This particular shape minimizes the effect of air gaps formed at mating surfaces in the magnetic path and provides a larger volume ratio to total space used. Shielding is excellent. Special advantages of ferrite EP Core assemblies: wide core selection like; high packaging density on PCBs; choice of linear or flat temperature characteristics; consistency and uniformity. Application of EP Cores High permeability EP-core can be used as EMI filter core, choke coil core, power inductor core, and for telecommunication like xDSL modem transformers. EP-core can meet low THD (Total Harmonic Distortion) over a wide temperature range and wide frequency range. Therefore EP cores are suitable for high performance transformer design for xDSL modem application. wideEPtemperature range and widetoroid frequency EP cores,EP kerne,ferrite core,EP-core,EMC Suppression Cores,gapped core range.
