Ptc Resettable Fuses datasheet and documents for RLD30P250UF

RLD30P250UF

Ptc Resettable Fuses Overview

The Littelfuse RLD30P250UF is a PolySwitch resettable PTC fuse designed for PCB mounting. It features a radial leaded form factor with a hold current of 2.5 A and a trip current of 5 A. The device supports a maximum voltage rating of 30 VDC and has a minimum resistance of 20 mOhms. It withstands a maximum fault current of 40 A and dissipates up to 1.2 W. The component operates within a temperature range of -40°C to +85°C, with a lead spacing of 10.2 mm.

Ptc Resettable Fuses Feature Summary

Provides reliable overcurrent protection for circuits, wiring harnesses, and PCB components through automatic resistance increase during fault conditions.
Offers a compact radial-leaded design suitable for direct installation on printed circuit boards.

Ptc Resettable Fuses Applications

Protection of automotive actuators, screens, and small motors
Overcurrent safeguarding for telephony and networking equipment
Circuit protection in power supply applications

Ptc Resettable Fuses Procurement Notes

Verify the exact suffix configuration against the manufacturer datasheet to ensure correct package and termination specifications. Confirm RoHS compliance status as indicated in official documentation. Check availability status, as this specific part number may be subject to discontinuation or limited distribution channels. Ensure the selected variant matches the required hold and trip current parameters for the target application circuit.

Ptc Resettable Fuses Selection Notes

Select this component when a 30 VDC rated resettable fuse with a 2.5 A hold current is required. The radial leaded format is appropriate for through-hole PCB assembly where space allows for 10.2 mm lead spacing. Consider the 20 mOhms minimum resistance for low-impact insertion into sensitive power lines. Evaluate the 40 A maximum fault current capability against potential short-circuit scenarios in the design.

Ptc Resettable Fuses Part Context

This device belongs to the RLD30 series of PolySwitch resettable fuses from Littelfuse. The series provides solid-state protection solutions that replace traditional fusible links. These components are engineered to automatically restore function after cooling down, offering reusable protection for electronic systems without requiring manual replacement.
