RGEF1000-1

Ptc Resettable Fuses Overview

The Littelfuse RGEF1000-1 is a radial-leaded PolySwitch resettable PTC device designed for overcurrent protection. It features a hold current of 10 A and a trip current of 18.5 A, with a maximum operating voltage of 16 VDC. The component exhibits a typical resistance of 10.2 mΩ and can withstand a maximum fault current rating of 100 A. It operates within a temperature range of -40°C to +85°C and utilizes a through-hole mounting style with a rectangular package.

Ptc Resettable Fuses Feature Summary

• Provides reliable overcurrent protection by raising resistance as it heats to limit current flow during fault conditions.
• Features a radial-leaded form factor suitable for through-hole PCB mounting in compact circuit designs.
• Offers automatic reset functionality after the fault condition clears and the device cools down.

Ptc Resettable Fuses Applications

• Protection of circuits, wiring harnesses, and PCB components from overcurrent events.
• Overcurrent protection for automotive actuators, screens, and small motors.
• Circuit protection in telecom and power supply applications.

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm exact electrical ratings and compliance status. Ensure the selected variant matches the required hold and trip currents for the target application. Confirm RoHS compliance and agency approvals such as UL or CECC if required for the end product certification process.

Ptc Resettable Fuses Selection Notes

Select this component based on the required hold current of 10 A and the system voltage not exceeding 16 VDC. Consider the thermal environment, as the maximum operating temperature is rated at 85°C. Evaluate the physical space constraints for the radial-leaded rectangular package and ensure the lead spacing accommodates the PCB layout design requirements.

Ptc Resettable Fuses Part Context

This part belongs to the RGEF series of PolySwitch resettable fuses from Littelfuse. The RGEF series is characterized by low hold currents up to 14 A and is distinct from the RHEF series, which offers flatter thermal derating and higher operating temperatures up to 125°C. Both series utilize radial-leaded devices for comprehensive circuit protection capabilities.
