Gap Toroidal Core (GTC)
Toroidal Choke Core (GTC)
Toroidal choke cores are manufactured with iron-based amorphous metal Ribbon. They are unique combination of ultra-high saturation induction, high energy storage capability and low core loss for high frequency magnetic components which are significantly smaller than conventional components.
