Overview
The Bourns MF-RHT900-0 is a high-temperature PPTC resettable fuse from the MF-RHT series, designed for PCB mounting with radial leads. It features a hold current of 9.0 A and a maximum voltage rating of 30 V. The device exhibits a low resistance of 7.4 mOhms and operates within a temperature range of -40°C to +125°C. It holds AEC-Q200 qualification for automotive reliability.
Feature Summary
- High-temperature capability suitable for demanding thermal environments
- Automotive-grade reliability through AEC-Q200 qualification
- Radial leaded construction for standard PCB integration
Applications
- Automotive electronic circuit protection
- High-temperature industrial power supply circuits
- Overcurrent protection in automotive battery systems
Procurement Notes
Verify the specific suffix designation when ordering, as variations such as MF-RHT900-2 exist with different voltage ratings or packaging. Confirm that the required hold current and voltage parameters match the application design before procurement. Ensure compliance with AEC-Q200 standards if the component is intended for automotive use cases requiring certified reliability data.
Selection Notes
Select this component when the application requires a 9.0 A hold current and can accommodate a 30 V maximum voltage rating. The radial leaded package is suitable for through-hole mounting processes. Consider the 7.4 mOhms resistance for minimal voltage drop in high-current paths. Verify that the operating environment stays within the specified -40°C to +125°C range for optimal performance.
Part Context
This part belongs to the Bourns Multifuse MF-RHT series, which specializes in high-temperature polymeric positive temperature coefficient devices. The series is engineered for applications exceeding standard commercial temperature limits, providing robust overcurrent protection in automotive and industrial sectors where thermal stability is critical for long-term reliability.
Replacement Considerations
MF-RHT900-2 is a related variant within the same series but carries a 16 V maximum voltage rating instead of 30 V. Substitution requires verification that the lower voltage rating meets the circuit requirements.
