Ferrite Attributes

Initial permeability of soft ferrites is typically desired to be between 10 and 15,000. It is important that there are no intrinsic gaps within the core to ensure permeability is consistent throughout the magnetic path length of the ferrite. Depending on the frequency for the intended use, for power applications frequencies generally greater than 10 kHz will call for materials with an initial permeability of about 2,000 and below. With suppression applications, one is generally working with frequencies above 500 kHz and will call for a wide range of permeabilities.
