RLD60P050XFF

Ptc Resettable Fuses Overview

The Littelfuse RLD60P050XFF is a PolyFuse resettable PTC fuse from the RLD60 series, designed for PCB mounting with radial leads. It features a hold current of 500 mA and a trip current of 1 A, operating at a maximum voltage of 60 VDC. The device has a maximum rated current of 40 A and an initial resistance of 2.3 ohms. It functions within a temperature range of -40°C to +85°C, with a lead spacing of 5.1 mm and a diameter of 7.9 mm.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection by increasing resistance in response to overcurrent conditions
• Offers manual reset capability after fault clearance without component replacement
• Designed for through-hole mounting on printed circuit boards

Ptc Resettable Fuses Applications

• Portable electronic devices requiring compact circuit protection
• Peripheral equipment interfaces such as USB ports
• Battery-powered consumer electronics

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix XFF against official Littelfuse documentation to confirm lead plating and packaging details. Confirm RoHS compliance status directly from the manufacturer datasheet before integration. Ensure the selected variant matches the required axial or radial lead configuration for the target PCB layout.

Ptc Resettable Fuses Selection Notes

Select this component when a low holding current near 500 mA is required for sensitive circuits. The 60 VDC rating suits low-voltage digital logic and communication lines. Consider the 2.3 ohm resistance impact on signal integrity and power loss during normal operation compared to lower-resistance alternatives.

Ptc Resettable Fuses Part Context

This part belongs to the RLD60 series of PolyFuse resettable fuses, which are engineered for high-reliability applications in portable electronics. The series provides a cost-effective alternative to traditional one-time fuses by allowing repeated use after thermal recovery, simplifying maintenance and reducing long-term system costs.

Ptc Resettable Fuses Replacement Considerations

Consult Littelfuse technical resources for verified cross-reference data. Substitution requires matching hold current, trip current, and voltage ratings precisely to maintain circuit safety and performance specifications.
