RGEF300-1

Ptc Resettable Fuses Overview

The Littelfuse RGEF300-1 is a radial leaded PolySwitch resettable PPTC device designed for overcurrent protection. It belongs to the RGEF series, featuring a hold current of 3 A and a trip current of 5.1 A. The component supports a maximum voltage rating of 16 VDC and offers a maximum fault current rating of 100 A. Its typical resistance is 97.5 mΩ, with an operating temperature range from -40°C to +85°C. The device utilizes a bulk packaging format and measures 3 mm in height.

Ptc Resettable Fuses Feature Summary

• Provides reliable overcurrent protection by raising resistance as it heats to limit current flow during fault conditions.
• Features automatic recovery functionality, eliminating the need for manual replacement after tripping events.

Ptc Resettable Fuses Applications

• Protection for automotive actuators, screens, and small motors
• Overcurrent safeguarding for circuit wiring harnesses
• PCB component protection against short circuits

Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix '-1' aligns with the manufacturer's official ordering nomenclature for the RGEF series. Confirm that the required electrical parameters, including the 3 A hold current and 16 VDC rating, match the application requirements. Ensure the radial leaded package style and bulk packaging format are compatible with the intended assembly process.

Ptc Resettable Fuses Selection Notes

Select this component when a resettable fuse is required for low-voltage DC applications up to 16 V. The 3 A hold current makes it suitable for protecting circuits with steady-state currents near this threshold. Consider the 100 A maximum fault current rating to ensure the device can withstand potential short-circuit events without damage.

Ptc Resettable Fuses Part Context

The RGEF300-1 is part of the Littelfuse PolySwitch resettable PPTC family. These devices serve as solid-state fuses, offering a reusable alternative to traditional one-time fuses. The RGEF series specifically targets automotive and industrial applications requiring robust protection for sensitive electronics and power distribution lines.

Ptc Resettable Fuses Replacement Considerations

The RGEF300 (without the -1 suffix) is a confirmed substitute within the same series, sharing identical electrical characteristics such as 3 A hold current and 16 VDC rating. Verify if the suffix indicates a specific packaging or variant difference before substitution.
