MF-RHT900-AP

Overview

The Bourns MF-RHT900-AP is a radial leaded PTC resettable fuse from the Multifuse MF-RHT series, designed for high-temperature circuit protection. It features a 9 A hold current and a maximum voltage rating of 30 VDC. The device exhibits a low initial resistance of 7.4 mOhms and is qualified to the AEC-Q200 automotive standard. It operates within a temperature range of -40°C to +125°C and is supplied in reel packaging.

Feature Summary

• High-temperature capability with an operating limit of +125°C
• Automotive-grade reliability via AEC-Q200 qualification
• Radial leaded construction for through-hole PCB mounting

Applications

• Automotive electronic circuits requiring thermal resilience
• High-current power distribution protection
• Industrial equipment safeguarding

Procurement Notes

Verify the specific suffix 'AP' against the manufacturer's official documentation to confirm package type and availability status. Ensure the selected variant matches the required 30V rating and radial lead configuration. Cross-reference the AEC-Q200 certification requirements with your system's automotive compliance standards before finalizing the component selection.

Selection Notes

Select this component when applications demand robust overcurrent protection under elevated thermal conditions. The 9A hold current suits high-power bus lines, while the 30V rating limits its use to low-voltage systems. Consider the radial lead form factor for manual assembly or specific board layouts where surface-mount alternatives are unsuitable.

Part Context

This part belongs to the Bourns Multifuse MF-RHT series, which specializes in polymeric positive temperature coefficient devices engineered for harsh environments. The series provides reliable trip characteristics and automatic recovery, distinguishing it from standard fuses by eliminating the need for replacement after fault clearance.

Replacement Considerations

MF-RHT900-2: Radial leaded variant with 16V rating; verify voltage compatibility.
