NTC Thermistor： ： Application Note Inrush current suppressing Circuits including a capacitor, filament for a bulb, inverter for fluorescent lamp, a heater and etc., induce an inrush current more than 100 times the normal current when the circuit switch is turned on. The NTC thermistors specially developed for this application limit the current at turn-on by their relatively high cold resistance. During continuous operation, the NTC thermistors heats up and its resistance remains negligibly low. I T Example 1. 2.
