PTC Resettable Fuses
PTC Resettable Fuses are designed to stop current flow when it exceeds a certain limit (overcurrent protection). The Fuses work by increasing its resistance as its temperature rises due to the current increase. The trip current ranges from 14 mA to 50 A with the Time to trip ranging from 8 ms to 90 s. PTC = Positive Temperature Coefficient.
Sourcing Hamlin / Littelfuse PTC Resettable Fuses: in-stock lines for quick ship, BOM matching for multi-line builds, and original-channel screening — not keyword stuffing.
