FRX090-90F

Ptc Resettable Fuses Overview

The FRX090-90F is a Radial Leaded PTC Resettable Fuse belonging to the FRX Series, manufactured by Fuzetec. This component functions as a Polymeric Positive Temperature Coefficient (PPTC) device designed for circuit protection. It operates by increasing resistance significantly upon detecting overcurrent or excessive temperature conditions, thereby limiting current flow to protect downstream components. The radial leaded package facilitates through-hole mounting on printed circuit boards. As a resettable fuse, it automatically returns to a low-resistance state once the fault condition is removed and the device cools down, offering a reusable alternative to traditional one-time fuses in electronic applications.

Ptc Resettable Fuses Feature Summary

• Polymeric positive temperature coefficient technology enables automatic reset functionality after fault clearance
• Radial leaded construction supports reliable through-hole PCB integration
• Provides dual protection against both overcurrent and excessive temperature events

Ptc Resettable Fuses Applications

• Consumer electronics circuit protection
• Portable device battery management systems
• General purpose overcurrent safeguarding in electronic assemblies

Ptc Resettable Fuses Procurement Notes

Verify the specific part number suffix and manufacturer documentation to confirm electrical ratings and package dimensions. Ensure compatibility with the target application's voltage and current requirements before integration. Cross-reference official datasheets from Fuzetec for precise thermal and electrical characteristics. Confirm that the radial lead configuration matches the design layout constraints.

Ptc Resettable Fuses Selection Notes

Select this component based on the required hold current and trip current specifications for the protected circuit. Consider the maximum operating voltage and the physical space available on the PCB for the radial leaded package. Evaluate the thermal environment to ensure the resettable fuse operates within its specified temperature range. Verify that the resettable nature aligns with the system's maintenance and reliability goals compared to non-resettable alternatives.
