Title:
NI-CONTAINING LOW LOSS FERRITE FOR POWER SOURCE
Document Type and Number:
Japanese Patent JPH07257968
Kind Code:
A
Abstract:
PURPOSE: To obtain a ferrite material securing a small loss (core loss) and being usable as a material of the transformer of a switching power source, etc., with an Ni-contg. ferrite having high resistivity.
CONSTITUTION: This Ni-contg. low loss ferrite is a sintered compact based on a compsn. consisting of 40-52.5mol% Fe2O3, 5-47.5mol% NiO and ≤35mol% ZnO and free from the segregation of P in the crystal structure of the sintered compact.
