Inrush current limiters (ICL) are a type of electrical device which can help to protect electrical systems from potentially damaging sudden surges of current. The ST20002B ICL is designed for applications requiring reliable and fast circuit protection. Its advanced technology provides superior performance over traditional solutions.

The ST20002B ICL is a two-terminal device that limits the peak inrush current seen upon activation or start-up of an electrical circuit. Its mechanism of action is based on the thermal characteristics of a resistor – temperature increases over time which limits the amount of current allowed flow. This allows the device to provide over-current protection while minimizing the voltage drop across the resistor\'s terminals.

The ST20002B ICL operates at very low voltage, typically less than 2V. It features a low resistance down to 0.2 Ohm, providing an efficient way of limiting inrush currents. It also has low temperature co-efficient of resistance, making it ideal for high reliability applications. The device is designed to operate within a wide temperature range from -40°C to +85°C.

The ST20002B ICL is best suited for applications such as power supplies, AC/DC converters, DC/DC converters, servers, and industrial controls. It can withstand high-voltage transients, making it suitable for use in harsh environments. The device is also capable of handling large inrush currents (up to 200A peak) and high-power (up to 25W) applications. Additionally, its rugged construction and hermetic packaging make it resistant to breakage and shorts, which ensures reliable performance over time.

The working principle of the ST20002B ICL is simple. It contains a resistor element which is sensitive to thermal changes. When an electrical current passes through the resistor an increase in temperature is created. This increase in temperature also increases the current flow resistance, thereby limiting the amount of current allowed to pass through the resistor. In this way, damaging inrush currents are prevented from flowing into the circuit.

The ST20002B ICL is a reliable and efficient device for providing over-current protection in a wide range of applications. It is easy to install and use, and its performance is guaranteed for a wide variety of conditions. With advanced features such as its low resistance, low temperature co-efficient of resistance, and hermetic packaging, the ST20002B ICL is an ideal solution for safe and reliable circuit protection.
