MF-RX012/250-T-0

Overview

The MF-RX012/250-T-0 is a resettable fuse from Bourns Inc., designed for overcurrent protection in electronic circuits. It features a hold current of 12A and a trip current of 25A, with a maximum voltage rating of 32V DC. The device operates within a temperature range of -40°C to +85°C and has a typical resistance of 1.2 milliohms. This component is engineered to automatically restore functionality after fault conditions clear.

Feature Summary

Automatic reset capability following overcurrent events
Compact surface-mount design for space-constrained applications
Low resistance to minimize power loss during normal operation

Applications

Portable electronics battery protection
Consumer appliance circuit safeguarding
Automotive accessory power lines

Procurement Notes

Verify the specific suffix 'T-0' against official Bourns documentation to confirm tape-and-reel packaging specifications. Ensure the voltage and current ratings align with your circuit requirements before procurement. Cross-reference the datasheet for thermal derating curves relevant to your operating environment.

Selection Notes

Select this component based on its 12A hold current and 32V DC rating. Consider the low impedance for efficiency-critical designs. Verify compatibility with automated assembly processes due to the surface-mount package type. Check thermal performance under expected load conditions.

Part Context

This part belongs to Bourns' MF-RX series of polymeric positive temperature coefficient (PPTC) devices. These components are widely used for secondary protection in various electronic systems where automatic recovery is preferred over manual fuse replacement.

Replacement Considerations

Consult Bourns official substitution guides for equivalent PPTC devices with matching electrical characteristics. Verify package dimensions and pinout compatibility if replacing in existing PCB layouts.
