FERRITE COMPOSITION, FERRITE SINTERED BODY, ELECTRONIC COMPONENT AND CHIP COIL
PROBLEM TO BE SOLVED: To provide a ferrite composition constituting a ferrite sintered body which is suitably used in a chip coil.SOLUTION: A ferrite composition has main components and accessory components. The main components include 43.0-51.0 mol% of an iron oxide in terms of FeO, 5.0-15.0 mol% of a copper oxide in terms of CuO, 1.0-24.9 mol% of a zinc oxide in terms of ZnO, and the balance nickel oxide. The ferrite composition contains, as the accessory components, 0.2-3.0 pts.wt. of a silicon compound in terms of SiO, 3.0-8.0 pts.wt. of a cobalt compound in terms of CoO(excluding 3.0 pts.wt.), and 0.2-8.0 pts.wt. of a bismuth compound in terms of BiO, with respect to 100 pts.wt. of the main components.SELECTED DRAWING: Figure 1
【課題】チップコイルに好適に用いられるフェライト焼結体を構成するフェライト組成物を得る。【解決手段】主成分と副成分とを有するフェライト組成物である。主成分が、酸化鉄をＦｅ２Ｏ３換算で４３．０〜５１．０モル％、酸化銅をＣｕＯ換算で５．０〜１５．０モル％、酸化亜鉛をＺｎＯ換算で１．０〜２４．９モル％、残部が酸化ニッケルで構成されている。主成分１００重量部に対して、副成分として、ケイ素化合物をＳｉＯ２換算で０．２〜３．０重量部、コバルト化合物をＣｏ３Ｏ４換算で３．０〜８．０重量部（３．０重量部を除く）、ビスマス化合物をＢｉ２Ｏ３換算で０．２〜８．０重量部、含有する。【選択図】図１
