Description
technical field [0001] The invention relates to the technical field of ferrite materials, in particular to a high-performance ferrite core material. Background technique [0002] With the rapid development of electronic information technology, metal magnetic powder cores are widely used in the fields of line filters, output inductors and switching power supplies. Magnetic materials are mainly divided into iron powder cores, iron silicon magnetic powder cores, high flux magnetic powder cores, sendust magnetic powder cores, sendust silicon nickel magnetic powder cores, iron nickel molybdenum magnetic powder cores and amorphous nanocrystalline magnetic powder cores. A soft magnetic composite material obtained by mixing ferromagnetic powder particles with an insulating medium and then pressing them is called a metal magnetic powder core. After the ferromagnetic powder particles are insulated and coated, a layer of insulating dielectric film is formed on the surface, which can e...
