Fe-Si powder is an iron-silicon power consists of 6.5% silicon (Si). It's charactorized itself with very high saturation density (up to 16,000 Gauss), superior DC bias performance, high energy storage capacity as well as good temperature stability. It also delivers lower loss than iron powder. Mirrack's Fe-Si (MKF)'s permeabilities range from 26u to 90u. It's alternatively named as XFlux by Magnetics, or Mega Flux by Chung Sung (CSC), or Fluxsan by Arnold.

It's widely used in the renewable energies such as solar / PV, wind energy and hybrid powered vehicles as well as telecommunications' power supplies, server power supplies, UPS, etc., serving as power factor correction choke (PFC choke), switching regulator inductor, high current power choke, power inductor for energy storage, output inductor for general industrial power supplies, in-line noise filter / EMI filter.

● Stable quality and good conformity
