MF-NSML380/6-2

Ptc Resettable Fuses Overview

The MF-NSML380/6-2 is a surface-mount polymer positive temperature coefficient (PTC) resettable fuse manufactured by Bourns Inc. It belongs to the NSML series, designed for circuit protection in low-voltage applications. The component features a 1206 package with dimensions of 3.25mm x 1.60mm and a maximum thickness of 1.40mm. Key electrical ratings include a holding current of 3.8A, a trip current of 7.6A, a rated voltage of 6V, and a maximum fault current of 50A. It exhibits a time-to-trip characteristic of 5 seconds under specified conditions.

Ptc Resettable Fuses Feature Summary

• Polymeric construction provides rapid response to overcurrent conditions while remaining resettable after fault clearance.
• Surface mount design facilitates automated assembly and compact PCB integration.
• Concave body profile accommodates tight spatial constraints on printed circuit boards.

Ptc Resettable Fuses Applications

• Protection of portable electronic devices such as mobile phones and tablets
• Overcurrent safeguarding in USB peripheral connections
• Circuit protection for battery-powered consumer electronics

Ptc Resettable Fuses Procurement Notes

Verify that the ordered part number matches the exact suffix configuration required for your application. Confirm that the voltage rating of 6V aligns with your system's operating parameters. Ensure compatibility with surface-mount reflow soldering profiles specified in the official datasheet. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Ptc Resettable Fuses Selection Notes

Select this component when low-voltage circuit protection is required for high-density surface-mount designs. The 3.8A holding current suits applications with moderate steady-state loads. Consider the 6V rating limit for systems operating at or below this potential. The 1206 footprint offers a balance between current capacity and board space efficiency compared to smaller packages.

Ptc Resettable Fuses Part Context

This device is part of Bourns' NSML series of polymer PTC resettable fuses. The series focuses on providing reliable overcurrent protection for modern electronic circuits where space is limited. The NSML line utilizes proprietary polymeric materials to achieve fast tripping characteristics and consistent performance across various thermal environments.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes within the same series include variants with different current ratings but identical package dimensions. Cross-reference other manufacturers' 1206 PTC fuses only if electrical parameters match exactly. Verify that any replacement maintains the same voltage rating and physical footprint to ensure mechanical compatibility.
