TRF600-160-2

Ptc Resettable Fuses Overview

The Littelfuse TRF600-160-2 is a PolySwitch resettable PPTC fuse designed for overcurrent protection in through-hole PCB applications. It features a radial leaded form factor with a 5 mm lead spacing and operates within a temperature range of -40°C to +85°C. Key electrical parameters include a hold current of 160 mA, a trip current of 320 mA, and a maximum voltage rating of 250 VDC. The device has a maximum resistance of 16 Ω and can withstand a maximum fault current of 3 A.

Ptc Resettable Fuses Feature Summary

• Provides reliable overcurrent protection by increasing resistance as it heats during fault conditions
• Offers automatic reset functionality after the fault condition is removed and the device cools down
• Designed for through-hole mounting on printed circuit boards with radial leads

Ptc Resettable Fuses Applications

• Protection of circuits, wiring harnesses, and PCB components
• Overcurrent protection for automotive actuators, screens, and small motors
• Telecom and networking equipment line protection

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix '2' against official Littelfuse documentation to confirm exact mechanical dimensions and agency approvals. Ensure the selected variant matches the required hold and trip currents for the target circuit design. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Ptc Resettable Fuses Selection Notes

Select this component based on the 160 mA hold current and 250 VDC rating requirements. Consider the 16 Ω maximum resistance impact on circuit performance. Verify that the radial leaded package fits the PCB layout constraints and that the operating temperature range meets environmental specifications.

Ptc Resettable Fuses Part Context

This part belongs to the Littelfuse TRF600 series of PolySwitch resettable fuses. The series offers various hold currents and voltage ratings in radial leaded packages. These devices are solid-state polymer positive temperature coefficient (PPTC) devices used for reusable overcurrent protection in electronic circuits.

Ptc Resettable Fuses Replacement Considerations

Compatible substitutes include TRF600-160-RA-B-0.5 and TRF600-160-RA-B-0.5-L from Littelfuse or All Sensors. Verify that alternative parts match the 160 mA hold current, 250 VDC rating, and radial leaded package configuration.
