RGEF600K-AP

Ptc Resettable Fuses Overview

The Littelfuse RGEF600K-AP is a PolySwitch radial-leaded PPTC resettable fuse designed for overcurrent protection. It features a hold current of 6 A and a trip current of 12 A, with a maximum voltage rating of 30 VDC. The device has a minimum resistance of 40 mOhms and a maximum fault current rating of 100 A. It operates within a temperature range of -40°C to +85°C and dissipates up to 3.5 W. The component utilizes a radial lead configuration with a 10.9 mm lead spacing.

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 the circuit to be restored after cooling without replacing the component.
• Designed for PCB mounting with radial leads to support high-volume electronics assembly processes.

Ptc Resettable Fuses Applications

• Protection for circuits, wiring harnesses, and PCB components in general electronics.
• Overcurrent safeguarding in battery-powered devices and rechargeable battery packs.
• Circuit protection in automotive applications for actuators, screens, and small motors.

Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix 'AP' corresponds to the required tape-and-reel or cut-tape packaging format, as this distinguishes it from bulk-pack variants like RUEF600K. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected part number matches the exact hold and trip current requirements for the target application circuit design.

Ptc Resettable Fuses Selection Notes

Select this component when a 6 A hold current and 30 VDC maximum voltage rating are required for radial-leaded PPTC applications. Consider the 100 A maximum fault current capability for short-circuit scenarios. Evaluate the 40 mOhms initial resistance for power loss considerations. Choose this variant over surface-mount options if through-hole mounting and specific lead spacing are necessary for the PCB layout.

Ptc Resettable Fuses Part Context

This part belongs to the Littelfuse PolySwitch radial-leaded series, which provides comprehensive PPTC solutions. It shares core electrical characteristics with the RUEF600K but differs in packaging configuration. The RUEF series is widely used in automotive and telecom sectors for protecting sensitive components from overcurrent events while maintaining low profile and compact form factors.

Ptc Resettable Fuses Replacement Considerations

The RUEF600K serves as a functional substitute with identical electrical ratings but typically comes in bulk packaging rather than reel/cut tape. Verify that the lead spacing and physical dimensions remain compatible with the existing PCB footprint when substituting between these packaging variants.
