1. Introduction:
An NTC thermistor has to be connected in series to the power source circuit to avoid
the surge current in 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 after that through the continuous effect of
the current 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
2. Applications:
Applicable to the protection of the power circuits of conversion power supply, switching
power supply, UPS power supply, electric heaters, electronic energy-saving
lamps, electronic ballasts and other electronic devices, the filament protection
of color picture tubes, incandescent lamps and other lights
