0ZCH0050FF2G Cross Polymeric PTC Resettable Fuse Surface Mount Devices SMD1210-050 16V 3225 0.5A Concave
Resettable Self -recovery fuse is an overcurrent electron protection element. Under the condition of high -voltage, high temperature, and vulcanization reactions, it is made of special process processing under high -voltage, high temperature, and vulcanization reactions. Traditional fuse is protected only once, which can only be protected once, and it needs to be replaced after burning. The self -recovery fuse has overflowing and automatic recovery.
