FRX300-90F

Ptc Resettable Fuses Overview

The FRX300-90F is a radial leaded PTC resettable fuse from the FRX90V series, manufactured by Fuzetec. It functions as a self-resetting overcurrent protection device designed for circuit safeguarding. The component utilizes positive temperature coefficient technology to limit current flow during fault conditions, automatically returning to a low-resistance state once the fault is cleared and the device cools down.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit recovery after overcurrent events without manual replacement
• Offers reliable thermal protection against excessive current flow in electronic circuits

Ptc Resettable Fuses Applications

• Overcurrent protection in consumer electronics assemblies
