| 发明名称 | Composite ferrite composition and electronic device | ||
| 摘要 | A composite ferrite composition comprises a magnetic material and a non-magnetic material. A mixing ratio of said magnetic material and said non-magnetic material is 20 wt %:80 wt % to 80 wt %:20 wt %. Ni—Cu—Zn based ferrite is used as the magnetic material. Oxides of Zn, Cu, and Si are at least included in a main component of said non-magnetic material. Borosilicate glass is included in a subcomponent of said non-magnetic material. | ||
