FSMD010-1210-R

Ptc Resettable Fuses Overview

The FSMD010-1210-R is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse manufactured by Fuzetec Technology. This component belongs to the FSMD series and utilizes a 1210 package footprint for compact circuit integration. It functions as a self-resetting overcurrent protection device, designed to interrupt excessive current flow in electronic circuits. The device operates based on polymer technology that increases resistance significantly upon heating caused by fault currents, thereby limiting current until the power source is removed and the device cools down.
