U & I Cores EPCOS U cores are of rectangular cross section and I Cores are made of SIFERRIT Materials N27 and N87. Owing to their high saturation flux density, high curie temperature and low dissapation losses they are suitable for power, pulse and high-voltage transformers.U and I cores are supplied separately.

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

EPCOS B65877 PQ26/20 Ferrite Cores EPCOS B65877 PQ26/20 Ferrite cores have optimised round leg and wider outer surface to conventional cores. The round leg on these ferrite cores reduces winding length and the wider surface area lowers the thermal resistance by offering a larger area for heat dissipation. The shape also produces better shielding to the winding. To IEC 62317-13 EPCOS Ferrite Cores
