Low-temperature-rise low-loss high-magnetic-conductivity and stacking characteristics manganese zinc ferrite

The invention discloses low-temperature-rise low-loss high-magnetic-conductivity and stacking characteristics manganese zinc ferrite. The low-temperature-rise low-loss high-magnetic-conductivity and stacking characteristics manganese zinc ferrite comprises a main body system and a composite system; the main body system consists of 36 to 43 percent by weight of Fe2O3, 45 to 49 percent by weight of MnO and 12 to 15 percent by weight of ZnO; the composite system accounts for 10 to 30 percent of the total mass of the main body system and comprises CoO, Co2O3, V2O5, Bi2O3, MoO3 and CuO. The low-temperature-rise low-loss high-magnetic-conductivity and stacking characteristics manganese zinc ferrite is low in loss, high in magnetic flux density and excellent in stacking property, the temperature rise is less than 15 DEG C under an application condition, and a magnetic core is excellent in stacking property and magnetic flux performance, stable in application temperature and relatively low in energy consumption and has excellent application performance on a filter, a switch power supply and a transformer. The low-temperature-rise low-loss high-magnetic-conductivity and stacking characteristics manganese zinc ferrite is suitable for the development trend of the electronic industry at present, the performance of devices utilizing the magnetic core is greatly improved, and the structural adjustment of the electronic industry and energy conservation and emission reduction in China can be effectively facilitated.
