In order to avoid the surge current generated in the electronic circuit at the moment of turning on, a power NTC thermistor is connected in series in the power circuit to effectively suppress the surge current when turning on, and after the suppression of the surge current is completed, Due to the continuous action of its current, the resistance value of the power NTC thermistor will drop to a very small extent, and the power it consumes can be ignored and will not affect the normal operating current, so it is used in the power circuit The power NTC thermistor is the simplest and most effective measure to suppress the surge when starting up to protect the electronic equipment from damage.
It is suitable for the protection of conversion power supply, switching power supply, UPS power supply, various electric heaters, electronic energy-saving lamps, electronic ballasts, power supply circuits of various electronic devices, and filament protection of color display tubes, incandescent lamps and other lighting fixtures.
·Small size, high power, strong ability to suppress surge current
·The material constant (B value) is large, and the residual resistance is small
·Long life and high reliability
·Complete series, wide working range
