Super MSS (Improved Sendust)
Available in Permeabilities of 26, 60, 75, 90 and 125. Notable attributes of Super-MSS are that it is a low loss material compared to Iron Powder; low cost compared to Hi-Flux and MPP and has a very low magnetostriction coefficient relative to Iron Powder. This means extremely low levels of mechanical noise, in operation, making it popular in EMI inductors where low frequency AC is being filtered. Core losses are higher than MPP but less than Hi-Flux and substantially lower than Iron Powder. Super MSS is low in permeability and thus is well suited for energy storage inductor applications.
Note: As temperature increases, Super MSS cores exhibit a decrease in inductance, compared to all other powder materials, which display an increase. This can be used to advantage in temperature compensation when used with another powder material in a composite structure.
Limited Permeabilities available compared to MPP material
Significantly lower core losses than Iron Powder for a relatively small price premium.
Energy storage filter inductors used in switch-mode power supplies
Check out our range of Cosmo Ferrites They provide a high quality, low cost alternative to Ferroxcube™, Epcos™, TDK™ etc.. Many cores are held ex-stock and factory lead-times are much lower than the industry average.
