16R500GPR

Ptc Resettable Fuses Overview

The Littelfuse 16R500GPR is a PolySwitch resettable PTC device from the 16R series, designed for overcurrent protection in general applications. It features radial leads and PCB mounting with a maximum operating voltage of 16 VDC. The component maintains a holding current of 5 A and trips at 8.5 A. It has a low resistance of 34 mOhms and supports a maximum fault current rating of 100 A. The device operates within a temperature range of -40°C to +85°C, with dimensions of 14.3 mm length, 10.4 mm width, and 3 mm height.

Ptc Resettable Fuses Feature Summary

• Provides reliable overcurrent protection by raising resistance as it heats to limit current flow during fault conditions.
• Offers resettable functionality allowing circuit restoration after cooling without replacing the component.
• Designed for compact PCB integration using radial leaded termination style.

Ptc Resettable Fuses Applications

• Protection for circuits, wiring harnesses, and PCB components
• Overcurrent protection in automotive actuators, screens, and small motors
• Power supply and telecom equipment circuit safeguarding

Ptc Resettable Fuses Procurement Notes

Verify that the ordering suffix GPR corresponds to the specific reel or cut tape packaging configuration required for your assembly process. Confirm that the 16VDC voltage rating and 5A holding current align with the target circuit's operational parameters. Ensure compatibility with the specified radial lead spacing and PCB mount style before finalizing procurement decisions.

Ptc Resettable Fuses Selection Notes

Select this component when a 16VDC maximum voltage rating and 5A continuous holding current are required for overcurrent protection. Consider the 34 mOhms initial resistance and 2.6 W power dissipation capabilities for thermal management. The radial lead form factor suits through-hole PCB mounting needs where space constraints allow for the 14.3 mm x 10.4 mm footprint.

Ptc Resettable Fuses Part Context

The 16R500GPR belongs to Littelfuse's POLY-FUSE 16R series of resettable PTC devices. This series provides various products for general applications with a maximum 16 volts rating and up to 100-ampere short circuit rating capability. It falls under the broader category of PolySwitch resettable fuses used for solid-state overcurrent protection.

Ptc Resettable Fuses Replacement Considerations

Cross-reference other parts within the 16R series radial leaded lineup for alternative holding currents or trip characteristics. Verify that any substitute maintains the same 16VDC maximum voltage rating and radial lead package dimensions to ensure mechanical and electrical compatibility.
