Inrush Current Limiters (ICL) can be used to limit inrush current experienced when a device is powered up. The SL22 10008-A is a low temperature coefficient (LTC) Inrush Current Limiter specifically designed to help protect sensitive electronic components from inrush current. This ICL is capable of handling high steady-state current, and is suitable for use in applications with minimal power consumption, such as LED lighting.

This device can be used in a wide range of applications, from lighting control systems, HVAC, power racks and systems, to gaming machines and server systems. It is an ideal choice for applications which require a quick response time, high accuracy, low power, and stable temperature performance. It is also suitable for applications that require high accuracy current limiting or peak voltage protection.

The SL22 10008-A has a built-in Zener diode which will protect sensitive components from any overvoltage that may occur during a power surge. This can be further enhanced with a snubber network. The device also has a discharge resistor on the non-inverting side of the input voltage, which helps to reduce the inrush current. The temperature coefficient of the device ensures that it will remain constant and stable over a wide range of temperatures.

The working principle of this device is fairly simple. When the supply voltage is applied to the input of the device, the inrush current begins to rise. The Zener diode prevents excessive current from flowing by limiting the voltage across the diode. As the voltage reaches a certain level, the current flow through the device begins to decrease. This limit current is determined by the number of turns of the wire wound resistor inside the device. The temperature coefficient ensures that the current limit is maintained even as the temperature changes. Once the current has been limited to the desired value, the inrush current will not exceed this limit.

In conclusion, the SL22 10008-A is an effective Inrush Current Limiter (ICL) capable of handling high steady-state current and suitable for use in applications with minimal power consumption. This device can be used in a wide range of applications to protect sensitive electronic components from inrush current. It has a built-in Zener diode to protect against overvoltage, and a discharge resistor on the non-inverting side of the input voltage to reduce inrush current. The temperature coefficient of the device ensures that the current limiting is maintained even as the temperature changes.
