60R050XU

Ptc Resettable Fuses Overview

The Littelfuse 60R050XU is a PolySwitch resettable PTC device designed for overcurrent protection in circuits operating at voltages up to 60 VDC. It features a hold current of 500 mA and a trip current of 1 A, providing reliable circuit interruption when fault conditions occur. The component has a maximum fault current rating of 40 A and a typical resistance of 1.17 Ohms. It operates within a temperature range of -40°C to +85°C and utilizes radial leads with a 5.1 mm spacing for PCB mounting.

Ptc Resettable Fuses Feature Summary

• Provides self-resetting overcurrent protection by increasing resistance upon heating during fault events
• Constructed with bent epoxy polymer material that meets UL 94V-0 flammability standards
• Features rapid tripping response times to limit damage during short circuits or overloads

Ptc Resettable Fuses Applications

• Protection of automotive actuators, screens, and small motors
• Overcurrent safeguarding for telecom equipment and wiring harnesses
• Circuit protection for power supply components and PCB assemblies

Ptc Resettable Fuses Procurement Notes

Verify the specific ordering suffix XU against the manufacturer's official datasheet to confirm lead frame plating and packaging specifications. Ensure the selected variant matches the required axial or radial lead configuration and voltage rating for the target application. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Ptc Resettable Fuses Selection Notes

Select this component based on the required hold current of 500 mA and maximum system voltage of 60 VDC. Consider the physical dimensions, including the 7.9 mm diameter and 3.1 mm length, for PCB layout constraints. Evaluate the thermal environment to ensure operation remains within the specified -40°C to +85°C range while accounting for ambient temperature derating factors.

Ptc Resettable Fuses Part Context

This part belongs to the 60R series of PolySwitch resettable fuses from Littelfuse. The series is engineered for applications requiring space-efficient overcurrent protection without permanent replacement after tripping. These devices serve as alternatives to traditional one-time fuses in automotive, industrial, and consumer electronics sectors.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other 60V PolySwitch radial leaded devices with matching 500 mA hold current ratings from the same manufacturer family. Verify equivalent electrical parameters such as trip current, maximum voltage, and package dimensions before integration.
