Abstract

The MnZn ferrite material includes principal components and auxiliary components, where the principal components include: 52.5 mol % to 53.8 mol % of Fe2O3, 8.8 mol % to 12 mol % of ZnO, and the balance of MnO; the auxiliary components include: 0.35 wt % to 0.5 wt % of Co2O3, 0.03 wt % to 0.08 wt % of CaSiO3, 0.01 wt % to 0.04 wt % of Nb2O5, and 0.05 wt % to 0.12 wt % of TiO2 and RE elemental components; the RE elemental components include one or more from the group consisting of 0 wt % to 0.04 wt % of Gd2O3, 0 wt % to 0.02 wt % of Ho2O3, and 0 wt % to 0.03 wt % of Ce2O3; the auxiliary components are all represented by a mass percentage relative to a total mass of the Fe2O3, the MnO, and the ZnO.
