。It consists of a current-limiting resistor connected between the power supply and the load, and a delay-operation type switch circuit that short-circuits the current-limiting resistor. Prevent inrush current when the power is turned on by connecting the current limiting resistor between the power supply and the load only until the switch circuit operates and the current limiting resistor is shorted. In the inrush current prevention circuit, the current limiting resistor is a heat sensitive resistor having a required initial resistance value and exhibiting a large positive temperature coefficient.
