Procurement Notes
Verify the specific suffix configuration against official Bourns documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the selected variant meets the required AEC-Q200 qualification status for your target application environment. Cross-reference the part number with the latest Multifuse product selection worksheet to validate availability and manufacturing status before finalizing procurement plans.
Selection Notes
Select this component when circuit protection requires operation in environments exceeding standard temperature limits. The 1.6 A hold current suits moderate load protection scenarios. Ensure the 16 VDC voltage rating aligns with the system's maximum operating voltage. Consider the surface-mount package dimensions for PCB layout compatibility and verify thermal management requirements for sustained high-temperature operation.
Part Context
This part belongs to the MF-SMHT series, an expansion of Bourns' Multifuse line designed for high-temperature surface-mount applications. The series targets automotive and industrial sectors requiring robust fault protection. It complements other Multifuse products by offering enhanced thermal stability and compliance with stringent automotive qualification standards for reliable long-term performance.
Replacement Considerations
Consult the Multifuse PPTC Resettable Fuses Cross Reference Guide for verified substitute part numbers. Verify that any replacement maintains equivalent hold current, trip current, and voltage ratings. Ensure the alternative component also meets AEC-Q200 requirements if used in automotive contexts. Check package compatibility and thermal characteristics before implementation.
