The invention provides a high-strength soft magnetic ferrite core. Ferrite powder comprises a main component and an auxiliary component, the ferrite powder is prepared by mixing and grinding a main component and an auxiliary component, and the average particle size of the ferrite powder is 0.9 +/-0.1 [mu] m by a ventilation method; the main components comprise the following components in percentage by weight: 50.0 to 54 percent of Fe2O3, 37 to 41 percent of MnO and 4 to 8 percent of ZnO; relative to the total amount of the main components, the auxiliary components comprise the following components in percentage by weight: 0.1 to 0.30 percent of CaCO3, 0.1 to 0.4 percent of TiO2, 0.0005 to 0.05 percent of MoO3, 0.003 to 0.02 percent of Bi2O3 and 0.02 to 0.05 percent of V2O5. The soft magnetic ferrite material disclosed by the invention has the beneficial effects that the soft magnetic ferrite material adopts conventional raw materials, is relatively low in cost, and has relatively high magnetic permeability and relatively low magnetic core loss.
