Resettable PTCs Fuses

are Bel's unique polymer formulation PTC (positive temperature coefficient) devices offer superior circuit protection, with added resettable feature, in traditional radial lead and SMD Chip packages. Similar to our extensive line of traditional fuse products, our resettable fuses protect against harmful overcurrent and short circuit conditions. However, our PTC devices can also be used to protect against over temperature conditions not necessarily caused by excessive current.
