Bel Fuse Circuit Protection PTC Fuses

Bel Fuse Circuit Protection PTC resettable fuses

Bel Fuse Circuit Protection resettable PTC fuses are Bel's unique polymer formulation PTC (Positive Temperature Coefficient) devices. They offer superior circuit protection, with an added resettable feature, and are available in traditional radial lead and SMD chip packages. Similar to Bel's extensive line of traditional fuse products, their resettable fuses protect against harmful overcurrent and short circuit conditions. However, Bel Fuse Circuit Protection's PTC devices can also be used to protect against over temperature conditions not necessarily caused by excessive current.
