Soft Magnetic Powder Core Introduction

Soft magnetic powder core is a soft magnetic material made by mixing ferromagnetic powder and insulating medium. Since the ferromagnetic particles are very small (0.5~5 microns used at high frequencies) and are separated by non-magnetic electrical insulating film materials, on the one hand, eddy currents can be isolated, and the material is suitable for higher frequencies; on the other hand, due to the particles The gap effect between the two leads to the material with low magnetic permeability and constant magnetic permeability; and because the particle size is small, the skin phenomenon basically does not occur, and the change of magnetic permeability with frequency is relatively stable.
