Sendust Core
Sendust Core, which is made from 6%Al,9%Si and 85%Fe,is mainly used to replace iron powder core because its core loss is80%less than powdered iron, so it can be applied with the frequency above 8kHz.Sendust core has a saturation flux density of1.05T and permeability from 14 to 125.The nearly zero magnetostriction alloy makes sendust ideal for eliminating audible frequency noise. Sendust core also has better DC bias characteristics than MPP and the best cost performance. It is mainly applied in AC inductor, output inductor ,in-line filter, power factor correction inductor etc. It can also be used as transformer core in some circumstances.
High Flux Cores
High Flux Core is made from 50%Ni and 50%Fe.It has a saturation flux density of 15000Gs and permeability from 14 to 25.In magnetic powder cores, High Flux Core has the highest flux density and best DC bias characteristics among all other materials such that core size could be smaller and less expensive than MPP. It is mainly applied in in-line filter, AC inductor, output inductor, power factor correction circuit etc.
MPP Cores
MPP Core is made from 81%Ni,2%Mo,17%Fe,It has a saturation flux density of 7500Gs and permeability from 26 to 125,MPP core also the lowest core loss in magnetic powder cores and excellent temperature stability among all other materials ,but its price is the most expensive .The nearly zero magnetostriction alloy makes MPP Core ideal for eliminating audible frequency noise, It is mainly applied in high Q filter, LC circuit for high temperature stability, output inductor, power compensation circuit etc.
Si-Fe Cores
Si-Fe Core is made form 94%Fe and 6% Si. It has a saturation flux density of 16000Gs and permeability from 14 to 90.A true high temperature material, with no thermal aging, Si-Fe Core offers lower core losses than powdered iron cores and superior DC Bias performance. Si-Fe Core also has excellent temperature stability and high energy storage capability. Si-Fe Core is mainly used in PFC circuit, power inductor etc.
HFF Cores
HFF Cores is made form 85%Fe and 15%Si-Ni .It has saturation flux density of 16000Gs and permeability is between 26-90.HFF Core loss is nearly half of Si-Fe Cores and very close to the High Flux Cores. Its DC-Bias is also better than Si-Fe Cores and same as the High Flux Cores. It can replace Si-Fe Cores to improve the efficiency of products in high current applications. Main application of HFF Cores is in PFC Chokes and Power Inductors. It is also widely used in solar, wind energy, hybid powered vehicles.
Low Cost Si-Fe Cores
Low Cost Si-Fe Cores (CW Core) is a new generation low cost powder core. It has a saturation flux density of 14000 Gauss and permeability from 26-60. CW Core has low core loss, and excellent DC-Bias characteristics. CW Core also has excellent temperature stability and high energy storage capability. CW Core is mainly used in high current application, just as UPS, Solar inverter, etc.
Super Sendust Cores
Super Sendust Cores (CS-HF) which has good DC bias characteristics close to Si-Fe cores with core losses similar to Sendust Cores. High permeability CS-HF cores (75-125μ) will be an economic solution for applications which require high permeability such as low power switching power supply, server power, automotive, solar power. CS-HF cores with low permeability (26-60μ) are applied to various large current applications which lower losses and excellent DC bias characteristics are critical. They are applied to various applications such as UPS, power Inverter, industrial power.
