High Flux Core
Sendust Core, which is made from 6%AI, 9%Si and 85%Fe, is mainly used to replace iron powder core because its core loss is 80% less than powdered iron, so it can be applied with the frequency above 8kHz. Sendust Core has a saturation flux density of 1.05T and permeability from 26 to 125. The near zero magnetostriction alloy makes sendust ideal for eliminating audible frequency noise.

Sendust Cores
Sendust Core, which is made from 6%AI, 9%Si and 85%Fe, is mainly used to replace iron powder core because its core loss is 80% less than powdered iron, so it can be applied with the frequency above 8kHz. Sendust Core has a saturation flux density of 1.05T and permeability from 26 to 125. The near 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 to replace ferrite as the core of transformer.
Si-Fe Cores
Si-Fe core is made from 94% Fe and 6% Si. It has a saturation flux density of 16000Gs and permeability from 26 to 90. A true high temperature material, with no thermal aging, Si-Fe core offers lower core losses than powder iron cores and superior DC Bias performance. Si-Fe core also has excellent temperature stability and high energy storage capacity. Si-Fe core is mainly used in PFC circuit, power inductor etc.
High flux Cores
HF cores are is made from 50% Fe and 50% Ni. It has a saturation flux density of 15000Gs and permeability from 26 to 125. HF cores offer a higher energy storage capability and more effective permeability when compared to the 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. HF cores are excellent choices for applications such as PFC transformers, switching regulator inductors, in-line noise filters, pulse transformers and flyback transformers.

Temperature Effects |
||||||||
|
Common working temperature for iron powder core is between -65℃~+125℃. When the working environment temperature rises above 150℃, the organic adhesive (usually epoxy resin) will begin to decompose, resulting in the degradation of the device's performance and shortening of the device's life. The severity of the degrading depends on the time, temperature, size of the magnetic powder core, working frequency and the flux density. |

The cores are manufactured to the AL values listed; the permeability for each material is for reference only. In all cases, the AL values are based on perk AC flux density of 10 gauss(1mT) at a frequency of 10kHz. The toroidal cores are tested with an evenly-spaced full single-layer winding in order to minimize leakage effects. Iron powder cores tested with a small number of turns which are not evenly distributed will produce higher inductance readings than expected. The E Cores are tested with 100 turns. The Magnetic Characteristic curves shown have a typical tolerance of ±10%. The curves on Core Loss characteristics have a typical tolerance of ±15%.
Iron Powder Cores Product Characteristics
Material Description
-18 Material: This material has low core loss similar to the -8 Material with higher permeability and lower cost. Good DC saturation characteristics.
-19 Material: An inexpensive alternate to the -18 Material with the same permeability and somewhat higher core losses.
-26 Material: The most popular material. It is a cost-effective general purpose material that is useful in a wide variety of power conversion and line filter applications.
-30 Materials: The good linearity, low cost, and relatively low permeability of this material make it popular in large sizes for high power UPS chokes.
-33/-34/-35 Materials: An inexpensive alternate to the -8 Material for applications where high frequency core loss is not critical. Good linearity with high bias.
-40 Material: The least expensive material. It has characteristics quite similar to the very popular -26 Material. Popular in large sizes.
-52 Material: This material has lower core loss at high frequency and the same permeability as the -26 Material. It is very popular for high frequency choke designs.
