NTC thermistors are specially developed to limit the current at turn-on by their relatively high resistance when they are cold. When the NTC thermistor heats up as a result of the current load its resistance decreases by a factor of 10 to 50, and the power it draws reduces accordingly. NTC thermistors are able to handle higher inrush currents than fixed resistors with the same power consumption.
