  • MAGNETIC MATERIAL COMPOSITION FOR CERAMIC ELECTRONIC COMPONENT, METHOD OF MANUFACTURING THE SAME, AND CERAMIC ELECTRONIC COMPONENT USING THE SAME
    Publication number: 20120132847
    Abstract: A magnetic material composition for ceramic electronic components that is excellent in sintering properties and magnetic properties (in particular, a Q-factor) and a manufacturing method thereof, and a ceramic electronic component using the magnetic material composition are provided. The magnetic material composition includes Ni—Zn—Cu ferrite powder formed of 47.0 to 49.5 parts by mole of a mixture of iron oxide (Fe2O3), cobalt oxide (CoO), and titanium oxide (TiO2), 16.0 to 24.0 parts by mole of nickel oxide (NiO), 18.0 to 25.0 parts by mole of zinc oxide (ZnO), and 7.0 to 13.0 parts by mole of copper oxide (CuO). A ceramic electronic component manufactured using the magnetic material composition has an excellent Q-factor.
