Abstract
Official abstract text for this publication.
A ferrite composition composed of a main component including 26 to 46 mol % of an iron oxide in terms of Fe 2 O 3 , 4 to 14 mol % of a copper oxide in terms of CuO, 0 to 26 mol % of a zinc oxide in terms of ZnO, and a residue of 40.0 mol % or more of a nickel oxide in terms of NiO. The ferrite composition, with respect to 100 parts by weight of the main component, is also composed of a subcomponent including 0.8 to 10.0 parts by weight of a silicon compound in terms of SiO 2 , 1.0 to 15.0 parts by weight of a cobalt compound in terms of Co 3 O 4 , and 0.7 to 30.0 parts by weight of a bismuth compound in terms of Bi 2 O 3 . A value of the cobalt compound content in terms of Co 3 O 4 divided by the silicon compound content in terms of SiO 2 is 0.4 to 5.5.

Opening claim text (preview).
1 . A ferrite composition comprising a main component and a subcomponent, in which the main component comprises 26 to 46 mol % of an iron oxide in terms of Fe 2 O 3 , 4 to 14 mol % of a copper oxide in terms of CuO, 0 to 26 mol % of a zinc oxide in terms of ZnO, and a residue of 40.0 mol % or more of a nickel oxide in terms of NiO, the subcomponent comprises 0.8 to 10.0 parts by weight of a silicon compound in terms of SiO 2 , 1.0 to 15.0 parts by weight of a cobalt compound in terms of Co 3 O 4 , and 0.7 to 30.0 parts by weight of a bismuth compound in terms of Bi 2 O 3 , with respect to 100 parts by weight of the main component, and a ratio of a content of the cobalt compound in terms of Co 3 O 4 divided by a content of the silicon compound in terms of SiO 2 is 0.4 to 5.5. 2 . An electronic component comprising a ferrite sintered body composed of the ferrite composition as set forth in claim 1 .
