Application:
Limiting surge current, suitable for the protection of switch mode power supply, UPS power, various electric heating utensil, energy saving lights, ballast, various power circuit, colored displayer, filament protection, etc;

The function of NTC thermistor is to limit the inrush current that can kill the components in the power section during start up. An NTC thermistor has a relatively high resistance at room temperature, so at turn-on, it limits the current charging the loads rail capacitors. As the thermistor heats up, its resistance drops, so the power supply becomes relatively low impedance.
