MF-RX110-AP

Overview

The Bourns MF-RX110-AP is a radial leaded polymer positive temperature coefficient (PPTC) resettable fuse from the Multifuse MF-RX/72 series. It provides overcurrent protection with a hold current of 1.1 A and a trip current of 2.2 A at ambient conditions. The device supports a maximum voltage of 72 VDC and can interrupt fault currents up to 40 A. It features a typical resistance of 250 mOhms and operates within a temperature range of -40°C to +85°C. The component utilizes a bulk packaging format.

Feature Summary

Provides automatic circuit recovery after fault clearance without manual replacement
Offers robust protection against short circuits and overcurrent events in demanding environments
Eliminates nuisance tripping caused by ambient temperature variations

Applications

Overcurrent protection for automotive electronic circuits
Surge protection for high-reliability industrial equipment
Fault protection in communication and security systems

Procurement Notes

Verify the specific suffix designation, as AP variants may differ in packaging or compliance documentation compared to standard suffixes. Confirm that the radial lead configuration matches the target PCB footprint requirements. Ensure the 72VDC rating aligns with the system's maximum operating voltage under all transient conditions.

Selection Notes

Select this component when a radial leaded form factor is required for through-hole mounting. The 1.1A hold current suits moderate load applications. Verify that the 40A maximum interrupting capacity exceeds the prospective fault current available at the installation point within the circuit design.

Part Context

This part belongs to the Bourns Multifuse MF-RX/72 series, designed for high-voltage and high-temperature resilience. The series utilizes advanced polymer PTC technology to deliver cost-effective circuit safeguarding. It serves as a reusable alternative to traditional one-time fuses in space-constrained layouts.
