MF-RHT700-0

Overview

The Bourns MF-RHT700-0 is a radial leaded polymeric positive temperature coefficient (PPTC) resettable fuse designed for high-temperature applications. It features a holding current of 7 A and a trip current of 13 A, with a maximum voltage rating of 16 VDC. The device offers a maximum rated current of 100 A and has a typical resistance of 25 mΩ. It operates within a temperature range of -40°C to +125°C and utilizes a 5.1 mm lead spacing for PCB mounting.

Feature Summary

• High-temperature capability up to +125°C for demanding environments
• Radial leaded construction for through-hole PCB integration
• Self-resetting protection mechanism eliminates manual replacement needs

Applications

• High-temperature circuit protection in industrial electronics
• Overcurrent protection for automotive subsystems requiring elevated thermal tolerance
• Power supply input protection in consumer appliances

Procurement Notes

Verify the exact suffix against official Bourns documentation to confirm specific packaging or variant details. Ensure the selected component matches the required 16VDC rating and 125°C operating limit for your design. Cross-reference the Mouser part number 652-mf-rht700-2-14 if available, as availability may vary by region. Confirm RoHS compliance status directly from the manufacturer's datasheet before finalizing procurement.

Selection Notes

Select this component when circuit protection requires operation at temperatures exceeding standard 85°C limits. The 7A holding current suits moderate-to-high current loads where rapid response is not critical. Ensure the PCB layout accommodates the 5.1mm lead spacing. Consider the 16VDC maximum voltage constraint; higher voltage applications require different series ratings. Verify that the 100A maximum rated current meets fault current requirements.

Part Context

This part belongs to the MF-RHT series, which is specifically engineered for high-temperature performance compared to standard PPTC fuses. The 'RHT' designation indicates enhanced thermal stability, making it suitable for environments where conventional resettable fuses might fail or drift. It complements Bourns' broader portfolio of overcurrent protection devices tailored for robust industrial and automotive use cases.

Replacement Considerations

Direct substitutes include other MF-RHT series variants with matching electrical parameters. Standard MF-R series parts are unsuitable due to lower temperature ratings. Verify lead spacing and voltage ratings when considering alternative manufacturers' radial PPTC fuses.
