MF-RX160/72-0

Overview

The Bourns MF-RX160/72-0 is a radial leaded, resettable PPTC fuse from the Multifuse MF-RX/72 series. It features a maximum voltage rating of 72 VDC and a hold current of 1.6 A. The trip current is specified at 3.2 A with a maximum resistance of 90 mΩ. It supports a maximum fault current of 40 A and operates within a temperature range of -40°C to +85°C.

Feature Summary

Provides automatic circuit protection through polymer positive temperature coefficient technology.
Offers repeatable tripping action that restores conductivity after fault conditions clear.
Designed for surface or through-hole mounting via radial leads.

Applications

Overcurrent protection in portable electronic devices
Protection circuits for battery-powered equipment
Interface protection for communication ports

Procurement Notes

Verify the specific suffix designation against the manufacturer datasheet to confirm lead configuration and packaging type. Ensure the component meets required safety certifications such as UL or CSA for the target application region. Confirm thermal derating requirements are met during system integration.

Selection Notes

Select this component based on the 1.6 A hold current requirement and 72 VDC maximum voltage limit. Evaluate the 90 mΩ maximum resistance to ensure it does not cause excessive voltage drop in the circuit. Consider the physical dimensions and lead spacing for PCB layout compatibility.

Part Context

This part belongs to the Bourns Multifuse MF-RX/72 series of resettable fuses. These components utilize conductive polymer technology to provide overcurrent protection. The series offers various hold current ratings while maintaining consistent voltage and package characteristics across the family.

Replacement Considerations

Cross-reference with other MF-RX/72 series variants for different current ratings. Verify mechanical fit and electrical parameters before substituting with generic PTC thermistors. Consult official substitution guides for equivalent performance specifications.
