Abstract:
An object of the present invention is to provide a ferrite material that is excellent in temperature characteristic and DC superimposition characteristic. The present invention relates to Ni—Zn—Cu-based ferrite particles comprising 70 to 95% by weight of an Ni—Zn—Cu ferrite having a specific composition, 1 to 20% by weight of nickel oxide, 0 to 20% by weight of zinc oxide and 1 to 10% by weight of copper oxide, and a ferrite sintered ceramics obtained by sintering the ferrite particles.
