78 POT CORE SET
Pot cores have found application in all types of inductive devices. The core configuration provides a high degree of self-shielding. It also facilitates gapping to enhance utility for a variety of magnetic designs.
Pot cores can be supplied with the center post gapped to a mechanical dimension or an AL value.
Weight indicated is per pair or set.
