FSMD075-24R

Ptc Resettable Fuses Overview

The FSMD075-24R is a surface-mountable PTC resettable fuse from the FSMD1210 series manufactured by FUZETEC. It functions as an overcurrent protection device utilizing polymer positive temperature coefficient technology. The component provides circuit protection against excessive current conditions by increasing resistance significantly upon heating, thereby limiting current flow. It automatically resets to its original low-resistance state once the fault condition is removed and the device cools down, ensuring continuous operation without manual intervention.
