MF-SM100-2-006

Overview

The Bourns MF-SM100-2-006 is a Multifuse PPTC resettable fuse from the MF-SM series, designed for surface mount applications. It features a hold current of 1.1 A and a trip current of 2.2 A, with a maximum voltage rating of 30 VDC. The device has a maximum resistance of 480 mOhms and can withstand a maximum fault current of 80 A. Packaged in a 2920 (7450 metric) case, it operates within a temperature range of -40°C to +85°C.

Feature Summary

• Provides automatic circuit protection through polymeric positive temperature coefficient technology
• Offers high current interruption capability up to 80 A maximum
• Designed for surface mount installation on printed circuit boards

Applications

• Overcurrent protection in portable electronic devices
• Protection circuits in consumer electronics
• Industrial instrumentation current limiting

Procurement Notes

Verify the specific ordering suffix '-006' against official Bourns documentation to confirm reel quantity and packaging configuration. Ensure the selected variant matches the required hold and trip current specifications for the target application circuit design.

Selection Notes

Select this component when a compact SMD solution is required for low-voltage DC circuits. The 2920 package size accommodates higher current handling compared to smaller footprints. Confirm that the 30 VDC rating aligns with the system's maximum operating voltage.

Part Context

This part belongs to the Multifuse MF-SM series, which provides resettable overcurrent protection. The series is characterized by small form factors suitable for modern PCB layouts. It serves as an alternative to traditional fuses in applications requiring repeated overload recovery without manual replacement.

Replacement Considerations

Consult official Bourns substitution guides for direct equivalents. Verify that any substitute maintains the same 2920 package dimensions and electrical ratings to ensure mechanical and functional compatibility.
