51 units
In the present data book, 51 units were introduced in accordance with the performance
specifications of the Law for Units in Testing Procedures, dated 26th July, 1970. The
main relations between these units and those used in previous editions of this data
book are summarized in the following:
Magnetic flux density (magnetic induction)
Previous units
1 T (Tesla) = 1 Vs/m2 = 10-4 Vs/cm 2
Decimal multiples or parts of this unit are permissible,
e.g. mT (Millitesla), 1 mT = 10 x 10- 8 Vs/cm 2
= 10 G
Magnetic field strength, magnetization
1 A/m = 10- 2 A/cm
Decimal multiples or parts can be used here, too
e.g. 1 kA/m = 103 A/m = 10 A/cm
= 1.257
X
10-2 Oe

1. Permeability
The magnetic flux density (induction) inside an inductor with a ferrite core is composed
of the magnetic flux density of the vacuum fJ.o H and the magnetic polarization J of the
ferrite:
B=f.J.oH+J
f.J.o = magnetic field constant.
Here, the so-called relative permeability or magnetic constant f.J. is introduced, defining:

(See also definitions in lEG publications 125, 205, 218, 219, 367).
'.1 Initial permeability f.J.i
The initial permeability is defined as the ratio of the variation of flux density A B to
that of the field strength A H in very weak ac fields (A H -+ 0), measured with a magnetica"y closed core (toroid). A measuring flux density of less than 0.25 mT is recommended.

'.2 Effective permeability f.J.., dimensional parameters, calculation of the air gap.
If an air gap is introduced in a magnetically closed core, e.g. a toroid or pot core, the
permeability is lower than that of the same core without air gap. This smaller permeability is due to the higher reluctance of the air gap, and is called effective permeability.
Its value depends not only on the core material but also on the shape and dimensions
of the core.

This definition is preferably used with cylindrical, tubular and screw cores where,
because of the substantial stray inductances, a clear identification either of initial or
effective permeability is not possible.
The apparent permeability f.lapp of a given core material is a function of the core shape,
the position of the winding with respect to the core, and of the coil data. A simple
comparison of the apparent permeabilities of cores made of different materials is
therefore only possible if these conditions are identical.
The apparent permeability

"'rev
When a SIFERRIT core is magnetized with a dc field H_ upon which a weak ac field
H- is superimposed, the ac field produces a small lancet-shaped hysteresis loop which
changes to a straight line as the ac field is reduced. The slope of this line is called
"reversible permeability".

Definitions
The reversible permeability I..L rev is a function of the dc magnetic bias.
It usually reaches its maximum value when the dc field strength H_ is zero. In the case
of toroids it is identical with the initial permeability !J.i'
It is not possible to determine from toroidial core data what effect the dc magnetic
bias has on other core shapes. For this reason, the magnetic bias curves are given
separately for specific core shapes.
For stability reasons, a dc bias should be avoided with high Q filter coils if possible, or
its effect should at least be sufficiently reduced by an air gap (see para. 9, disaccommodation).
1.5 Complex permeability 71
With the (relative) complex permeability Ii, the impedance Z of an inductor with
ferrite core can be described on the basis of the law of induction as follows:
Z
= jw J1 La, where La is the inductance of the inductor without the core'l.
N2 A
La = 11-0-,-·
•
On the other hand, an inductor with a ferrite core can be represented in an equivalent
circuit by a lossless self-inductance Ls connected in series with a loss resistance Rs
which is attributable only to the ferrite core material. The impedance Z can therefore
be given by:
Z

Due to the influence of the hysteresis losses (see 6.5). R s' Rp' and tan 0 depend on the
measuring field strength, but since the value for a negligibly low field strength is normally given, the loss factor includes only the remanence losses (also called the residual losses, see 6.1 ), so that:
tan 0 = tan 0,.
The variation of fl's and fl." s of our SIFERRIT materials with frequency was measured
at flux densities < 0.1 mT. For ferrite materials with higher permeability, low resistivity,
and high dielectric constant, the shape of the curve largely depends on the dimensions
of the core sample because eddy currents are allowed to be built up over the full core
cross section (volume resonance).
An example of this is shown on page 43 covering measurements at three toroids of
different heights made of a manganese zinc ferrite.
For these reasons, cores with smaller magnetic area can be used at higher frequencies.

2. Inductance factor AL
It has be"'n found useful to employ the magnetic conductance (permeance) in the calculation of the inductance or the number of turns of coils and this is called "inductance
factor AL" or "AL value". The AL value is the inductance L per unit turn
A
=
~2;
AL = !-IE ;/~o
(for measuring conditions see below).
The A value is conveniently expressed in nH = 10- 9 H. Accordingly, the inductance L
of a coil is obtained in nH from the product A . N2 •
Occasionally, the so-called turns factor c (also designated K or a) is used for determining the number of turns in accordance with the formula
N = c]/I
where L is expressed in mHo When c is expressed in 1/1/ mH and the
the conversion factor from AL to c is

value in nH,

Gapped SIFERRIT pot cores are ground to specific A values; air gap dimensions are
typical values. The A and !-Ie values given in the data sheets apply to standard coils
with defined winding data, at frequencies up to 10kHz, a flux density of fj ~ 1 mT
and without glueing and sealing. The measuring pressure should correspond to the
holding force of the mounting assemblies indicated on page 84. Care should be taken
that a good centering of both pot core halves and clean surfaces are ensured.

Definitions
3. Resistance factor AR
The resistance factor A R, or AR value, is the dc resistance Reu per unit turn, analogous
to the AL value:
Reu
AR = N 2
When the AR value and the number of turns N are given, the dc resistance Reu is equal
to AR N2 • From the winding data, etc., the AR value can be determined:

where

section of winding space in mm 2 , feu = copper factor. If these units are used in the
equation, the AR value is obtained in f.lQ = 10- 6 Q.
p
For coil formers, AR values are stated in addition to AN and IN' They are based on a
copper factor of feu = 0.5. This permits the AR value to be calculated for any copper
factor feu according to the formula

The cross section of the useful winding space, as given in the data for each coil, is
smaller than that calculated from the dimensions of the drawing. It is an empirical

wire ends are brought out and the top layer is incompletely wound.

5. Magnetization curves
5.1 Static (steady field) magnetization curves
The static magnetization curves shown on pages 51 to 57 were measured at room
temperature by the ballistic galvanometer method. Curves are also shown at a temperature of 100 °C/212 of for those materials which are frequently used at higher flux
densities.

5.3 Coercive force He and remanence B,
When a hysteresis loop is drawn in the usual manner with flux density B as the ordinate and field strength H as the abscissa, He is the field strength at which the loop cuts
the axis of the abscissa. The point where the hysteresis loop intersects the ordinate
is called the remanence B,.
5.4 Saturation flux density Bs
This is the value reached by the flux density B at high field strength. The flux densities
shown on pages 38 and 39 (material survey) are already close to the saturation point.
They were measured at a field strength of 3000 Aim. Values obtained otherwise are
marked accordingly.
6. Core losses
In SIFERRIT materials, the core loss resistance Rs (see para. 1.5) with weak magnetic
fields (up to about 2 Aim) is essentially caused by the residual loss resistance R, and
the hysteresis loss resistance Rh • Eddy currents are only of secondary importance because of the low conductivity, especially at low frequencies.
6.1 Relative loss factor
In a gapped core, the material loss factor tan 0 of the core is reduced by the factor flelPi.
The table of the material characteristics (pages 38 and 39) and the graph (page 41 )
give the loss factor as relative value Pi: tan olpi'
The effective loss factor for a gapped core is therefore:
tan (;
tan 0. = - - - P.
Pi
The residual loss resistance R, is given by
R, = w L tan 0.
6.2 Optimum frequency range
The relative loss factor tan O/Pi is plotted against the frequency for SIFERRIT materials
on page 41. These curves provide a quick reference for the selection of SIFERRIT
materials for high Q inductors. The curves of p's and pUs of the complex permeability
T1 on pages 42 to 43 are generally more suitable for designing wideband transformers
and attenuators.
25
Definitions
6.3 Upper frequency limit
'max
The upper frequency limit is that frequency at which the loss factor curve has not
yet begun to rise too steeply. This is approximately the case when the Q factor of the
toroid is about 50 or when tan a is about 0.02. The Q factor below the limit frequency
or for gapped cores is much higher.
6.4 Lower frequency limit
'min
The lower frequency limit is that frequency at which a change to the material with the
next higher permeability is recommended because of its lower losses.
6.5 Hysteresis loss resistance R h , hysteresis material constant TJe, and hysteresis core
constant TJi
If the loss resistance of an inductor with a ferrite core is measured at different flux
density levels, it is found to increase with flux density as a result of hysteresis. Since
this hysteresis loss resistance Rh can increase to differing extents in different flux density ranges and at different frequencies, measurement should be carried out at B = 1.5
and 3 mT (LIB
1.5 mT) and at
10kHz for fl.i values greater than 500, complying
with an IEC recommendation.
=
,=
If the inductance bridge can only adjust current and not voltage, a flux density of 3 mT
can be obtained for a ferrite material with fl.i = 2000 and an effective field strength
of 0.85 Aim as follows:

The material survey on page 38 shows the hysteresies material constants measured
with toroids R 10, 10 mm in diameter, at 10kHz and at the flux density inverval LIB

The magnetic characteristics indicated in this survey apply to the Rayleigh range 1). The
permissible range of modulation increases with decreasing initial permeability. Since
often the specifications of inductors do include current, inductance, and frequency
but disregard field strength and flux density, a hysteresis core constant fl.i is defined

6.6 Power loss Pv at higher flux densities
The power loss Pv of SIFERRIT materials which are useful at higher flux density levels
is shown on page 97 versus frequency, with flux density levels given as parameters
(measured with toroids R 10). The total losses versus temperature are indicated on
page 96 for materials N 27, N 41, and N 47, which are particularly suitable for power
transformers.

Definitions
where
Rv = resistance in series with inductance L,
tan OL = loss factor of complete inductor.
The measuring technique determines only inaccurately the loss components - losses
per core and losses per winding - especially for gapped pot cores. Examples are therefore given showing the Q factor versus frequency.
The so-called ISO Q curves were determined for some core types from these Q factor
versus frequency curves.
8. Influence of temperature
8.1 Curie temperature
This is the temperature at which ferrites practically lose their magnetic properties.
With SIFERRIT materials, this transition occurs fairly abruptly. The phenomenon is
reversible, i.e. when cooled to a point below Curie temperature the material becomes
magnetic again. See pages 38 and 39 for the Curie temperature of the materials.
8.2 Temperature dependance of initial permeability Jii
and relative loss factor tan O/Jii
The curves for both values versus temperature are shown on pages 44 and 45. In the
range +5 °C (+41 OF) to +55 °C (+131 OF) variation of the loss factor with temperature is of minor significance as in most cases the variation of the copper resistance
has the greater effect on the Q factor of inductors.
8.3 Temperature coefficient a of permeability
The TC value of the initial permeability is defined as follows:
a = Jii2: 1Jii1 .
-{f2-~-{f-1
Jii1 = initial permeability at temperature {f1 (20°C to 25°C) (68 of to 77 OF)
Jii2 = permeability value at temperature {f2
In a magnetic circuit with an air gap and the effective permeability Ji., the temperature
coefficient of the material is reduced by the factor Ji./ Jii' Hence, the formula for gapped
cores is
a. = a &
Jii
= Jii2 Jii1
Jii1
{f2 -
{f1
The magnitude a/Jii is the "relative temperature coefficient". It is indicated in the
material survey (page 38 and 39) throughout the range between +55 °C!131 of and
-25 °C/-13 of. The effective permeability Ji., necessary for calculating the temperature coefficient of the core, is mentioned under special core data. The diagrams on
pages 48 to 50 also show data for an extended temperature range.

Moreover, a/,ui values are also given for some temperatures in accordance with the
IEC recommendations. It should be taken into account that the temperature coefficient
of the complete inductor may largely differ from that of the core, since various parameters such as winding design, assembly (support pressure, glueing), leakage flux
ect. also determine the temperature coefficient of the complete inductor.
As far as pot cores are concerned, the a/,ui values (data on pages 48 to 50) are referred
to measurements with standard inductors at frequenaies up to 50 kHz, a flux density
B of less than and equal to 1 mT, and a measuring pressure which corresponds to the
support forces indicated on page 84.
For further information refer to the book by Kampczyk/Ross on "Ferrite cores", published
by Siemens-Verlag.
9. Disaccommodation
Disaccomodation is the variation of permeability with time under constant operating
conditions, especially at constant temperature. Tests over a period of a few years have
shown that a few hours after production the permeability of a SIFERRIT core decreases
almost linearly, if time t is plotted logarithmically. Therefore, characteristics have been
introduced:
the disaccomodation coefficient
d = ,u,l - ,u,2

Hence it follows from the indicated measuring points at tl and t2: d = 0.6% and at

Definitions
Magnetic, thermal, or mechanical stress can, once more, cause a decrease in permeability with time. The data in the material survey (page 38 and 39) is referred to a
thermal stress of at least 170 °C/338 of and is measured at times t, = 2 hours and
t2 = 20 hours after the test. Experience has shown that the value obtained by this
method is almost identical with the long-term value desired.
After a magnetic shock (value of demagnetization in an alternating field) shorter periods
of time t, and t2 can be selected than after thermal stress. After periods below 2 hours,
generally, lower values for the disaccommodation are obtained than at periods longer
than two hours.
An air gap reduces every inductance variation by the factor fl-elfl-i' It can be said that

Example:
For a pot core 22 dia x 13 of material K 1 with an effective permeability of fl-e = 15.9
(A value = 40 nH) and a disaccommodation factor DF < 35 x 10- 6 which has been
placed in operation .at a time t, = 5 weeks (after production) and which should function

, i.e. < 0.11 % can be expected.
10. Resistivity
The material survey (page 38 and 39) also provides information on the resistivity p,
measured at room temperature, low current density « 0.01 mA/mm2), and with
Indium-Gallium junctions. Higher values are normally obtained using some other types
of juncton, for example highly conductive silver.
The effect of frequency on resistivity with material N 48 is shown in the following

The effect of frequency on resistivity with highly resistive SIFERRIT materials, e.g. K 1,
is negligible.

Definitions
11. Dielectric constant
Highly conductive SIFERRIT materials exhibit a high relative dielectric constant (e r ) at
low frequencies which is based on a layer effect of the fine grain structure. At high
frequencies, all SIFERRIT materials approach the dielectric constant of the crystalline
SIFERRIT material (e approx. 10 to 20). SIFERRIT materials with a low conductivity
already display these characteristics at lower frequencies, as is shown in the following
table:

12. Magnetostriction
Linear magnetostriction is defined as the relative change in the length of a magnetic
core under the influence of a magnetic field. The greatest relative variation in length
A = ,jIll occurs at saturation magnetization. The values of the saturation magnetostriction (As) of SIFERRIT materials are given in the following table (negative values
denote contraction).

Magnetostrictive effects in SIFERRIT power transformers can produce audible whistling
similar to that in laminated iron cores, particularly when gapped U or pot cores are
used. The parts must be rigidly mounted and the use of gapped cores or the provision
of suitable spacers is recommended.

General notes on testing ferrite parts
All Siemens ferrite parts are subjected to severe quality examinations. Our quality
assurance program guarantees attaining and maintaining the required Q level throughout every stage of the formation process, i.e. from development via material procurement, production, and testing, up to delivery.
Requirements surpassing this quality level can be met by means of components complying with the CECC System of Quality Assessment. The AQL values for mechanical
and electrical characteristics, determined in this system, are particularly severe.
The Siemens ferrite products were granted this licence so that we are capable of
supplying pot cores as well as RM cores, made e.g. of the material N 48, meeting
the CECC requirements.
Primary and secondary dimensions (major and minor defects) have been determined
in accorandance with the CECC Quality Assessment system for examining the dimensions of the ferrite parts. The primary dimensions are examined lotwise with the help
of gauges, whereas the secondary dimensions are subject to less severe examinations
(see figure below). The gauges used were designed in accordance with DIN 7150,
based on a production tolerance and a compensation for wear in accordance with
01 N 7151, ISO tolerance series 8.
The following dimensions are to be understood as primary ones, illustrated with a pot
core 14 x 8, for example:

The gauge tolerance for an external diameter of 14.2 mm is e.g. 31 ,urn, i.e. parts with
an external diameter of 14.23 mm can still be evaluated as "good" (utilizing the entire
compensation for wear).

General material data
Magnetic ferrites are mixed crystals or compounds of ferromagnetic oxides (Fe20a)
respectively, with one or several oxides of bivalent metals, such as NiO, MnO, ZnO,
MgO, CuD, BaD, CoO. They have a much higher resistivity than metallic materials; the
resistivity is 10 0 to 10 5 Om compared with 10- 7 to 10- 6 Om for metallic materials.
Contrary to metallic cores, most ferrites have negligible eddy current losses in an alternating magnetic field.
Siemens ferrite cores are well-known under the trademark SIFERRIT®.

Resistance to moisture
SIFERRIT is moisture, water and also sea-water-resistant. but can be attacked by several
acids in high concentrations.
Resistance to radiation
SIFERRIT materials can be exposed without significant variation (.1 LIL ;;;; 1 % for ungapped cores) to the following radiation:
gamma quanta
quick neutrons
thermal neutrons
10 9 rad
2 x 1020 neutrons/m 2
2 x 1022 neutrons/m 2
Shrinkage due to the sintering process
The burning or sintering process produces a considerable shrinkage of the molded
body, linearly by 15 % and 40 % by volume. For this reason, often a slight distortion
must be accepted, when the cores are not worked after the burning and sintering
process. The dimensional tolerances of unworked parts are ±2 to ±3 %.

SIFERRIT Materials
Material survey
The values for SIFERRIT materials, given in the preceding table, were measured with
toroids R 10 (10 mm in diameter) and are, unless otherwise stated, related to room
temperature (23 ±3) °C/(73 ±5.4) OF.
Due to reasons of functional efficiency, that data does not generally apply to products
of deviating shape and size. Guaranteed values for the individual products are to be
found on the appropriate data sheets.

1. Ungapped pot cores
Even with the best grinding methods known today, a certain degree of roughness on
ground surfaces cannot be avoided, so that the usual term "without air gap, (ungapped)"
does not in fact imply no air gap at all. The AL values quoted allow for a certain amount
of roughness of the ground faces. The tolerance of the AL value for the ungapped pot
cores is +30 to -20% or +40 to -30%. Closer tolerances are not available for several reasons. The spreads in the AL value of an ungapped pot core practically equal
the spreads in toroids permeability, and the AL value largely depends on the grinding
quality of the matching surfaces. With increasing material permeability the influence
of the inevitable residual air gap grows larger.
The spreads in the AL value may also be increased by the mode of core assembly. Influences of mounting and glueing generally tend to diminish the AL value. It is, therefore, particularly important for delivery to keep the minimum limit value, whereas
exceeding the AL value within moderate limits (about 20%), is of no importance. Considering these versatile influences, we have made it a rule to maintain the minimum
limit in any case, whereas occasional exceeding the maximum limit will be tolerated.
2. Gapped pot cores
This type of core is used in high quality filter and resonant circuits. In case of small air
gaps (max. 0.15 mm for round types or 0.2 mm for RM cores) the air gap can be ground
into only one core .half. Then, only the half with the ground air gap has been stamped
whereas the other half is blank. The gap reduces after-effect losses, temperature
coefficient and disaccommodation factor by the ratio of the permeability of a gapped
core to the permeability of the same core without air gap, and hysteresis losses by
the square of this ratio. Furthermore, closer tolerances on the AL value can be obtained
on special order.
The rated AL values for cores with a ground air gap can be obtained from the appropriate sheets on pot cores. These also indicate the relative effective permeability f-le
used to approximately determine the loss and temperature coefficients ect. for the
appropriate effective permeability (see page 38) from the toroidal core characteristics.
In cores with a larger air gap the stray field immediately around the air gap causes
additional eddy current losses in the copper winding. If the coil Q must meet stringent
requirements, it is therefore advisable to wind several layers of polystyrene or nylon
tape instead of wire in that part of the winding in the proximity of the air gap. For
example in the section near the air gap of the center compartment of a three-compartment former, thus "padding" the winding.

gapped (s) pot or RM cores comprising 2 core halves
1 and 2, threaded part 3 and padded winding 4.

3. SIFERRIT pot and RM cores with inserted threaded sleeves
Pot and RM cores are available with threaded sleeve fitted to the core. We have developed automatic machines of high reliability in adding adhesive and in positioning the
threaded sleeve in the core.
The rigid fit of the threaded sleeve is checked regularly, at a climate of 40 °e/1 04 °FI
93 % humidity11 during four days and also by periodic examinations of 3 weeks. Bond
strengths of 20 N for 2 mm center holes (e.g. for pot cores 11 x 7 or RM 5 cores)
and> 30 N for 3 mm center holes (e.g. pot cores 14 x 8, or RM 6 cores) are greatly
exceeded, on an average of 100 N. The threaded sleeve is also properly centered and
positioned to the proper depth (this helps maintain the specified adjustment range).
Summing up, the controlled mechanical procedure guarantees higher reliability than
manual glueing and its unavoidable inadequacies.
Owing to the porosity of the ferrite, bracing of the ferrite structure because of soaked-in,
hardened adhesive cannot always be avoided. Hence, the relative temperature coefficient a/f.J. can be increased by approximately 0.2 x 10- 6 /K.
The ordering codes for pot and RM cores with glued threaded sleeve (e.g. for RM 6:
B65807 -N •••• - •••• ) are to be found on the appropriate catalog pages.
4. Inductance adjustment
Inductance curves, to 'be understood as minimum values, are included in the data for
pot core adjusting devices. The indicated percentage change in inductance is referred
to L min (inductance without adjusting screw). Adjustment is done by bridging the air
gap with a cylindrical or screw core, and is, therefore, only possible on gapped pot
cores.
In order to avoid unstable conditions of inductance, Q etc. due to intermittent magnetic
contact, the adjusting device should not come into direct contact with the wall of the
center boss during the adjusting procedure. A suitable insulator is therefore provided
for the adjustment systems of SIFERRIT pot cores.
Although wide variations of inductance can be obtained with a large air gap, it should
be remembered that the magnetic properties depend to a great extent on the size of
the air gap. If the coils have to meet stringent Q and temperature coefficient requirements etc., it is advisable to use the smallest possible adjustment range.
These conditions can be met by suitably selecting the adjusting core material (SIFERRIT
or SI RUFER). Suitable plastic adjusting tools are included on the pages dealing with
adjusting devices.

6. DC magnetic bias of pot cores and RM cores
Definitions
~
~
H_ = DC field strength in A/m
L = DC current in A
N = number of turns
Ie = effective length (in m)11
For further definitions see pages 15 to 31.
Explanations to the graphs
The curves of I-'rev = f (H_) allow an approximate calculation of the variation in AC permeability (I-'rev) and AL value due to magnetic bias. These curves are of particular interest
for pot core inductors used as transformers, since magnetic bias should be avoided if
possible with inductors to high stability requirements (filter inductors etc.). In the case
of geometrically similar pot cores, only the effective permeability of the actual pot core
in question in conjunction with the given curves suffices in determining the reversible
permeability to a close approximation.
In determining the variation of reversible permeability with magnetic bias DC field
strength H_, the effective permeability I-'e for the desired AL value is taken from the
appropriate pot core data. If the curve I-'rev = f (H_) for the actual effective permeability
is not shown, this can be obtained by interpolation from two curves shown. The
associated DC field strength H_ can be calculated from the above equation with the
effective length Ie obtained from the data.
The following curves, measured at 20 °C/68 OF and 10kHz apply to pot and RM cores
with center hole. Cores without center hole (RM 6, RM 8, RM 10, RM 12) may be
loaded by an approx. 10% higher DC field strength.
For DC magnetic bias for E cores see page 420.
Example
Pot core 26 x 16, 865671
Material SIFERRIT N 48
A = 400 nH
I-'e = 127
Ie = 37.2 mm
The decrease in permeability caused by premagnetization begins at a DC field strength
of about 1000 A/m.
This corresponds to an ampere-turns value of
'- . N
= H_
. Ie
= 1000 x 37.2
x 10- 3
= 37.2 A.

Optimum value of pot cores with dc magnetic bias. SIFERRIT material N 48
The maximum value of the inductance L rev (inductance corresponding to the reversible
permeability) or the minimum value of the dc resistance Reu which can be obtained at
a definite magnetic bias current I. are illustrated for SIFERRIT N 48 pot cores in the
following graph.
Example:
> 10 mH and Reu < 1 Q.
at 1 = 0.1 A. Lrev
Unknown: the smallest possible pot core
Solution:
All core sizes contained in a rectangle limited at the bottom by the horizontal
L 2 . Lrev = 0.1 A2 mH and atthe right by the vertical 1_ 2 . Reu = 0.01 Ware possibilities. Therefore. the size of the smallest possible pot core is 22 mm dia x
13 mm with AL = 1000 nH. Reu approx. 0.86Q, Lrev approx. 10.6 mH and N =
VReuiAR approx. 114, 1 section coil former.

7. Typical calculation of a resonant circuit inductor
A SIFERRIT pot core inductor is required with an inductance of 640 JiH and a minimum
1
-3
Q of 400 (tan (\ = Q = 2.5 x 10 ) for a frequency of 500 kHz. The temperature coefficient a e of this inductor should be 100 x 10-6/K in the temperature range 5 to 55 °CI
41 to 131 of.
a) Choice of material
According to the material survey on pages 38 and 39, and the curves tan O/f.li on page
41 the material M 33 for example, can be used for 500 kHz.
b) Choice of
A
value
The Q and temperature coefficient requirements demand a gapped pot core. The
average relative temperature coefficient a/f.li of SIFERRIT M 33 according to the
material survey is 1.6 x 10-6/K. Since the required ae value of the gapped core should
be about 100 x 10-6/K, the effective permeability is:

c) Choice of winding material
Single silk covered, high frequency litz wire 20 x 0.05 inc!. single natural silk covering
(or 43/44 in AWG) is particularly suitable for frequencies around 500 kHz. The approximate overall diameter of the wire including insulation, say 0.367 mm (14 mils), and
the average resistance per meter of say 0.444 Q/m are obtained from the litz table
(page 63). It is recommended that the actual overall diameter always be measured,
and this value used for the calculation.
d) Number of turns and type of core
For an AL value of 100 nH and an inductance of 640 f.lH the nomogram on page 74
shows that the number of turns required is approximately 80. The nomogram for
formers on page 66 shows that for a wire with an external diameter of 0.367 mm the
two-section former for core type 18 x 11 (865651) can easily take 80 turns. This type
can therefore be used with a two-section former.
e) Length of wire and dc resistance
The length of an average turn IN on the above former is 35.6 mm (see page 165). The
length of litz necessary for the coil is therefore 80 x 35.6 = 2848 mm plus say 2 x 10 cm
'for the connections, giving a total length of 3.04 m. The average resistance of this wire
is 0.444 Qlm; the total dc resistance Reu is thus 3.04 m x 0.444 Q/m approx. 1.35 Q.
It should be noted that the length of an average turn IN given in the table always
refers to the fully wound former; an appropriate correction must be made where
necessary.
81
Inductor Design
f) Quality test
The mathematical calculation of the total loss, i.e. the loss from the core and windings,
is very laborious and only approximate. At the specified frequency of 500 kHz considerable dielectric and eddy current losses occur in the winding. Q is therefore checked on
a sample coil wound as specified above, in this case the value being about 550 as
shown in the graphs on page 174.
g) Checking the temperature coefficient
Pot core 18 x 11 with A = 100 nH has an effective permeability Po of about 47.9
SIFERRIT M 33 has a relative temperature coefficient a/pi of approx. 1.6 x 10- 6 /K;
therefore the following temperature coefficient can be calculated:
flo
= Po·
a/pi
= 47.9
(1.6 x 1O-6 /K)
= 76.5
x 1O- 6 /K;
Actual measurement showed 90 x 10-6 /K;
It must be pointed out here that when the magnetic flux lies almost entirely within
the core, the temperature coefficient is only reduced slightly.
For effective permeabilities Po < 80, however, due to the influence of the winding an
additional temperature coefficient of approx. (10 to 30) x 10- 6 /K has to be included
in the calculation.
' .'
8. Assembly of inductors
Every pot core should always be used with its associated mounting assembly. The
fixing parts are vibration-resistant. The pressure of the spring jig or the clamps is only
exerteQ on the side wall of the pot core and .not its middle part in order to prevent
the sensitive'air gap in the center stud from being affected.
Despite the reliable fixing, the pot core halves should also be glued, especially when
gapped pot cores are used for resonant circuits, since the pot core halves can move
slightly when subjected to strong vibration thus entailing undesired inductance changes.
8.1 Glueing of the core halves
From the numerous adhesives, epoxy resins with appropriate hardeners have proved
particularly suitable, for example:
8.1.1 Adhesive preparation
A) for cores
100 g Araldite A Y 103
16 g hardener HY 956
max. pot life 1 hour
hardening: 6 hours at 70 °C!158 OF
temperature stability of the glued
joint 70 °C/158 OF
(for a short period 90 °C!194 OF)
82
B) for cores
100 g Araldite A Y 103
7 g hardener HY 992
approx. pot life 8 hours
hardening: 6 hours at 100 °C/212 OF
temperature stability of the glued
joint 90 °C!194 OF
(for a short period 120 °C/248 OF)
Inductor Design
C) for coil formers
100 g adhesive A
200 cm 3 filler Aerosil 200
hardening procedure like A
D) for threaded sleeves of adjusting
devices and for external glueing
100 g adhesive Araldite AW 134 B
40 g hardener HY 994
max. pot life 1 hour
hardening procedure for 24 hours
at 25 °C/77 OF
or 4 hours at 70 °C/158 OF
temperature stability of the glued
joint 80 °C/176 OF
(for a short perioa 100 °C/21 2 OF)
Adhesive A hardens even at room temperature, higher strength can be obtained with
a hardening temperature of 70 °C/158 OF. Adhesive B only hardens at higher temperatures, with the advantage of a longer pot life, but its fluidity is higher than that of
type A adhesives.
8.1.2 Cleaning and degreasing the pot cores
The mating surfaces must be free of dust, fat, and fibers. To degrease the mating surfaces a non-fluffy nylon coated stamp pad soaked in trichlorethylene can be used.
A second pad can then be used to dry the surfaces. Any remanents impair the adhesion.
To improve the evaporation of the trichlor the cores can be heated by suction up to
about 35 °C/95 OF.
8.1.3 Applying the adhesive and glueing the halves together
The adhesive A or B is dabbed two to four times on the cleaned surface of the pot
core side wall, but the center boss must remain clean. The two core halves without coil
former are then placed on a mandrel and rotated against each other two or three times
to spread the adhesive. A slight ring of adhesive extended around the edges indicates
sufficient adhesive has been applied.
The adhesive should be applied and spread twice on the somewhat porous, low permeability SIFERRIT materials (U and K types). The next step should follow immediately,
since the adhesive film easily attracts dust and absorbs moisture. Therefore, the pot
core pair with adhesive already applied must be opened for a short period and then
the wound coil inserted without touching the mating surface.
The wound coil is then fixed in position by elasticized spacers, which must be inserted
before the adhesive has been applied.
The spacers are available upon request.
The coil former can also be fixed by an adhesive solution (C). which should only be
applied as spots in one position of the pot core bottom, to prevent any mechanical
stresses between the plastic and the ferrite material because of their different thermal
expansion. Adhesive D is also suitable for external glueing, i.e. only four cementing
spots at the joints on both sides of the openings. Because of the somewhat lower
torsional strength, it should be noted that this kind of glueing should be used with
mounted cores.
83
Inductor Design
8.1.4 Holding jigs
The pot core assembly is cured under pressure in a centering jig. The pot core holes
are used for centering and from two to eight can be held in one jig with a pressure
spring. Spacers will ensure that the pressure is exerted only on the side wall of the
pot core. Single jigs make the core inductance measurements easier. This technique has
proved useful to control the pot cores, particularly those with small air gaps, before
the adhesive has hardened. Small inductance corrections can be made by slightly turning the pot core halves relative to each other.
When pot core sets already mounted in the mounting assembly are to be cured, a good
centering, possibly by mandrels with stepped diameters must be ensured. Furthermore, care should be taken that no hardener remains on parts of the mounting assembly.
The devices should exert approximately the following pressure forces, corresponding to
the holding forces of the listed mounting assemblies and clamps (per pair of clamps):

8.1.5 Curing the assembled pot core
The curing process is more effective at an increased temperature even for adhesive
for example at 70 °C/158 of for 6 hours.
A.
The cores should be placed quickly in the oven after the adhesive has been applied to
prevent the adhesive from soaking into the porous ferrite material. The cores can be
moved into and also removed from the warm oven (e.g. 70 °C/158 OF), however the
holding jig should not be opened until the assembly has cooled down. With regard to
the thermal expansion of the ferrite, its temperature change should not exceed approximately 1 K/min.
8.1.6 Thermal after-treatment
Any internal stresses can be relieved by subjecting the assembled pot core to a temperature cycle up to 70 °Cj158 of (cycle time 24 hours) with a slow warm up and cooling,
lasting for a period of about 4 hours. The cycle should be best performed with completely mounted pot core inductors (including adjusting device when necessary).

Inductor Design
8.2 Dip soldering of coil formers for all types with injection-molded pins
During dip soldering, care should be taken that only 2 to 3 turns of the wire are dipped
into the tin bath (see * in the drawing) and soldered. Depending on the thickness of
the wire more turns may have to be wrapped around the pin.
These limiting immersion depth prevents the solder pins from being heated up close
to the pin embedding, moreover, formation of solder jumpers between the wire ends
is avoided. Prior to every dip soldering process the oxide film has to be removed from
the surface of the tin bath.
8.3 Glueing of threaded sleeves for adjusting screws
Pot cores are available in which the threaded sleeve has already been glued in position
(for ordering codes see the appropriate pages dealing with pot cores).
For 9 and 11 mm cores a thread for the adjusting screw is provided in the base plate
of the mounting assembly.
A centering jig is necessary to press the flangeless threaded sleeve in the pot core
hole, whereas threaded sleeves with a flange can be centered more easily. It is recommended to glue these sleeves in position without exception, especially because of
expansion during large temperature changes. The adhesive D stated in para. 8.1.1 can
be used. The threaded sleeves with a flange should be painted with adhesive on the
inside ring.
The flangeless sleeves with spring crown type B65579-K 1 can centrally be located
in a less complicated way, however care should be taken to prevent the adhesive from
flowing into the thread. Therefore, the pot cores should be located with their threaded
parts downward during the curing period.
The threaded sleeves must be cured for at least 24 hours at room temperature, and
it has been found practical to utilize the 24 hours waiting period between curing
and thermal after-treatment.
8.4 Final adjustment
After each thermal or mechanical stress disaccommodation arises. The complete coils
should therefore be stored for at least one day or better a week, before they are finally
adjusted.

Cores for High Power
Cores for High Power
General
In order to meet the versatile requirements of power electronics, special ferrite core
types have continually been added to the range of conventional ferrite cores. It is this
comprehensive range which enables satisfactory solutions even of unusual tasks. At
the same time, new materials such as N 41 (of high permeability, for applications with
biasing) and N 47 (for frequencies greater than 200 kHz) were added to the SIFERRIT
material N 27 proven for applications in power electronics.
Materials
N 27. N 41:
N 47
10 kHz to 100 kHz (200 kHz)
200 kHz to 1 MHz
Apart from the more favorable biasing characteristics of N 41 thanks to its higher
permeability; the materials N 41 and N 27 are comparable. At present, the application
range preferably covers up to approx. 50 kHz, whereas more recently applications up
to 100 kHz and 200 kHz are also included.
State-of-the-art power supply units even operate at frequencies above 200 kHz. For
this, our new material N 47, featuring favorable characteristics for power applications
up to approx. 1 MHz, is provided.
The main data for material selection is shown in the following illustrations. More detailed information can be obtained from the material survey on page 38/39 and appropriate curves shown on the following pages.

Core shapes
RM cores
The worldwide used RM cores are standardized in the IEC publication 431 A, B.
Recently, program-controlled winding machines for the production of coil formers
are available. For RM 6'1, 8, 10, 12, and 14 cores, we additionally offer coil formers
with a greater pin spacing. This is advantageous for the connection of thicker litz wires
which are necessary to meet higher frequency requirements.

PM cores
These cores are used where power iii the range between 250 Wand approx. 2 kW
has to be transmitted. Due to their large effective magnetic area, they need only a few
number of turns; leakage inductance and self-capacitance are low. Good screening is
obtained as a result of the compact design. If connection on the PCB by means of the
pins becomes impossible due to the weight, the coil former can be mounted with its
pins upwards.

The EC cores meeting the IEC standard permit large winding space and good lead
connection. They can be mounted horizontally or vertically. Holding devices are available for both versions.
ER cores are of similar design, i.e. with round center leg. This round center leg enables
compact windings. An 18 pin coil former is available for the ER 42/15 type.

CC cores
C cores (cup) are especially used for crossover networks in speaker systems. Together
with the cap (CC cores) and a relatively large air gap, they are well suited for energy
storage chokes. It should be mentioned that the contact surfaces are not ground. Thus,
air gap and inductance may have somewhat greater tolerances.

Figure 2
Transmissible power P and volume V of transformers with N 27 and N 41 SIFERRIT cores at high frequencies
(approx. values)
The plotted core shapes generally meet the requirements of that frequency range. As
today's switched-mode power supplies preferably operate at increasing frequencies,
enhanced importance is attached to that frequency range. Thanks to the particular
characterics of RM cores (completed by some EC and PM types), their standardized
compact design, as well as the suitability of coil formers for automatic winding machines, they are particularly suitable for use throughout the frequency range between
50 and 100 kHz.
99
Cores for High Power
The frequency range above 100 kHz is becoming more and more important for power
supply units. For this reason, the material N 47 has been developed. The transmissible
power for RM 5, RM 6, RM 8, and RM 10 cores, made of this material, is shown in
figure 3 for frequencies of 300 and 600 kHz (single-phase feedthrough and pushpull feedthrough converters).

Design of power transformers
The transmissible power P of transformers can be calculated in close approximation
with the aid of the following equation:
P = C . f· t:;8 . S . feu· AN . Ae
(1 )
This simple equation neglects voltage drops at the winding resistances, leakage inductances, as well as the magnetizing current of single-phase feedthrough converters.
The constant C takes the operation mode into consideration, i.e.
C = 1 in push-pull feedthrough operation
C
=
2
~;
p
i.e. C = 0.71 at the switching ratio p = t1 . f
in single-phase feedthrough operation and
= 0.5
C = 0.61 in (single-phase) blocking operation
Further quantities in equation (1) are: switching frequency f, deviated magnetic flux
density t:;8, current density S, copper factor feu, winding cross section AN' and effective
area A e .
The deviation in magnetic flux density t:;8 is limited by the permissible heating t:;i7 Fe of
the core resulting from core losses and saturation phenomena which are due to the
material used. It should, furthermore, be taken into consideration that the flux density
in a core of unequal cross sections has to be designed according to the minimum
core cross section A min , since due to the flux concentration, the highest flux density is
to be found in this area. Hence it follows:
(2)
The smallest flux density deviation which has been determined according to the limitations mentioned above, is the flux density deviation /J.8, found for equation (1). The
current density S is limited by the heating of the winding due to copper losses. The
characteristic curves, plotted in the figures, are based on these considerations.
More detailed information including design examples can be obtained from the offprint 8/1967-101.
Comment on
Amin
In addition to the effective area A e, used for dimensioning at low excitation, the min.
core cross section Amin is indicated for cores for power transformers with differing
cross sections along the magnetic path.
In case of large excitations (approx. > 100 mT), the flux density should always be
referred to A min , as the smallest core cross section is mandatory for magnetic saturation and core heating. The data on Pv and f.1.e was subject to corresponding considerations.

Cores for High Power
Design fundamentals for energy storage chokes'l
The most important aspects for designing energy storage chokes are briefly explained,
taking the most usual switched-mode power supply - step-down mode - as an example
(figure 4).

If the response of the choke voltage UL is of rectangular waveform, that of the choke
current IL will have a sawtooth waveform (figure 2):
• t

Schematic for voltage UL and
current IL of energy storage chokes
Depending on the current ripple b'/L - for step-down SMPS generally below 0.3 IL .
the maximum choke current I Lmax = IL + 0.5 t::,./L•
The maximum magnetic biasing capability (PL)max of the core is obtained at optimum
design, whereby the inductance - under worst conditions (at maximum operating
temperature) - may decrease by 5 % at the most. The inductance for the step-down
SMPS is calculated as follows:
L = (Ui - Uo) Uo
t::,./L • f· Ui
with the given operating conditions Ui =,input voltage, Uo = output voltage, f = switching frequency. As soon as the maximum magnetic biasing capability has been found
out with the aid of ILmax and L, core type, core size, and air gap can be determined.
With increasing air gap, the magnetic biasing capability rises, but also the pertinent
copper loss PR and hence the heating of the choke. An optimum gapping is attained
when the overtemperature t::,.n just reaches the permissible value.
11
For detailed information, the off-print 8/1967-101 is recommended.
102
Cores for High Power
The relationship between magnetic biasing capability (PL)max, copper loss PR, effective
permeability fJ.e (effect of air gap), and overtemperature .6.~ between 30 and 50 K is
shown in the nomograms of figure 6 for three different core series. Core losses due to
ripple have not been taken into consideration. Type, size, and air gap can be chosen
with the help of these nomograms.
Example
CC cores
Given: (PL)max = 8 A2 mH and t.i1 approx.
40 K
CC50
Required: Ferrite core and 1'.
~.,/
,
Solution: An effective permeability 1'. of approximately 38 can be obtained from the nomogram in the center of figure 3 on the rising
straight line of the EC41 core in the height of
the ordinate 8 A2 mH and in the middle of the
plotted temperature range between 30 and
50 K.

Pot Cores
Pot Cores
Pot cores, general
Pot cores complying with DIN 41 293, IEC 133, have a low stray field due to their
closed form. They feature high Q and high stability along with very fine adjustment
capability. In the course of time they have practically penetrated the entire electrotechnical field. To meet the large application field, a comprehensive type spectrum with
accessories is at the user's disposal. Standardized pot cores are to be preferred. Most
of the types are available with inserted sleeves.
Coil formers with mounted pins are intended to be used for four-slot pot cores as well
as for IT cores which are particularly suitable for touch tone telephone systems (see
sections "4-Slot Pot Cores" and 'Touch-Tone Pot Cores").

material (e. g. silicone rubbers 3144 RTV of Messrs. Dow Corning) onto the drum core thread in
order to eliminate its play. Then, the associated cup core is screwed on. Subsequent adjusting of
the inductor by turning the cup core is possible at any time.

RM Cores
RM Cores
RM cores for inductors and transformers, general
The demand for coil formers with directly attached terminal pins for the windings
gave rise to the development of compact RM cores. Compared with round pot cores,
the pins at the coil former require larger openings in the cores, thus ensuring an
efficient winding method.
During assembly, RM cores - in addition to being well glued as recommended - are
held together by means of clamps which engage in recesses in the base. The dimensions of the RM cores are matched to the hole arrangement of the printed circuit.
RM 6 means, for example, that the core with coil former fills a square basic area of
6 x 6 modules = ·15 x 15 mm 2 • The sizes which are mainly used, RM 4 to RM 14,
are specified in IEC publication 431/431 A, DIN 41980, and the coil formers in
DIN 41981.

General
In power electronics, transformers are increasingly used for handling high powers in the medium
and high frequency range, not only in switched-mode power supplies and other forms of dc/de
converters. For numerous design tasks in telecommunications and industrial electronics (e.g.
power pulse transformers in radar transmitters, antenna matching networks, machine control
systems, thyristor firing transformers and others), the pot core shape offers various advantages:
wide flux area for high power at a minimum number of turns, thus causing only low magnetic
leakage and stray capacitance; the closed form provides good shielding and precisely ground
air gaps, moreover, straightforward assembly and economic mounting.
A family of large pot cores, briefly designated "PM" cores (for Pot core Module) are introduced
in the following.
Due to the weight of the fully wound transformer choke, mounting on usual PC boards may in
some cases require additional mechanical support, particularly if a large core, such as that of
87 mm dia., is used. In such cases, the coil former should be mounted with its terminals upwards
(refer to figure 2). Depending on the kind of equipment, the terminals may be solder tags or
plug-in sleeves as flat plug terminals. Coil formers with AMP plugs, for example, are particularly
recommended at high currents or for thick leads.
345
B 65646
PM Cores 50 x 39
PM cores complying with DIN 41 989 (at present only draft)
Owing to their large apertures for bringing out the leads, these cores are particularly suitable for

Pot Cores for Proximity Switches
Pot Cores for Proximity Switches
General
It is the proximity switch which permits contactless handling of motions and switching functions.
Application examples are: logging of the final position of conveyer belts, counting facilities at
rotary parts, powerless sensing of indicating instruments in measuring and control technique.
In addition to bouncefree switching and resistance to mechanical wear - the decisive advantages
of all contactless switches - inductive switches, moreover, feature insensitivity to contamination
and recognition of metallic parts.
Pot cores and coil formers
A series of pot cores with diameters between 5.6 and 70 mm is available for inductive proximity
switches. Their dimensions comply with the CENELEC draft standard EN 50008. Maximum response
distances can thus be achieved for the various pot core sizes. The SIFERRIT material N22 is particularly suitable for applications in the main frequency range between 100 kHz and 1 MHz. The
SIFERRIT material M33 is available for higher frequencies, meeting the small pot core sizes 5.6 mm
dia. to 9.0 mm. For the port core sizes 7 mm dia. to 70 mm matching thermoplastic coil formers
can be delivered. The operating temperature range of these coil formers covers -60°C to
+120 °C/-76 of to +248 of. During the potting process, the temperature may not exceed
120 °C/248 OF.

E, EF, EC, and ER Cores
General
For "definitions and symbols", for "SIFERRIT materials", and "coil design" refer to
page 15 ff.
1. Core shape and material
E cores are made of the SIFERRIT materials N 27 and N 30. They are available with
or without a ground air gap.
The types specified on the following pages comprise E cores (DIN 41 295) with dimensions according to the laminations type M (DIN 41 302), and EF cores (DIN 41 985)
with dimensions according to laminations type EE (DIN 41 302). The cores manufactured in material N 27, feature high saturation magnetization and low power loss. They
are particularly suitable for use in dc converters in electronic flash devices, voltage
converters in switched-mode power supplies, and in transducers, e.g. for pincushion
correction of for control transducers in the thyristorized line output stages of color TV
sets (refer also to data in the chapter: "Cores for High Power", page 89).
Core EI 25 (DIN 41 986) is usually made of the SIFERRIT material N 41.
Because of its high magnetization and its low temperature dependance up to 100 °C/
212 of together with a remarkably high permeability, this material is particularly suitable for variable inductances by dc premagnetization (current-controlled transducers).
For details refer to the appropriate data sheet, page 431.
2. Ordering and delivery
E cores are delivered individually (not as sets). The indicated packaging units (PU)
should be taken into consideration. Each packaging unit only contains cores of uniform design, either with shortened or with unshortened center leg. The nominal AL value, quoted in the individual data sheet, always refers to a combination of the ordered
core with a core with unshortened center leg (dimension "g" = 0).
The curve "AL versus total air gap", specified in the individual data sheets, aids the
designer in choosing additional AL values by appropriate combinations of gapped
cores.
3. Ungapped E cores
Even with the best grinding methods known today, a certain degree of roughness on
ground surfaces cannot be avoided, thus, the usual term "ungapped" does not in fact
imply no air gap at all. In the AL values specified, a certain amount of roughness of
grinding, e.g. R, 6 ~ 6 pm, has been taken into account for the gaps. The AL value
tolerance of ungapped E cores is
=~g%,
that of EC cores approx. ±25%.
4. Winding design
A nomogram for the number of turns, inductance, and AL values is given on page 74
to 76; the data for the usual normal and litz wires is tabulated on page 63 to 65.
The maximum number of turns for coil formers are indicated on page 73, 74, and data
on winding cross sections and average lengths of turns on the appropriate pages on
coil formers.
417
E, EF, EC, and ER Cores
Note for the winding design
If coil formers are used for cores with square or rectangular cross sections, indication
of the minimum winding height only represents a theoretical value. The use of thicker
leads or litz wires results in a gradual rounding of the winding; it is thus recommended to verify the planned winding design by a winding test.
5. Effective magnetic characteristics
For the values of E IfA. I., A., A min, V. (applying to E core sets) required for calculation
of field strength, flux density, and hysteresis losses refer to the core types.

7. Comparison between E cores and pot cores
Generally, pot cores are preferred to E cores due to their smaller space requirements,
better shielding, and simpler mounting. The following diagram gives a comparison
between both core types, each of SIFERRIT N 27 and N 30 (ungapped).
The reciprocal dc time constant Rcu/L (see page 24) which - as is generally known should be as low as possible for a coil, is plotted against the volume.
Here, the following core volumes apply:
for E cores:
the square described about the E core set and the coil former (without fixing parts)
for pot cores: the square described about the pot core set (without fixing parts).
Single section, fully wound coil formers are used as a basis; a copper factor fcu of 0.5
is assumed for the winding.
1 Reciprocal dc time constant (typ. values) versus volume
5 (size comparison between some pot and E cores for N 27 and N 30 materials).

EC Cores
General
These E cores with round center leg provide a large space for the windings and permit even thick wires to be brought out conveniently. Owing to the large width for the
winding good coupling between the windings is obtained. Coil formers with solder
tags for vertical or horizontal magnetic axes are available.
EC 35, magnetic axis horizontal
EC41,EC52
magnetic axis vertical
EC 41, EC 52, EC 70
magnetic axis horizontal
EC 70, magnetic axis vertical
Coil formers for EC cores
The coil formers, made of glass-fiber reinforced polyterephthalate, are flame-retardant
in accordance with UL 94 V-O. They are available for the EC 35 core as horizontal
version, for the EC 41, 52, and 70 cores also as vertical version with differing numbers
of terminals (see following pages). Operating temperature range: between -60 °C/
-76 OF and +120 °C/+248 OF.

U and UI Cores
Figure 1
General
By virtue of their high saturation flux density level, high Curie temperature, and low
power losses, U and UI cores made of SIFERRIT N 27 are suitable for use in power,
pulse, and high-voltage transformers, e.g. in line deflection transformers for blackand-white and color TV, in energy storage chokes, ignition transformers, etc.
Relevant SIFERRIT material data and general information on power dissipation and
amplitude permeability versus temperature, magnetic flux density, and frequency may
be obtained from the materials survey and from the following curves.
Power transformers with UI and UU cores
For transformers with high power ratings (> 1 kW) we manufacture U and I cores of
rectangular section which can be combined in various ways like building blocks to
form UU cores of larger cross-section or EE-shapes that are suitable for transformers
in the kilowatt range (fig. 2).

Toroids
From this equation one obtains fJp as permeability determined by flux density and field strength
deviations at pulse operation. The magnetizing current pulse - shown in fig. 2 - has in its initial
and final part a current step, generated by the core losses, and an inductive current step im - iR
with an approx. linearly rising characteristic.
Since in many cases the current step iR cali be neglected for pulse permeability calculations, the
peak value of the magnetizing current im can be introduced as the current difference ,1; when the
field strength deviaton ,1H should be calculated.
When the value of ,18 increases, mainly at higher pulse repetition frequencies and an increasing
pulse duty factor, the current step iR - as a proportion of the total current - may be of greater
importance.
Figure 5 shows, therefore, fJp 0.2 referred to a flux density ,18 during the interval td - 0.2 td and
an accordingly increasing magnetizing current ,1i = im - iO.2 td (disregarding the current step at
the beginning of the pulse).
Test conditions
Figure 3 Measuring circuit
For a specified material, the pulse permeability depends upon the flux density deviation, the
pulse repetition frequency, and the core temperature. Preferred test operation conditions are as
follows:
fj
= 25 °C/77 of
10 kHz
1 fJs
100 kHz
1 fJs
1 MHz
0.5 fJs
The time constant of the circuit (figure 3) has been determined such that the pulse current of
the preceding pulse has approximately decayed to zero when the next pulse starts to rise. The
resistance Rd causes the voltage peak value to decrease when the current has been disconnected.
The core heating mainly depends on the heat conductive medium, e.g. copper winding, mounting,
encapsulation etc. The data in the test curve for continuous operation and short term measure,ment refers to 6.3 mm diameter toroids with N approx. 20/CuL, freely suspended.

Example
The required secondary pulses must have an amplitude 12 = 120 mA. a duration td = 0.5 f.Js,
and a maximum tilt of p = 5 %. The terminating resistance R2 is 50 n, the source resistance R,
= 200 n and the turns ratio n = 2 : 1. The maximum core temperature is 70 °C!158 OF.
(Definitions in accordance with DIN 41 284).
The provided material is SIFERRIT N 30.
Equation (1) yields R = 100 n, equation (2) Lp = 1000 flH and equation (3) K = 6.0 flVS and
hence Lpl K = 167 flHilNs. From the nomogram one obtains N' = 85 cm-'. As shown in figure 4,
a permeability fl of approx. 1800 can be assumed for SIFERRIT N 30 at td = 0.5 f.Js. Equation (4)
yields V. = 0.006 cm 3 , i.e. the toroid R 4 having a V. = 12.3 mm 3 can be chosen. N, = 58 is calculated form equation (5). The magnetic field constant f.Jo = 4 l' . 10- 9 Vs/Acm.
Hence the transformer can be designed as follows:
SIFERRIT toroidal core R 4, of N 30 material, N,
474
= 58,
N2
= 29.

Damping Pearls
B 62110
Damping pearls are made of SIFERRIT N 22 and are suitable for use in the short-wave range as
well as up to the ultrashort-wave range.
Slipped over a conductor, the pearls generate a damping effect, which increases with the number
of pearls. Premagnetization of the pearls reduces the damping effect.

Frequently, there are certain cases of application, which require plate- or quad-shaped ferrite
parts. To meet this requirement, cores, preferably made of SIFERRIT N 22, (quantity upon request)
are available in the following sizes. (The deviation of unground cores may be up to 1 % of their
length).

Apart from adjustable inductors as used for IF filter coils, filters for oscillator circuits,
ect., fixed inductors are also applied in electronic equipment in order to suppress undesired RF interference. The frequency range of such choke coils approximately covers
10 3 to 10 B Hz. In most cases, the basic shapes include cylindrical cores featuring a
single layer winding and axial leads. Cores with side flanges (yarn roller core) which
can be wound in multilayer construction are in particular available for higher inductance values.
