Power NTC Thermistor Features

In order to avoid the inrush current generated in the electronic circuit at the instant of power on, a power type NTC thermistor is connected in series in the power circuit to effectively suppress the inrush current at the time of power on, and after the suppression of the inrush current is completed, Due to the continuous action of its current, the resistance of the power type NTC thermistor will drop to a very small extent. The power consumed by it will be negligible and will not affect the normal operating current. Therefore, it is used in the power supply circuit. The power type NTC thermistor is the simplest and most effective measure to suppress the surge during power-on to protect the electronic equipment from damage.

The scope of application is applicable to the conversion of power supply, switching power supply, UPS power supply, various types of electric heaters, electronic energy-saving lamps, electronic ballasts, protection of various electronic device power circuits and filaments of color display tubes, incandescent lamps and other lighting fixtures. protection.

Features:

Small size, large power, strong ability to suppress inrush current, fast response speed, large material constant (B value), small residual resistance, long life, high reliability, complete series, wide working range
