MF-RHS700-0

Overview

The Bourns MF-RHS700-0 is a radial leaded polymeric positive temperature coefficient (PPTC) resettable fuse designed for high-temperature applications. It features a hold current of 7.0 A and a trip current of 14.0 A, with a maximum voltage rating of 16 VDC. The device offers a maximum fault current capacity of 100 A and maintains a low resistance of 7 mΩ. It operates within a temperature range of -40°C to +125°C and utilizes a 10.2 mm lead spacing for PCB mounting.

Feature Summary

• Provides overcurrent protection through automatic resistance increase upon thermal activation
• Designed for reliable operation in elevated temperature environments up to 125°C
• Features radial leaded construction for standard printed circuit board integration

Applications

• High-temperature power supply circuits
• Automotive electronics requiring robust thermal stability
• Industrial control systems with high fault current demands

Procurement Notes

Verify the specific suffix and series designation against official Bourns documentation to ensure compatibility with high-temperature requirements. Confirm that the 16VDC rating and 7A hold current align with the target circuit parameters. Check for AEC-Q200 qualification if automotive application is intended, as this varies by series. Ensure lead spacing matches the PCB footprint design.

Selection Notes

Select this component when the application requires a resettable fuse capable of handling high continuous currents in thermally challenging environments. The 16VDC rating limits its use to low-voltage DC circuits. Consider the 100A maximum fault current capability for short-circuit protection scenarios. Verify that the radial leaded package fits the available board space and assembly process constraints.

Part Context

This part belongs to the MF-RHS series of high-temperature PPTC resettable fuses from Bourns. This series is engineered to withstand higher operating temperatures compared to standard PPTC devices, making it suitable for demanding industrial and automotive applications where thermal stability is critical for long-term reliability.

Replacement Considerations

Direct substitutes include other Bourns MF-RHS series variants with matching electrical ratings. Cross-reference datasheets for equivalent hold current, trip current, and voltage ratings. Ensure the replacement part supports the same maximum operating temperature and physical dimensions for proper PCB integration.
