MF-MSMF030 Resettable PPTC Fuse (300mA, 30V, 1812)

The MF-MSMF030 is a self-resetting PPTC fuse designed to provide reusable overcurrent protection for electronic circuits. It has a 300mA hold current and supports circuits up to 30V DC in a compact 1812 surface mount package. During an excessive current condition, the device increases its resistance to restrict current flow and automatically returns toward its normal low resistance state after the fault is removed and the device cools.
