The SL22 20007 is an inrush current limiting NTC thermistor designed to suppress surge currents in electronic circuits. It features a high cold resistance that limits current during switch-on and transitions to a low resistance state as it self-heats, maintaining power efficiency. Typical applications include power supplies, battery chargers, lighting circuits, and electric motor soft starts.
