The FSMD030-2920 is a polymeric positive temperature coefficient (PPTC) resettable fuse manufactured by RFE International. This device is designed to protect electronic circuits from overcurrent and short-circuit conditions. When an overcurrent event occurs, the PPTC fuse heats up and its resistance increases dramatically, limiting the current flow and protecting the circuit. Once the fault is cleared and the device cools down, its resistance returns to a low value, allowing normal operation to resume.

Additional Details

The FSMD030-2920 PPTC fuse has a hold current of 0.3A and a trip current of 0.6A. It is designed to operate over a wide range of temperatures and is RoHS compliant. Its small size and surface mount package make it easy to integrate into modern electronic devices. The fuse's resettable nature eliminates the need for manual replacement, reducing downtime and maintenance costs.
