FeaturesofEPCores
EP Cores are round center-post cubical shapes, which enclose the coil completely. 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.
ApplicationofEPCores
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.
