MF-SMHT160-2

Overview

The Bourns MF-SMHT160-2 is a high-temperature polymer positive temperature coefficient (PPTC) resettable fuse designed for surface mount applications. It belongs to the Multifuse MF-SMHT series, engineered for robust circuit protection in demanding environments. The component features a 1812 package and offers a holding current of 1.6 A with a maximum voltage rating of 16 V. It operates within a temperature range of -40°C to +125°C and complies with AEC-Q200 standards for automotive-grade reliability.

Feature Summary

• Complies with AEC-Q200 stress test requirements for automotive passive components
• Provides overcurrent and surge protection in high-temperature electronic circuits
• Features low thermal decay coefficient and high power ratings at elevated temperatures

Applications

• Protection of various automotive electrical circuits
• Overcurrent and surge protection for electronics operating at high temperatures
• Resettable fault protection for general-purpose electronic devices
• Surge protection in communication and security systems

Procurement Notes

Verify that the specific part number matches the required holding current and voltage ratings for the target application. Confirm compliance with AEC-Q200 standards if the component is intended for automotive use. Ensure the surface mount footprint corresponds to the 1812 package dimensions during PCB layout design. Check manufacturer documentation for any updates regarding RoHS compliance or material declarations.

Selection Notes

Select this component when circuit protection is required in environments exceeding standard temperature limits. The 1.6 A holding current suits moderate load protection scenarios. The 16 V maximum voltage rating restricts usage to low-voltage DC applications. Consider the 1812 SMD package for space-constrained designs requiring automated assembly compatibility.

Part Context

This device is part of the Bourns Multifuse MF-SMHT series, an expansion of their high-temperature PPTC resettable fuse lineup. The series targets automotive and industrial applications requiring reliable protection under thermal stress. It complements other Bourns protection products by offering a compact, self-resetting alternative to traditional fuses in modern electronic assemblies.

Replacement Considerations

Consult the official Multifuse cross-reference guide for verified substitutes. Ensure replacement parts maintain equivalent AEC-Q200 certification and thermal performance characteristics.
