This standard specifies the series of soft ferrite materials used in inductive components (inductors and transformers) and their basic performance parameters. This standard applies to soft ferrite materials used in the electronics industry. This standard can be used as a guide for designers of inductance components to select soft ferrite materials. The values given in this standard are typical values of material parameters (performance). Direct conversion from material technical parameters to magnetic core technical parameters is quite difficult, and some are even impossible.
