Powder Metal Cores--Sailcrest Magnetics Material Group

Powder Matal Cors

Sendust

Distributed air gap toroid cores made from silicon iron alloy powders. Material permeability's range from 26µi to 125µi with standard core sizes from 6.35mm to 58.0mm. Cores are coated with an epoxy coating which provides a tough outer surface with a minimum breakdown voltage of 500Vac. Sendust cores are colour coded in black.
