MF-RHT750-2

Overview

The Bourns MF-RHT750-2 is a radial leaded, high-temperature PTC resettable fuse from the Multifuse MF-RHT series. It features a hold current of 7.5 A and a trip current of 13.1 A at a maximum voltage of 16 VDC. The device exhibits a low initial resistance of 22 mOhms and supports a maximum fault current of 100 A. Designed for PCB mounting, it operates within a temperature range of -40°C to +125°C. Key physical dimensions include a diameter of 14 mm, height of 22.2 mm, and a lead spacing of 5.1 mm. It carries AEC-Q100 qualification and offers a power dissipation rating of 4.5 W.

Feature Summary

Provides overcurrent protection through self-resetting polymer positive temperature coefficient (PPTC) technology.
Engineered for high-temperature environments with an operational range extending up to +125°C.
Meets automotive industry reliability standards through AEC-Q100 qualification.

Applications

Automotive electronic circuit protection
High-temperature industrial equipment safeguarding
Consumer electronics overcurrent defense

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number MF-RHT750-2 with official Bourns documentation. Confirm that the specific suffix indicates the correct package type and lead configuration. Ensure compliance with AEC-Q100 requirements if deploying in automotive contexts. Validate that the radial leaded format matches the target PCB layout constraints before finalizing procurement decisions.

Selection Notes

Select this component when circuit protection requires a 7.5 A hold current and 16 VDC maximum voltage rating. The 22 mOhms resistance minimizes power loss during normal operation. Choose this model specifically for applications demanding high-temperature stability up to +125°C. The AEC-Q100 qualification makes it suitable for rigorous automotive environments where standard commercial fuses may fail under thermal stress.

Part Context

This part belongs to the Bourns Multifuse MF-RHT series, designed for robust overcurrent protection in demanding conditions. The series utilizes PPTC technology to provide resettable safety mechanisms. The MF-RHT750-2 variant specifically targets high-current applications requiring high-temperature resilience and automotive-grade reliability certification.
