MF-RX014/250-2

Overview

The Bourns MF-RX014/250-2 is a resettable polymeric positive temperature coefficient (PPTC) device designed for overcurrent protection in electronic circuits. It features a hold current of 14A and a trip current of 25A, operating within a voltage range up to 60VDC. The component utilizes a radial leaded package configuration, suitable for through-hole mounting on printed circuit boards. Its construction involves a polymer matrix filled with conductive particles that increase resistance significantly upon thermal activation during fault conditions.

Feature Summary

Provides automatic circuit recovery after fault clearance without manual replacement
Offers reliable overcurrent protection through thermal response mechanisms
Designed for compact through-hole integration in space-constrained applications

Applications

Battery pack protection systems
Consumer electronics power input stages
Industrial control board overcurrent safeguarding

Procurement Notes

Verify the specific suffix codes against manufacturer documentation to confirm exact electrical ratings and packaging configurations. Ensure compatibility with peak pulse current requirements and maximum working voltage limits for the target application environment. Cross-reference datasheet specifications for ambient temperature derating curves before finalizing procurement decisions.

Selection Notes

Evaluate the hold current threshold relative to normal operating loads to prevent nuisance tripping. Assess the trip current capability against potential surge currents present during startup or transient events. Confirm that the physical dimensions and lead spacing align with the intended PCB layout constraints and assembly processes.

Part Context

This component belongs to Bourns' MF-RX series of resettable fuses, which are engineered for high-reliability protection in various electronic assemblies. The series offers multiple current ratings and package options to suit diverse design requirements. These devices serve as cost-effective alternatives to traditional one-time fuses in applications requiring repeated fault tolerance.
