Circuit Protection

Circuit protection devices absorb the faults that would otherwise destroy a design: fuses and fuse holders, circuit breakers, TVS and ESD diodes, PTC resettable fuses, and varistors for surge clamping. Key manufacturers include Littelfuse, Bourns, Eaton, Bel Fuse, and TDK-EPC.

Manufacturers listed in Circuit Protection on Circuit Center include Bourns, Littelfuse, TDK, Littelfuse Inc., Bourns Inc., STMicroelectronics, SCHURTER Inc. and Panasonic Industry.
