PPTC Resettable Fuses

When an overcurrent event occurs, traditional fuses trip and need to be replaced. Our PPTC (polymeric positive temperature coefficient) resettable fuses offer a smarter, more efficient solution.

These "self-healing" devices automatically reset once the fault is cleared and the component cools down, allowing the circuit to resume normal operation without the need for manual replacement. This capability makes them ideal for portable electronic devices, industrial controls, telecom & broadcast instruments, USB port protection, and more.
