| 发明名称 | Ferrite composition and electronic component | ||
| 摘要 | A ferrite composition comprises a main component and a sub component. The main component is comprised of 40.0 to 49.8 mol % iron oxide in terms of Fe2O3, 5.0 to 14.0 mol % copper oxide in terms of CuO, 0 to 32.0 mol % zinc oxide in terms of ZnO, and a remaining part of nickel oxide. The sub component includes 0.5 to 4.0 wt % tin oxide in terms of SnO2, 0.10 to 1.00 wt % bismuth oxide in terms of Bi2O3, and 0.21 to 3.00 wt % cobalt oxide in terms of Co3O4, with respect to the main component. | ||
