60R050XPR

Ptc Resettable Fuses Overview

The Littelfuse 60R050XPR is a radial leaded polymer PTC resettable fuse from the POLY-FUSE 60R series. It features a maximum voltage of 60 VDC and a hold current (Ih) of 500 mA. The trip current (It) is specified at 1 A, with a maximum interrupt rating of 40 A. Initial resistance (Ri) is typically 500 mOhms minimum, rising to a maximum post-trip resistance (R1) of 1.17 Ohms. The device operates within a temperature range of -40°C to +85°C and has a trip time of 4 seconds. Dimensions are 7.90mm diameter by 3.10mm height.

Ptc Resettable Fuses Feature Summary

• Utilizes polymer technology for self-resetting overcurrent protection without manual replacement
• Provides rapid response to overcurrent conditions with a documented 4-second trip time
• Constructed with flame-retardant epoxy coating meeting UL 94V-0 standards
• Designed for through-hole mounting with radial leads for standard PCB integration

Ptc Resettable Fuses Applications

• Overcurrent protection for low-voltage DC circuits up to 60V
• Protection of portable electronic devices and battery-powered equipment

Ptc Resettable Fuses Procurement Notes

Verify component authenticity against Littelfuse official documentation. Confirm RoHS3 compliance status as per recent PCN updates regarding coating material changes. Ensure ordering suffixes match required packaging formats such as cut tape or tape and reel. Cross-reference datasheet revisions to guarantee parameter consistency during procurement.

Ptc Resettable Fuses Selection Notes

Select this model for applications requiring a 500 mA hold current and 60 VDC rating. Consider the 1.17 Ohm maximum post-trip resistance for voltage drop calculations. Evaluate ambient operating temperatures between -40°C and +85°C. Compare physical dimensions against available PCB space constraints before finalizing the design.

Ptc Resettable Fuses Part Context

This component belongs to the Littelfuse 60R series of radial leaded PPTC fuses. The series offers various hold currents ranging from 100 mA to higher values, all sharing a common 60 VDC maximum voltage rating. The 60R050XPR specifically targets mid-range current protection needs within compact electronic assemblies.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes within the same series include 60R050-PB and 60R050XU, which share identical electrical ratings but may differ in packaging or specific manufacturing lot characteristics. Verify lead spacing and dimensional compatibility when swapping packages.
