POWER INDUCTORS SENDUST MATERIAL ( Al & Si & Fe ) Core Core Core Loss Loss Loss Although higher in core loss than MPP material, Sendust has approxi@300kHz mately 50% more energy storage capacity. Sendust has approximately 2/3 @50kHz @100kHz 5657 16000 83138 the flux density of High Flux material, but has a much lower core loss. 3 Sendust is an ideal tradeoff between storage capacity, core loss and cost.
