MATERIAL DESCRIPTION
-2 Material -33 Material

 The low permeability of this material will result in lower operating AC flux density than with other materials with no additional gap-loss.

 

 An inexpensive alternate to the -8 Material for applications where high frequency core loss is not critical. Good linearity with high bias.

 

-8 Material -38 Material

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

 

 A higher permeability alternate to -26 Material. A low cost material best used at line frequency.

 

-18 Material -40 Material

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

 

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

 

-26 Material -45 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.

 

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

 

-28 Material -52 Material

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

 

 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.
