Description:
EPCOS RM5 Ferrite cores are increasingly required for power applications. These cores are designed for two major applications low loss, highly stable filter inductors and other resonance determin Ing inductors. The other application is low distortion broadband transmission. These ferrite cores have no centre holes. IEC62317-4.

Description:
EPCOS B65879 PQ32/20 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 ...
