MF-RHT200/32-AP

Overview

The Bourns MF-RHT200/32-AP is a radial leaded polymeric positive temperature coefficient (PPTC) resettable fuse designed for high-temperature applications. It belongs to the Multifuse MF-RHT series and holds AEC-Q200 automotive qualification. The device features a holding current of 2.0 A and a trip current of 3.8 A, with a maximum voltage rating of 32 VDC. It exhibits a maximum resistance of 110 mOhms and can withstand a maximum fault current of 50 A. The component operates within a temperature range of -40°C to +125°C and has physical dimensions of 14 mm in length, 9.4 mm in diameter, and 3 mm in height.

Feature Summary

• Automotive-grade reliability certified under AEC-Q200 standards
• High-temperature capability suitable for demanding thermal environments
• Radial leaded construction for through-hole PCB mounting

Applications

• Automotive electronic circuit protection
• Overcurrent protection in high-temperature industrial systems
• Battery pack protection in electric vehicles

Procurement Notes

Verify that the specific suffix AP corresponds to the required packaging configuration, such as cut tape or reel, as ordering suffixes may alter supply format without changing electrical function. Confirm AEC-Q200 certification status directly from the manufacturer datasheet to ensure compliance with automotive quality requirements before finalizing procurement.

Selection Notes

Select this component when an overcurrent protection device requires both high thermal stability and automotive qualification. The 2.0 A holding current and 32 VDC rating suit low-voltage automotive circuits. Ensure the application environment stays within the specified -40°C to +125°C operating range to maintain reliable tripping characteristics and prevent premature failure.

Part Context

This part is a member of the Bourns Multifuse MF-RHT series, which specializes in high-temperature PTC resettable fuses. The series provides robust circuit protection for automotive and industrial applications where standard components might fail due to elevated ambient temperatures. The radial leaded form factor allows for easy integration into printed circuit boards requiring through-hole assembly.

Replacement Considerations

The MF-RHT200/32-2 is a comparable variant within the same series offering similar electrical characteristics but with a different voltage rating. Verify that the alternative part meets all mechanical and thermal requirements of the original design before substitution.
