toroidal inductors and transformers - wikipedia

Toroidal inductors and transformers - Wikipedia

Toroidal inductors and transformers are inductors and transformers which use magnetic cores with a toroidal (ring or donut) shape. They are passive electronic components , consisting of a circular ring or donut shaped magnetic core of ferromagnetic material such as laminated iron , iron powder, or ferrite , around which wire is wound.
