soft magnetic material

-2/-14 Materials:

The low permeability of these materials will result in lower operating AC flux density than other materials with on additional gap-loss. The -14 material is similar to-2 material with higher permeability.

-8/Material:

This material has low core loss and good linearity under high bias conditions. A good high frequency material. The highest cost material

-18/Material

This material has low core loss similar to -8 materials with higher permeability and a lower cost. Good DC saturation characteristics

-19/Material

An inexpensive alternate to the -18 materials 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.

-28/-30 Materials

The good linearity, low cost, and relatively low permeability of this material make it popular in large sizes for high power UPS

-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.

-38/Material

With its high magnetic permeability, is a low budget alternate of -26 material, popular in large sizes.

-40 materials

The least expensive material. It has characteristics quite similar to the very popular -26 material popular in large sizes.

-45 materials

The highest permeability material. A high permeability alternate to -52 material with slightly higher core losses.

-52 materials

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.
