EP Cores

Part Number: 6595130121

95 EP CORE SET

EP designs reduce the effect of residual air gap upon the effective permeability of the core, hence they minimize coil volume for a given inductance. EP cores also provide a high degree of isolation from adjacent components and are advantageously used in low power devices, matching and broadband transformers.

•EP cores can be supplied with the center post gapped to a mechanical dimension or an ALvalue.

AL value is measured at 1 kHz, B < 10 gauss

A low loss MnZn ferrite material for power applications up to 200 kHz with low temperature variation. New type of 95 material is a low loss power material which features less power loss variation over temperature (25-100°C) at moderate flux densities for operation below 200 kHz.

Available in 95 material:

Toroids

U Cores
