MF-SM150-2-99

Overview

The MF-SM150-2-99 is a surface-mount polymeric PTC resettable fuse manufactured by Bourns Inc. It features a rated DC voltage of 15V and a hold current (Ih) maximum of 1.5A, with a trip current (It) of 3A. The device exhibits a maximum resistance of 250mOhm and utilizes a 2-SMD package with flat terminals. This component serves as an overcurrent protection element for electronic circuits requiring compact, self-resetting safety mechanisms.

Feature Summary

Polymeric positive temperature coefficient construction for automatic circuit recovery
Surface mount design compatible with automated assembly processes
Flat terminal configuration for secure PCB attachment

Applications

Overcurrent protection in portable electronic devices
Circuit safeguarding in consumer hardware
Protection for low-voltage power supply lines

Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm availability of direct substitutes such as the SMD150F-2 from Littelfuse Inc. if original stock is unavailable. Ensure that replacement components match the required voltage, current, and package specifications to maintain circuit integrity and safety compliance.

Selection Notes

Select this component based on its 15V rating and 1.5A hold current capabilities. Consider the 250mOhm resistance impact on circuit efficiency. Evaluate the surface mount form factor against board space constraints. Verify compatibility with reflow soldering profiles and ensure the trip characteristics align with the protected circuit's fault tolerance requirements.

Part Context

This part belongs to the Multifuse series of polymer PTC devices from Bourns Inc. These components are designed to provide reusable overcurrent protection, distinguishing them from traditional one-time fuses. The series offers various voltage and current ratings to suit different application needs while maintaining a small footprint suitable for modern electronics manufacturing.
