Kool Mµ (commonly referred to as Sendust) is a material offering low loss and relatively high saturation level (1.0T) that makes it excellent for use in any kind of storage inductor for example in switched-mode power supplies, power factor correction circuits (PFC), and flyback transformers.
The near-zero magnetostriction makes Kool Mµ ideal for eliminating audible frequency noise in in-line noise filters and inductors.
