high-throughput magnetic powder core appeared in the middle of the last century, its standard huai composition: ni50%, fe50%; high-throughput magnetic powder core general coating color is yellowish green. due to the high saturation magnetic induction strength, the dc deflection characteristic is good, and the minimum dc drift of the inductance value is guaranteed in the larger dc offset field. the energy storage inductance used for switching power supply has greater energy storage efficiency than the same volume of iron powder core and ferrite, and can reduce the volume when used in large current inductors, which is used for filter inductors that do not produce saturation through large ac voltages, and can also be used for power factor correction circuits and unidirectional drive applications such as flyback transformers, pulse transformers, etc. effective magnetic conductivity range μe26~μe125, used in 1khz test conditions, the highest effective magnetic conductivity up to μe160.
