InRush Current Limiters

TDK InRush Current Limiters are designed to limit the current at turn-on by high resistance when they are cold. These current limiters provide reduced power as the resistance decreases by a factor of 10 to 50. The InRush current limiters handle higher inrush current than fixed resistors and have the same power consumption. The TDK InRush Current Limiters current limiters are used in applications such as switch-mode power supplies and soft-start motors.
