Varistor

Zinc oxide varistor is a kind of element whose resistance value is very sensitive to the applied voltage. It is widely used in transient overvoltage protection and surge absorption of electronic and electrical equipment.

MF72 power type thermistor

MF72 power thermistor: In order to effectively suppress the surge current generated by the electronic circuit at the moment of power-on, a power NTC thermistor is connected in series in the power supply circuit, which can effectively suppress the surge current during power-on. After the surge current suppression is completed, due to the continuous effect of its current, the resistance value of the power NTC thermistor drops to a very small degree, and its own power consumption can be ignored, therefore, in the power circuit in series with the power type NTC thermistor, is the most simple and effective measures to suppress the power-on surge current protection of electronic equipment from damage. MF72 is the national standard model of power thermistor.
