Part Number: 6578200121
78 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.
