration of mismatched
components, and can be used where the main power is
delivered by a continuous source of power (power supply or
fuel cell).
Active balancing uses a microprocessor to measure voltage
differences and open gates allowing equilibration to occur
quickly but only when needed. Active balancing does not
add significant current leakage in the final configuration, but
comes at a higher price than passive balancing. High relia-
bility applications, with higher voltages (> 5V), typically use
active balancing.
Summary
High power, high energy aerogel supercapacitors offer solu-
tions for applications by providing pulse, hold-up, or main
power.
