    摘要: The invention discloses a soft-magnetic MnZn system power ferrite, and aims at providing a soft-magnetic MnZn system power ferrite with high saturation magnetic flux density and low loss. The soft-magnetic MnZn system power ferrite comprises a main component and an auxiliary component; the main component comprises Fe 2 O 3 , MnO, ZnO and NiO; calculated on the basis of the total weight of the main component, Fe 2 O 3 accounts for 53.0-55.0mol%, ZnO accounts for 3.0-7.0mol%, NiO accounts for 0-1.0mol%, and MnO accounts for the balance; and the auxiliary component comprises CoO, SiO 2 , CaCO 3 , Nb 2 O 5 and ZrO 2 . The soft-magnetic MnZn system power ferrite has the beneficial effects that the saturation magnetic flux density Bs at 100°C is larger than 460mT, and the magnetic core loss Pcv at 100°C is smaller than 320kW/m 3 ; the soft-magnetic MnZn system power ferrite has such favorable performance, so that a device can be further miniaturized in the actual application of a product; and because of rather low loss, the work efficiency of the device can also be further increased.
