Applications:
The ferrosilicon magnetic core has distributed air gap, especially
suitable for energy storage filter inductance in switching power
supply because of its high BS value and low loss. It has a higher
energy capacity compared with the iron core and ferrite with the
same volume, permeab.
Therefore, it is widely used in rotary transformer, pulse
transformer and power factor correction circuit because of its
stable performance in high temperature. It can be smaller than the
iron core, and now it is used to replace the iron core for the
transformer. It can also be used for noise filter inductance
without noise and magnetostriction
