FERRITE COMPOSITION, FERRITE SINTERED BODY, AND ELECTRONIC DEVICE

A ferrite composition includes a main component and a sub component. The main component includes an iron oxide in terms of Fe2O3, a copper oxide in terms of CuO, a zinc oxide in terms of ZnO, and a nickel oxide as its remainder. The sub component includes a cobalt oxide in terms of Co3O4, a tin oxid...

Beschreibung
Zusammenfassung:	A ferrite composition includes a main component and a sub component. The main component includes an iron oxide in terms of Fe2O3, a copper oxide in terms of CuO, a zinc oxide in terms of ZnO, and a nickel oxide as its remainder. The sub component includes a cobalt oxide in terms of Co3O4, a tin oxide in terms of SnO2, and a bismuth oxide in terms of Bi2O3. A is −3.5 or more and 1.0 or less, provided that A=(α−18)/β; is defined, in which α is an amount of the zinc oxide represented by mol % in terms of ZnO in the main component, and β is an amount of the cobalt oxide represented by parts by weight in terms of Co3O4 with respect to 100 parts by weight of the main component.
