PT Series - Power Type NTC Thermistor NTC 8D-20: The NTC 8D-20 thermistor must be connected in series to the power circuit to avoid an inrush current when the electronic circuit is turned on. The device can effectively suppress the surge current, and after the continuous action of the current, its resistance and power consumption can be greatly reduced, and the normal working current is not affected. Therefore, a power NTC 8D-20 thermistor is the most convenient and effective tool for suppressing inrush current and protecting electronic equipment from damage. Often Used to control the inrush current of electronic equipment such as motors, heaters, valve regulators, electronic energy-saving lamps, and electronic rectifiers.
