MF-RG500-2-14

Overview

The Bourns MF-RG500-2-14 is a radial, through-hole polymer PTC resettable fuse from the Multifuse MF-RG series. It features a maximum holding current of 5 A and a trip current of 8.5 A at a rated voltage of 16 V. The device has a minimum initial resistance of 15 mΩ and a maximum post-trip resistance of 34 mΩ. It withstands a maximum fault current of 100 A with a trip time of 2 seconds. Dimensions are 10.40 mm x 3.00 mm x 14.30 mm max height.

Feature Summary

Provides automatic circuit protection by increasing resistance during overcurrent conditions to limit current flow.
Automatically resets to low resistance state after power removal and cooling, eliminating manual replacement needs.
Complies with AEC-Q200 standards for automotive grade reliability and durability.

Applications

Automotive electronics circuits requiring AEC-Q200 compliance
Overcurrent protection in consumer electronic devices
Industrial control system power lines

Procurement Notes

Verify the specific suffix -2-14 against official Bourns documentation to confirm package and tape specifications. Ensure the component meets AEC-Q200 requirements if used in automotive designs. Cross-reference datasheets for thermal derating curves before final integration.

Selection Notes

Select this model for applications requiring a 5 A hold current and 16 V rating in a radial leaded package. Consider the 100 A maximum fault current capability for surge protection scenarios. Verify that the 8.5 A trip threshold aligns with the protected circuit's operational limits.

Part Context

This component belongs to the Bourns Multifuse MF-RG series of polymer PTC resettable fuses. The series is designed for high-current applications in automotive and industrial environments. The MF-RG line offers various hold currents and voltage ratings within a standardized radial footprint.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include MF-RG500-0 and MF-RG500-AP. Other equivalents listed are 16R500GPR and PTR016V0500-BK. Verify pin compatibility and thermal characteristics before substitution.
