Surface Mount Polymeric Auto Reset Polyswitch Self Resetting Fuse 30V 50mA Ih 1210 3225 Metric SMD1210-005
The main function of self -recovery fuse is to protect the effects of electrical failures such as overload, short circuit and overvoltage. They can detect whether the current in the circuit exceeds the preset current threshold. If it exceeds, the circuit will be cut off immediately to avoid problems such as overload and short circuit.
Once the current drops to the normal level, the self -recovery fuse will automatically reset, and the circuit will resume the power of power. This automatic reset function can help avoid frequent troubles to replace fuses and improve the reliability and service life of the equipment.SMD1210-005 equal to MF-USMD005 , MICROSMD005F,1210L005WR,PFUF.005.2,JK-SMD1210-005 etc.
