TDK Inrush Current Limiters (ICL) are designed to handle higher inrush currents compared to fixed resistors while maintaining similar power consumption. The Inrush Current Limiters achieve this by presenting high resistance when cold, which limits the current during startup. As the component warms up, its resistance decreases significantly by a factor of 10 to 50, leading to reduced power consumption. These limiters find common use in switch-mode power supplies and soft-start motors.
