Large-Size Ferrite Cores

EPCOS / TDK Large-Size Ferrite Cores optimize the magnetic design for efficiency and thermal performance. Various cores provided include E, U, I, PM, and PQ in N27, N87, N88, N92, N95, and N97 ferrite cores. These large-size ferrite cores provide higher power ratings due to bigger air gaps, thicker wires for higher currents, and low loss ratings with high operating temperature ranges. EPCOS / TDK Large-Size Ferrite Cores are suitable for industrial applications, including motor drives, EV charging stations, and other renewable energy applications.
