20D _7D_ 5D_ 3D MF72 Power type NTC Thermistor Parameter

Product Item: 20D _7D_ 5D_ 3D MF72 Power type NTC Thermistor Parameter
Category: NTC
In order to avoid the surge current generated in the electronic circuit at the moment of starting. A power-type NTC thermistor is connected in series in the power supply circuit, which can effectively suppress the inrush current at startup. And after the effect of suppressing the inrush current is completed, the resistance value of the power type NTC thermistor will drop to a very small level due to the continuous effect of its current, and the power it consumes can be ignored. Will not affect the normal working current, so the use of power NTC thermistors in the power circuit is to suppress the surge at startup. The easiest and most effective measure to protect electronic equipment from damage.
