Calculating Method of Winding Turns Condition: Core:NS229125 AL=90 nH/N2 Required Inductance: 44H�8%
�8%AL82.8 ~ 97.2 nH/N2
Calculation process AL tolerance is �8%, AL range is from 82.8 to 97.2. Difference winding turns must be considered in order to receive the same inductance when using difference AL core. We can calculate winding turns according to follow fomula.
AL=82.8 nH/N2 N= L = 44�1000 = 23.0 ()23() AL 82.8
AL=97.2 nH/N2 N= L = 44�1000 = 21.3 ()21() AL 97.2
AL=82.8 nH/N2Winding turns is maximum N= L = 44�1000 = 23.0 (turns)23(turns)
AL 82.8 AL=97.2 nH/N2 Winding turns is minimum
N= L = 44�1000 = 21.3 (turns)21(turns) AL 97.2
44H 21~23
From above calculation, to get the inductance of 44H, the number of turns can be between 21~23, it can be determined by the real AL value of the core.

MAGNETIC POWDER CORES
WWW.NCD.COM.CN
General Information
Brief introduction of magnetic powder cores and its materials
Magnetic Powder Cores consist of powders of soft magnetic materials and insulations. It can be used in a wide frequency range. It has lower power losses at high frequencies. As the air gaps are evenly distributed in the cores, it is very difficult to be fully magnetized. Therefore the apparent permeability is kept stable in a quite wide range of magnetizing field. The major materials being used currently are sendust alloy powder, silicon iron alloy powder, nickel iron alloy powder and other iron based alloy powders. Please see the details in the following:
NCD NCD FeSiAl powder core
NS EE EPFC 26-160
NS powder cores are made from alloy powders of iron, silicon and aluminum. Near-zero magnetostriction makes Sendust cores ideal for eliminating audible noise in filter inductors. Core losses of Sendust cores are significantly lower than those of powdered iron cores. Especially Sendust E shapes provide a higher energy storage capability than gapped Ferrite E cores. Gap losses and eddy current losses are minimized with Sendust E cores compared to gapped ferrite E shapes. Sendust cores are a smart choice for PFC circuits. Other major applications include switching regulator inductors, In-line noise filters, pulse transformers and flyback transformers. Finished Sendust cores are coated in a black epoxy. The permeability range of the cores is from 26-160.

General Information
NH alloy powder cores are made from a 50% nickel -50% iron alloy powder for the highest available biasing capacity of any powder core material. The 15,000 Gauss saturation level of High Flux cores has a higher energy storage capability and more effective permeability when compared to the performance of gapped ferrite or powdered iron cores of a similar size. The excellent DC bias characteristics and low core losses of High Flux cores offer a reduction in size and the number of winding turns as well as superior magnetic properties. NCD's High Flux cores give an excellent choice for applications such as PFC reactors, switching regulator inductors, in-line noise filters, pulse transformers and fly-back transformers. Finished High Flux cores are coated with a Khaki epoxy and come in a variety of shapes and sizes. The permeability range of the cores is from 26-125.
NCD NCD FeSi powder core
NKFeSi6.5FeSi6.5 19-90
NK powder cores are made from 6.5% silicon iron powder. Since the silicon content level of 6.5% silicon iron powder is higher than silicon steel sheet, the resistivity of silicon iron powder is higher than silicon steel sheet. The silicon iron powder also could be insulated in three dimensions instead of one dimension for silicon steel sheet, so the total eddy current loss in the particle and between particles are much lower than silicon steel sheet. The design of the K Flux cores includes a smaller size, higher current and higher energy storage capability. The excellent DC bias characteristics which only second to High Flux cores provides the best cost effective solution for high end applications including buck/boost inductors for high power supply systems, smoothing chokes for inverters and reactors for electric vehicles. K Flux cores are pressed without organic binders and have significantly lower core losses than powdered iron cores and Fe-Si strip cores. They also present excellent thermal properties with no thermal aging effects. Finished K Flux cores are coated with a dark brown epoxy. The permeability range of the cores is from19-90.

General Information
NCD NKS NCD NKS powder core
NKSNCDsendustFeSi sendustFeSi NKS NKS26-90
NKS powder cores are made of the new iron based alloy material developed by NCD independently. The core loss is similar to sendust powder core but much lower than FeSi powder core. The DC bias is a little bit lower than FeSi powder core but much better than sendust powder core. It offers the best cost performance ratio compared to any other core material. The overall magnetic characteristics of NKS powder core is similar to the amorphous powder core. Compared with amorphous powder core, NKS powder core has better thermal stability, neither aging nor noise problem. Finished NKS cores are coated with a sky blue epoxy. The permeability range of the cores is from26-90.
NCD NSW NCD NSW powder core
NSWNCD 26-6050kHz-100kHz NSW26-60
NSW powder cores are made of another new iron based alloy material developed by NCD independently. It offers the lowest core loss compared to any other core material. Both DC bias and core loss are better than MPP core in the permeability range of 26 through 60. The core could replace air gapped ferrite core in the frequency range of 50kHz through 100kHz so that the size of the component could be reduced and the copper wire could be saved as well. NSW powder core has better thermal stability, neither aging nor noise problem. Finished NKS cores are coated with a sky blue. The permeability range of the cores is from26-60.

Introduction to the manufacturing process of magnetic powder core
manufacturing flow chart
Insulation is the process to coat an insulating layer on the surface of each particle by chemical and physical method to increase the surface resistivity and adhesive property of the powder. Pressing is the process to put the insulated powder in a mold and compact the powder together by a huge pressure to get a core with specific shape. Sintering is the process to put the green cores into a kiln to strengthen the mechanical strength and release the stress, meanwhile to get the objective electromagnetic properties. Coating is the process to coat an insulated layer on the surface of the sintered cores to get the objective resistivity for copper wire winding. Inspection & packing is the process to have a final visual inspection, mark on the core, pack and release to warehouse.

AL = L/N2nH/N2100 kHz1mTAL Definition of inductance factor: AL = L/N2nH /N2. The inductance per single winding turn. The unit is nanohenry. It is measured at the flux density of less than 1 mili-Tesla and the frequency of 100 kHz. The AL values are determined by dimension & permeability of the cores instead of materials.
�8%�12%�2% The tolerance of the inductance of the cores is �8% or �12% which is related to the core size. The cores of one batch can be graded and packed into �2% rang of inductance individually according to customer's requirement so that the adjust frequency during the winding can be minimized. The winding efficiency can be increased and the related cost can be reduced as well.
