Power type inrush current limiting thermistors

Product Description

Power type NTC thermistors for inrush current limiting:

• PT series NTC inrush current limiting thermistor has to be connected in series to the power source circuit to avoid the surge current at the instant when the electronic circuits are turned on. The device can effectively suppress the surge current, and its resistance and power consumption can be greatly reduced so as not to affect the normal work current. Therefore the power NTC thermistor is the most convenient and efficient instrument to curb the surge current and protect the electronic devices from being damaged.
