The SL22 1R020 is an inrush current limiter (ICL) from Ametherm, part of the SL22 series. It features a resistance of 1 Ohm with ±20% tolerance and a maximum steady state current rating of 20A (up to 65°C). The component has a dissipation constant of 32.4 mW/°C and a thermal time constant of 40 seconds. Under full rated current, the body temperature reaches 187°C.
Mechanically, the SL22 1R020 has a disc body diameter of 20.0 mm (22.00 mm overall diameter) with straight leads. Lead diameter is 1.0 mm and lead spacing is 7.8 mm. The device is designed for bulk packaging with straight lead style, suitable for through-hole mounting.
This ICL is commonly used in power supply and motor drive circuits to limit inrush current during startup. The resistance decreases as the device self-heats, allowing normal operating current with minimal power loss.
