Bourns MF-RM Series

Bourns MF-RM series of PTC resettable fuses feature a resettable functionality with overtemperature and overcurrent protection that can save expensive components from having to be replaced after tripping. Additionally the MF-RM series are faster than bimetallic switch designs and generally suffer less from electromagnetic interference. With a reduction in repair and replacement costs, as well as less nuisance tripping, the MF-RM series is ideal for a variety of applications such as food blenders, coffee machines, HVAC. electric fans and blowers and AC adapters.
