EPCOS B65877 P26/25 Ferrite Cores EPCOS B65877 PQ26/25 ferrite cores are a preferred shape for power conversion. The main advantage compared to conventional round or rectangular e type is the optimised round leg and wider outer surface area lowers the thermal resistance by offering a larger area for heat dissipation. The shape also offers better shielding to the winding. To IEC 62317-13 EPCOS Ferrite Cores
