Commonly used iron powder cores are composed of carbon-based ferromagnetic powder and resin carbon-based ferromagnetic powder. Lowest price among powder cores. The saturation magnetic induction value is about 1.4T; the magnetic permeability ranges from 22 to 100; the initial magnetic permeability μi has good stability with the change of frequency; the DC current superposition performance is good; but the loss is high at high frequencies. The initial permeability of the iron powder core varies with the DC magnetic field strength and frequency.
