MF-RX160/72-0-14

Overview

The Bourns MF-RX160/72-0-14 is a radial leaded PTC resettable fuse from the Multifuse MF-RX series. It features a hold current of 1.6 A and a trip current of 3.2 A, rated for a maximum voltage of 72 VDC. The device has a maximum resistance of 140 mOhms and a maximum fault current rating of 40 A. It operates within a temperature range of -40°C to +85°C and utilizes kinked leads for PCB mounting with a lead spacing of 5.1 mm.

Feature Summary

Provides automatic circuit protection through positive temperature coefficient polymer technology
Self-resetting functionality eliminates the need for manual component replacement after fault clearance
Radial kinked lead configuration facilitates secure through-hole printed circuit board installation

Applications

Overcurrent protection in consumer electronics assemblies
Circuit safeguarding in industrial control systems
Protection for telecommunications equipment interfaces

Procurement Notes

Verify the specific suffix designation against official Bourns documentation to confirm exact electrical characteristics and physical dimensions. Ensure compatibility with existing PCB footprints regarding lead spacing and thermal requirements. Confirm availability status as distribution channels may vary. Cross-reference datasheet parameters with system design limits before integration.

Selection Notes

Select this component when a 1.6 A hold current and 72 VDC rating align with circuit requirements. Consider the 140 mOhms resistance impact on power loss during normal operation. Evaluate the 40 A maximum current capability against potential fault scenarios. Ensure the operating temperature range meets environmental specifications for the intended application environment.

Part Context

This part belongs to the Bourns Multifuse MF-RX series of resettable fuses. These devices utilize conductive plastic technology to provide overcurrent protection. The series offers various hold currents and voltage ratings for diverse electronic applications.
