PTC Resettable Fuses
PTC Resettable Fuses are circuit protection components used to protect electronic systems from overcurrent, short-circuit and fault conditions. Unlike one-time fuses, PTC resettable fuses increase resistance during a fault and can return to a low-resistance state after the fault is removed and the device cools down.
This category includes polymer PTC resettable fuses, PPTC fuses, radial leaded PTC fuses, surface-mount PTC fuses and related overcurrent protection components. These devices are commonly selected based on hold current, trip current, rated voltage, resistance, response time, package type, operating temperature and application requirements.
TomatoElec supplies original PTC Resettable Fuses from recognized manufacturers such as Littelfuse, Bourns, Eaton, Bel Fuse, TE Connectivity, Murata, TDK, Panasonic and other major brands. As an in-stock electronic components supplier and independent distributor, TomatoElec provides inventory support, original component sourcing and BOM sourcing services for global customers.
