MF-RX012/250-2

Overview

The Bourns MF-RX012/250-2 is a Multifuse Polymer Positive Temperature Coefficient (PPTC) resettable fuse designed for overcurrent protection. It belongs to the MF-RX series, featuring radial leaded construction for through-hole mounting. The device utilizes a polymer PTC element rated for operation at temperatures up to 125°C, providing robust circuit safeguarding against faults and potential damage in demanding environments.

Feature Summary

Provides resettable overcurrent protection using polymer PTC technology
Eliminates nuisance tripping caused by ambient temperature variations
Offers high resistance protection within a compact radial leaded package

Applications

Automobile circuitry protection
Overcurrent surge protection for high reliability electronic equipment
Industrial transportation systems
Communication infrastructure
Consumer electronic devices

Procurement Notes

Verify that the specific suffix '-2' aligns with the required agency approvals and packaging configuration for the target application. Confirm that the radial leaded form factor matches the PCB layout requirements. Ensure the component meets the necessary RoHS compliance standards and verify the correct datasheet version for the exact electrical characteristics of this variant.

Selection Notes

Select this component when a resettable solution is preferred over traditional fuses to allow for automatic circuit recovery after fault conditions. The radial leaded design is suitable for applications where surface mount space is constrained or through-hole assembly is mandated. Consider the 125°C polymer rating for environments requiring stable performance under elevated thermal stress without false triggering.

Part Context

This part belongs to the Bourns Multifuse MF-RX series, which provides polymer PTC resettable fuses for circuit protection. The series is engineered to reduce short circuit risks and offers cost-effective safeguarding for critical circuitry. These components are widely utilized across various industries to protect loads from overcurrent damage while maintaining flexibility in design layouts.
