FERRITE SINTERED COMPACT, FERRITE CORE, AND COIL COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide a ferrite sintered compact having high magnetic permeability while maintaining its Curie temperature, a ferrite core made of the ferrite sintered compact, and a coil component obtained by coiling the ferrite core with a metal wire.SOLUTION: The ferrite sintered compact has high magnetic permeability while maintaining its Curie temperature so as to contain ferrite crystals in which the mass of Fe in the central part is higher than the mass of Fe in the outer marginal part. Further, the excellent removal capacity of a nozzle is exhibited by using a coil component obtained by coiling a ferrite core made of the ferrite sintered compact with a metal wire.
