New line of amorphous magnetic C-cores

Archived; click post to view.
Excerpt: Amorphous cores offer several advantages over cores made of silicon steel, ferrite, and powdered iron. With a higher saturation induction, the cores are half the size and weight. The ultra-thin lamination thickness of one mil (25 um) results in significantly lower core losses. Amorphous cores can op …
