SAT Nanocrystalline Epoxy Resin Magnetic Toroidal Core
The epoxy resin coated SAT tape-wound toroidal cores made of nanocrystalline or amorphous magnetic material, perform higher permeability, lower core loss and higher energy switching efficiency than ferrite and permalloy ones. It’s the best core material for common mode choke, smart energy meter, coil, toroidal transformer and electronic components. SAT magnetic toroidal cores make electronic components smaller, lighter and cleaner.
