Detailed Product Description
Application:
Can replace silicon steel, permalloy and ferrite, as various forms of high-frequency (20kHz
100kHz) switching power supply in the medium and small power transformer, control transformer,
filter inductors, energy storage inductors, reactors, magnetic amplifiers, saturable reactor core,
EMC filter inductor common mode and differential mode inductor core, ISDN miniature isolation
transformer core; also widely used in all types of different precision of the transformer core.
Performance characteristics:
High saturation magnetic induction, high permeability, low coercivity, low loss and good stability,
wear resistance, corrosion resistance, also has a lower price, in all of the metal soft magnetic
materials with the best performance prices.
