RGE800

Ptc Resettable Fuses Overview

The Littelfuse RGE800 is a PolySwitch polymer PTC resettable fuse designed for through-hole radial mounting. It features a maximum operating voltage of 16V and a hold current (Ih) of 8A. The device trips at a minimum current of 13.6A and withstands a maximum fault current of 100A. Initial resistance is typically 5.6 mOhms, rising to a maximum of 17.5 mOhms after tripping. It operates within a temperature range of -40°C to 85°C and measures approximately 12.20mm in length with a lead spacing of 5.05mm.

Ptc Resettable Fuses Feature Summary

• Polymer-based self-resetting protection mechanism
• Radial lead disc package for through-hole installation
• High trip current capability relative to hold current

Ptc Resettable Fuses Applications

• Overcurrent protection in low-voltage electronic circuits
• Battery pack protection systems
• Peripheral interface circuit safeguarding

Ptc Resettable Fuses Procurement Notes

Verify the exact part number suffix when ordering, as distributors may list variants such as RGEF800 or RGE800HF. Confirm that the required 8A hold current and 16V rating align with your circuit design specifications before procurement. Ensure compatibility with through-hole assembly processes and verify RoHS compliance status if required by your manufacturing standards.

Ptc Resettable Fuses Selection Notes

Select this component for applications requiring high-current protection in compact radial packages. The 8A hold current suits power-hungry peripherals or battery lines where standard fuses would be impractical due to size or reset requirements. Consider the 16V maximum voltage limit strictly; do not exceed this rating in higher voltage systems. Evaluate thermal derating needs if ambient temperatures approach the upper 85°C limit.

Ptc Resettable Fuses Part Context

This device belongs to Littelfuse's PolySwitch RGEF series of resettable fuses. These components utilize conductive polymer technology to provide automatic circuit protection. The series is characterized by low initial resistance and fast response times compared to traditional fusible links, offering reusable protection solutions for consumer electronics and industrial control boards.
