MF-RX110/72-AP-14

Overview

The Bourns MF-RX110/72-AP-14 is a radial leaded polymeric positive temperature coefficient (PPTC) resettable fuse from the Multifuse MF-RX/72 series. It features a hold current of 1.1 A and a trip current of 2.2 A, designed for circuits with a maximum voltage of 72 VDC. The component has a maximum rated current of 40 A and an initial resistance of 250 milliohms. It operates within a temperature range of -40°C to +85°C and utilizes a 5.1 mm lead spacing.

Feature Summary

Provides overcurrent protection through automatic resistance increase during fault conditions
Offers reusable circuit interruption without requiring manual replacement
Designed for high-voltage applications up to 72 VDC

Applications

Overcurrent protection in automotive electronic systems
Surge protection for industrial communication equipment
Circuit safeguarding in consumer electronics devices

Procurement Notes

Verify that the specific suffix AP-14 matches the required packaging configuration and lead form factor for your assembly process. Confirm the hold current rating aligns with the continuous operational load of the target circuit to prevent nuisance tripping. Ensure the maximum voltage rating exceeds the peak system voltage under all operating conditions.

Selection Notes

Select this component when a radial leaded PPTC device is required for 72 VDC systems. The 1.1 A hold current suits moderate load applications. Consider the 250 milliohm resistance for power loss calculations. Verify thermal derating requirements if ambient temperatures approach the upper limit of the specified operating range.

Part Context

This part belongs to the Bourns Multifuse MF-RX/72 series, which specializes in polymer PTC resettable fuses. The series is engineered for robust performance in harsh environments, offering cost-effective overcurrent protection solutions for various electronic industries including automotive, industrial, and telecommunications sectors.
