MF-LS180S

Ptc Resettable Fuses Overview

The Bourns MF-LS180S is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse designed for overcurrent protection in electronic circuits. This component belongs to the LS series, characterized by its low profile and compact form factor suitable for space-constrained applications. It functions as a self-healing device that automatically resets after the fault condition is cleared, eliminating the need for manual replacement. The device operates by increasing resistance significantly when subjected to excessive current or elevated temperatures, thereby limiting current flow to safe levels.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection against overcurrent conditions without requiring manual intervention
• Features a self-resetting mechanism that restores normal operation after cooling down
• Designed with a low-profile surface mount package for efficient board space utilization
