Introduction of NTC Power Thermistor:
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 to the power circuit, which can effectively suppress the surge current at startup, and after completing the role of suppressing the surge current Due to the continuous effect of its current, the resistance value of the power type NTC thermistor will drop to a very small degree, the power it consumes is negligible, and it will not affect the normal working current. Therefore, in the power circuit The use of power-type NTC thermistors is the simplest and most effective measure to suppress the surge at startup to ensure that electronic equipment is not damaged.

Strong ability to suppress inrush current
Large material constant (B value), low residual resistance
Long life and high reliability
Wide operating temperature range

Application

Suitable for switching power supply, switching power supply, UPS power supply, various electric heaters, electronic energy-saving lamps, electronic ballasts, various electronic device power circuits Protection and filament protection for color display tubes, incandescent lamps and other lighting fixtures.
