COMPOSITE FERRITE COMPOSITION AND ELECTRONIC COMPONENT |
| 摘要 |
Provided is a composite ferrite composition including a magnetic substance material and a nonmagnetic substance material. The magnetic substance material is Ni—Cu—Zn based ferrite. The nonmagnetic substance material comprises a low dielectric constant nonmagnetic substance material, which is shown by a general formula: a(bZnO.cCuO).SiO2 and satisfies a=1.5 to 2.4, b=0.85 to 0.98, c=0.02 to 0.15, and b+c=1.00 in said general formula, and a bismuth oxide. A mixing ratio of the magnetic substance material and the low dielectric constant nonmagnetic substance material is 80 wt %:20 wt % to 10 wt %:90 wt %. |
