Iron Silicon (Fe-Si) Cores

Fe-Si cores display high saturation magnetisation, near zero magnetostriction and higher resistivity. Having a distributed air gap means Fe-Si powder cores have lower losses than Fe-Si tape-wound cores. The combination of high saturation flux density and high DC bias makes Fe-Si powder cores an ideal choice for high powder densities, where a low number of winding turns, low core loss and smaller size are required in today’s power supply systems; especially in high energy storage applications (a 30% reduction in volume is possible compared to Iron Powder). The DC bias characteristics are excellent when compared to Super MSS and Iron Powder of similar permeabilities and size. Relative Cost - Low
