Inrush Current Limiters (ICLs) are devices used to manage the inrush current that is caused when an electrical circuit is connected to an AC power source. These devices are designed to reduce the amount of power a system draws from the power source, limiting the surge of current that is caused by the circuit\'s capacitive or inductive reactance. One type of ICL that is commonly used in AC power systems is the SL22 5R012-BT.

The SL22 5R012-BT is a low-cost inrush current limiter that can be used in a wide variety of applications. It is designed to handle varying load currents and peak inrush currents of up to 12 amps. The device has an ultra low resistance, which helps reduce the power loss that is inherent in limiting peak current. Additionally, its patented thermal compensation circuit helps provide consistent temperature protection. This makes it suitable for applications that require greater stability in the current limit.

The SL22 5R012-BT\'s operating principle is based on a fast-acting, temperature-controlled solid state switch. The device is designed to monitor the voltage and current levels on the circuit it is connected to, and to open and close the switch in response to changes in those levels. When the current level reaches a preset limit, the switch is instantly opened, reducing the inrush current to acceptable levels.

The SL22 5R012-BT has an operating temperature range of -40 to 85°C and a maximum peak current of 12 amps. Additionally, it has a peak hold time of 150 μs, and a maximum leakage current of 30mA. It is designed to be easily mounted onto a circuit board and comes with a variety of options, including an optional over-voltage protection circuit and a snubber circuit.

The SL22 5R012-BT is designed for use in a variety of applications including heavy-duty power supplies, LED drivers, high-power inverters, welding machines, and motor control equipment. Its low cost and reliable performance make it an ideal choice for any type of application that requires an inrush current limiter.

In summary, the SL22 5R012-BT is a reliable and economical inrush current limiter that can be used in a wide variety of AC power systems and applications. Its fast-acting temperature-controlled switch and patented thermal compensation circuit help ensure consistent protection from peak current inrush. Additionally, its low cost and easy installation make it an ideal choice for any project that requires an ICL.
