EE iron powder cores.

EE iron powder cores used in DPE chokes. The distributed air gap properties inherent in EE iron powder cores also make them extremely well-suited for a variety of energy storage inductor applications. The iron powder core is composed of an iron based, rapidly solidified metallic alloy. Unlike ferrite cores, the high permeability iron powder cores are capable of handling higher flux densities and higher power levels without saturating.
