EP7, EP10, EP13, EP17, EP20 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 • Weigh indicates is per pair or set.
