MF-RG900-2-14

Overview

The Bourns MF-RG900-2-14 is a radial leaded PolySwitch resettable fuse designed for overcurrent protection in electronic circuits. It features a hold current (Ih) of 9A and a trip current (It) of 15.3A, with a maximum voltage rating of 16VDC. The device can withstand a maximum fault current of 100A. This component utilizes positive temperature coefficient technology to provide automatic circuit interruption during overload conditions, offering reliable protection without the need for manual replacement after tripping.

Feature Summary

• Provides automatic resettable overcurrent protection using PTC technology
• Radial leaded package facilitates through-hole mounting on printed circuit boards
• Capable of handling high fault currents up to 100A for robust circuit defense

Applications

• Consumer electronics power supply input protection
• Portable device battery circuit safeguarding
• Industrial control board overcurrent limiting

Procurement Notes

Verify the specific suffix -14 corresponds to the required lead configuration and packaging format. Confirm that the 16VDC voltage rating aligns with the target circuit's operating parameters. Ensure thermal management considerations are addressed, as resettable fuses require adequate airflow or spacing to dissipate heat effectively during normal operation and recovery phases.

Selection Notes

Select this component when a 9A hold current is required for low-voltage applications. The 16V rating limits its use to low-voltage DC systems. Consider the 15.3A trip threshold for precise overload detection. Evaluate the physical size constraints of the PCB layout against the radial leaded form factor. Compare performance requirements against higher voltage or current rated alternatives if system demands exceed these specifications.

Part Context

This part belongs to the Bourns MF-RG series of resettable fuses, which are widely used for circuit protection. The RG series typically offers compact solutions for consumer and industrial electronics. The MF-RG900-2-14 variant specifically targets high-current, low-voltage applications requiring reliable, non-fusing protection mechanisms.

Replacement Considerations

Direct substitutes must match the 9A hold current, 16V rating, and radial leaded package. Verify that alternative PPTC devices meet or exceed the 100A maximum fault current capability. Ensure compatibility with the 15.3A trip current threshold to maintain circuit protection integrity.
