MF-SM050-2-006

Ptc Resettable Fuses Overview

The Bourns MF-SM050-2-006 is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse designed for overcurrent protection in electronic circuits. This specific model belongs to the SM series, characterized by its compact form factor suitable for automated assembly on printed circuit boards. It functions as a self-resetting device that transitions from a low-resistance state to a high-resistance state when subjected to excessive current or elevated temperatures, thereby limiting fault current flow. The component is engineered to provide reliable protection against short circuits and overloads without requiring manual replacement after tripping events.

Ptc Resettable Fuses Feature Summary

• Self-resetting functionality eliminates the need for manual fuse replacement after an overcurrent event
• Compact surface-mount design facilitates integration into space-constrained electronic assemblies
• Polymeric construction provides stable performance characteristics across defined operating temperature ranges

Ptc Resettable Fuses Applications

• Overcurrent protection for portable consumer electronics
• Protection of battery packs and charging circuits
• Interface circuit safeguarding in communication equipment
• General-purpose line protection in industrial control systems
