MF-RX135/72-2-14

Overview

The Bourns MF-RX135/72-2-14 is a radial leaded Polymeric Positive Temperature Coefficient (PPTC) resettable fuse from the MF-RX/72 series. It features a hold current of 1.35 A and a trip current of 2.7 A, rated for a maximum voltage of 72 VDC. The device has a maximum interrupting rating of 40 A and an initial resistance of 60 mOhms. It operates within a temperature range of -40°C to +85°C with a lead spacing of 5.1 mm.

Feature Summary

Provides automatic circuit protection through reversible resistance increase upon overcurrent or overheating events.
Utilizes polymeric material technology to maintain low impedance during normal operation while limiting fault current.
Designed for PCB mounting with radial leads to facilitate through-hole integration in electronic assemblies.

Applications

Overcurrent protection in consumer electronics power circuits
Battery pack protection in portable devices
Signal line protection in telecommunications equipment

Procurement Notes

Verify the specific ordering suffix against the official Bourns datasheet to ensure correct packaging and lead configuration. Confirm that the hold current and voltage ratings align with the target application's operational requirements before finalizing procurement orders.

Selection Notes

Select this component based on the required 1.35 A hold current and 72 VDC system voltage. Ensure the ambient operating temperature remains within the specified -40°C to +85°C range and verify that the physical dimensions fit the available PCB footprint constraints.

Part Context

This part belongs to the MF-RX/72 series of radial PPTC resettable fuses manufactured by Bourns Inc. The series offers various current ratings optimized for compact circuit protection applications requiring reliable thermal response and resettable functionality.

Replacement Considerations

Consult the official Bourns replacement guide for direct equivalents. Verify that any substitute part matches the 1.35 A hold current, 72 VDC rating, and radial lead spacing specifications to ensure functional compatibility.
