MF-RG400-AP-14

Overview

The Bourns MF-RG400-AP-14 is a polymeric positive temperature coefficient (PPTC) resettable fuse designed for automotive applications. It features a radial leaded package with a maximum voltage rating of 16V and a holding current of 4A. The component operates within a temperature range of -40°C to 85°C and has a lead spacing of 5.1 mm. It complies with AEC-Q200 standards, ensuring reliability in harsh environments.

Feature Summary

Provides overcurrent protection through automatic trip and reset functionality
Complies with AEC-Q200 automotive qualification standards
Features a compact radial leaded design for easy integration

Applications

Automotive electronic circuit protection
Battery pack overcurrent safeguarding
Low-voltage DC power line protection

Procurement Notes

Verify the specific suffix 'AP' against the official Bourns datasheet to confirm it denotes the correct axial/radial lead configuration and material composition. Ensure the 16V rating aligns with the target circuit's maximum operating voltage. Confirm AEC-Q200 compliance requirements are met for the intended automotive application scope.

Selection Notes

Select this component when a low-voltage, high-current resettable fuse is required for automotive systems. The 4A holding current suits moderate load protection needs. Verify that the 16V maximum voltage rating exceeds the system's peak voltage. Consider the radial lead spacing for PCB layout constraints and thermal management requirements during fault conditions.

Part Context

This part belongs to the Bourns MF-RG series of PTC resettable fuses. The series is characterized by its automotive-grade construction and fast tripping capabilities. The MF-RG series offers a balance of performance and size, suitable for space-constrained automotive electronics requiring reliable overcurrent protection.

Replacement Considerations

Check for direct substitutes within the MF-RG series with identical 4A holding current and 16V rating. Verify lead spacing compatibility if replacing on existing PCBs. Ensure any alternative maintains AEC-Q200 certification for automotive use.
