MF-FSML100/8-2

Ptc Resettable Fuses Overview

The Bourns MF-FSML100/8-2 is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse from the MicroFuse series. It features an 8V rated voltage and a 100mA hold current, designed for overcurrent protection in compact electronic assemblies. The device utilizes a polymer composite that increases resistance significantly upon overheating caused by excessive current flow. This component is engineered for high-reliability applications requiring fast response times and low power consumption within tight space constraints.
