SINTERED MnZn FERRITE BODY
A sintered MnZn ferrite body containing main components comprising 53.30-53.80% by mol of Fe calculated as Fe2O3, 6.90-9.50% by mol Zn calculated as ZnO, and the balance of Mn calculated as MnO, and sub-components comprising 0.003-0.020 parts by mass of Si calculated as SiO2, more than 0 parts and 0.35 parts or less by mass of Ca calculated as CaCO3, 0.30-0.50 parts by mass of Co calculated as Co3O4, 0.03-0.10 parts by mass of Zr calculated as ZrO2, and 0-0.05 parts by mass of Ta calculated as Ta2O5, pre 100 parts by mass in total of the main components (calculated as the oxides), and having an average crystal grain size of 3 μm or more and less than 8 μm and a density of 4.65 g/cm3 or more.
