MF-MSMD020-2

Ptc Resettable Fuses Overview

The Bourns MF-MSMD020-2 is a resettable polymeric positive temperature coefficient (PPTC) device from the Multifuse MSMD series. It functions as a circuit protector designed to safeguard electronic circuits against overcurrent conditions. The component operates by increasing resistance significantly when subjected to excessive current or elevated temperatures, thereby limiting current flow. Upon removal of the fault condition and subsequent cooling, the device automatically resets to its low-resistance state, allowing for repeated use without manual intervention.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection against overcurrent faults
• Features self-resetting capability after fault clearance
• Utilizes polymeric positive temperature coefficient technology

Ptc Resettable Fuses Applications
