RGEF1000-2

Ptc Resettable Fuses Overview

The RGEF1000-2 is a polymeric PTC resettable fuse from the RGEF series, designed for through-hole radial mounting. It features a maximum voltage rating of 16 VDC and a hold current (Ih) of 10 A. The trip current (It) is specified at 17 A, with a maximum interrupting current of 100 A. Initial resistance (Ri) is typically 10.2 mOhms, while post-trip resistance (R1) reaches a maximum of 0.0102 Ohms. The device operates within a temperature range of -40°C to +85°C, with a maximum trip time of 6 seconds.

Ptc Resettable Fuses Feature Summary

• Polymer-based self-resetting circuit protection mechanism
• Radial leaded construction for standard PCB insertion
• High current interruption capability up to 100 A

Ptc Resettable Fuses Applications

• Overcurrent protection in consumer electronics assemblies
• Circuit safeguarding in automotive low-voltage systems
• Protection for portable device power inputs

Ptc Resettable Fuses Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number Littelfuse Inc. RGEF1000-2 against official datasheets. Confirm that the physical package matches the radial disc specification and that electrical parameters align with the 16V 10A ratings. Ensure compliance with RoHS3 standards as documented in the product specifications before integration into production lines.

Ptc Resettable Fuses Selection Notes

Select this component when a 10 A hold current and 16 VDC maximum voltage are required for radial PCB applications. The RGEF series offers a balance of low initial resistance and high trip speed compared to standard PolySwitch devices. Consider the 85°C operating limit and 6-second trip time characteristics to ensure adequate thermal management and response timing for the specific circuit design requirements.

Ptc Resettable Fuses Part Context

The RGEF1000-2 belongs to Littelfuse’s RGEF series of radial leaded PTC resettable fuses. This series is engineered for applications requiring robust overcurrent protection with space-constrained mounting options. The radial form factor facilitates automated assembly processes on printed circuit boards, distinguishing it from surface-mount alternatives within the broader PolySwitch portfolio.

Ptc Resettable Fuses Replacement Considerations

The RHEF1000-2 is a documented substitute within the same manufacturer lineup, offering similar 16V 10A specifications but potentially differing in packaging or minor electrical tolerances. Verify mechanical dimensions and thermal characteristics before substitution to ensure compatibility with existing board layouts and performance expectations.
