RLD30P160UF

Ptc Resettable Fuses Overview

The Littelfuse RLD30P160UF is a PolySwitch radial leaded PPTC resettable fuse from the RLD30 series, designed for overcurrent protection in low-voltage circuits. It features a hold current of 1.6 A and a trip current of 3.2 A at a maximum voltage rating of 30 VDC. The device exhibits a minimum resistance of 90 mOhms and a maximum resistance of 110 mOhms, with a power dissipation rating of 900 mW. It supports a fault current rating of 40 A and operates within a temperature range of -40°C to +85°C. The component utilizes a radial lead configuration with a 5.1 mm lead spacing.

Ptc Resettable Fuses Feature Summary

• Provides reliable overcurrent protection by increasing resistance as it heats to limit current flow
• Offers resettable functionality to restore circuit operation after cooling down post-fault
• Designed for PCB mounting with radial leads compatible with high-volume electronics assembly

Ptc Resettable Fuses Applications

• General electronics equipment
• Computer and peripheral devices
• Automotive electronics systems

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix 'UF' against official Littelfuse documentation to confirm exact packaging or material specifications, as standard datasheets may list generic series variants. Ensure the component meets RoHS compliance requirements for your target market. Confirm availability status directly with authorized distributors, as lifecycle changes may affect supply chain stability. Cross-reference the part number with the latest approved parts list to avoid ordering obsolete or discontinued revisions.

Ptc Resettable Fuses Selection Notes

Select this component when a 1.6 A hold current and 30 VDC rating align with the circuit's operational parameters. The radial lead form factor is suitable for through-hole PCB mounting where space allows for the specified dimensions. Consider the 900 mW power dissipation and thermal characteristics to ensure proper heat management during normal operation and tripped states. Verify that the 40 A fault current rating exceeds the potential short-circuit currents in the application.

Ptc Resettable Fuses Part Context

This part belongs to the Littelfuse RLD30 series of PolySwitch resettable fuses, which are engineered for low-voltage applications up to 30 VDC. The series provides a comprehensive solution for protecting circuits in consumer electronics, automotive, and industrial control systems. These devices serve as an alternative to traditional single-use fuses, offering cost-effective protection by resetting automatically after the fault condition is removed and the device cools.
