Gapped Cores and Toroids

Ceramic Magnetics is an industry leader in custom gapped cores. Our family of Micro-Gapped Toroids offers an efficient, low loss, high-energy solution for switching power supplies and linear devices with permeability ranging from 100 to 400.

Core sizes from 0.165 to 0.4" OD, 0.09” to 0.2” ID, and as small as 0.02” high are available. Gapped toroids can reduce size, reduce losses, and are less noisy than other core technologies. They are a cost effective alternative to gapped shapes in transformers or powdered metal cores in output chokes. We also offer the ability to fabricate custom formed cores with distributed gaps.
