6 SOFT IRON POWDER CORE SERIES INTRODUCTION. 5 Iron powder core is a kind of soft magnetic material which is composed of iron powder and insulating material. After insulating treatment, the iron powder is pressed into required shape and size and goes through heating, and coating sometimes. The evenly distributed gap inside the iron powder core is the main feature. ADVANTAGES OF IRON POWDER CORE: 1. High Bs reaches up to10000 Gauss. 2. Permeability range from 6 to Wide working frequency from thousands Hz to hundreds Mega Hz. 4. Excellent DC bias performance 5. In various shapes of toroidal, E shape, U shape, rod shape, SMD and etc. 6. Working temperature in range -55 ~ +125 C Based on above features, iron powder core are widely used in power switching inductor, online noise filter, PFC inductor, choke,emi/rfi application and etc. The toroidal cores are coated with Epoxy coating. The coating has a dielectric strength of 600 voltages
