The MS35 1R040 is a 2-pin NTC Thermistor provides a simple one-component alternative to using wire wound resistors with timers and relays. This MegaSurge MS35 series inrush current limiter thermistor has the ability to withstand high steady-state currents to 36A and up to 300J of input energy. In addition, they increase safety by eliminating the fire hazard associated with failed relays. Ideal for inrush current protection.
