MF-RG900-AP-14

Overview

The MF-RG900-AP-14 is a PTC resettable fuse from Bourns, rated for 16V maximum voltage and 9A hold current. It features a radial leaded package with an initial resistance of 5 mOhms. The component operates within a temperature range of -40°C to +85°C and complies with AEC-Q200 automotive standards. It provides passive protection without external control logic.

Feature Summary

• Complies with AEC-Q200 automotive-grade qualification standards
• Provides passive, non-volatile circuit protection without external control logic
• Features a compact radial leaded design for through-hole mounting

Applications

• Automotive electronic circuits requiring AEC-Q200 compliance
• Overcurrent protection in low-voltage DC systems
• Consumer electronics safeguarding against short circuits

Procurement Notes

Verify the specific voltage rating (16V) against system requirements, as some similar series parts may differ. Confirm the radial lead spacing and seated height dimensions fit the PCB layout. Ensure the supplier provides the official Bourns datasheet to validate the AEC-Q200 certification status and thermal characteristics for the intended operating environment.

Selection Notes

Select this component when automotive-grade reliability is required for low-voltage applications. The 9A hold current suits moderate load protection needs. Consider the 16V limit for compatibility with 12V automotive or similar DC bus architectures. The radial package simplifies assembly compared to surface-mount alternatives for high-current paths.

Part Context

This part belongs to the Bourns MF-RG Series of PTC resettable fuses. The series is characterized by fast tripping times and robust performance in automotive environments. The MF-RG900-AP-14 specifically denotes the 9A hold current variant within this family, distinguished by its 16V rating and radial lead configuration.

Replacement Considerations

MF-RG900-2 is a listed alternative part number within the same product line.
