Sendust Cores – FeSiAl Powder Core for PFC Inductors & EMI Filters

Sendust Core , is manufactured from an alloy containing approximately 85%Fe, 9% Si, and 6% Al. It offers significantly lower core loss than conventional iron powder cores, a high saturation flux density of up to 10,500 Gauss, and near-zero magnetostriction, making it ideal for low-noise power magnetic applications.Unlike bonded powder materials, FeSiAl cores are manufactured without organic binders, eliminating thermal aging issues and enabling continuous operation at temperatures up to 200°C. Available in permeabilities from 26μ to 125μ and a wide variety of shapes, including toroidal, U-core, E-core, and block cores , the KS Series is an excellent choice for PFC inductors, pulse transformers, energy storage inductors, output filter inductors, and EMI noise filters.
