Inrush Current Limiters (ICLs) come in many forms, but they all work with the same basic principles. SG304 is a voltage-sensing ICL that can be used to limit inrush currents and protect components from short circuits. It is designed to be mounted directly onto printed circuit boards (PCBs), providing a reliable form of protection against overcurrents and overvoltages.

The SG304 works by sensing an external AC or DC voltage, and using this to regulate the current flow in the circuit. It does this by controlling the amount of current that is allowed to flow through a resistor connected in series with the device. The current flow is regulated by regulating the voltage across the resistor, in effect reducing the amount of current that can pass through it. When the voltage applied to the SG304 exceeds a predetermined threshold, the current is limited to a safe level.

The SG304 offers a number of advantages over other types of inrush current limiters. Firstly, it is designed to be easily attached to the printed circuit boards of any device. This means that installation is quick and easy. Secondly, it is able to detect and limit the current at much lower voltage levels than many other types of ICLs, providing protection even when the power input is relatively low. Finally, the SG304 is highly reliable and robust, withstanding temperatures up to 125°C without any adverse effect on performance.

The main application for the SG304 is to protect sensitive components from overvoltage and overcurrents. This is especially useful in areas where large transient currents may be present. For example, when switching on high-power loads such as motors, welding machines, or electric transformers. The SG304 is able to limit the peak inrush currents to these load devices, allowing them to start up safely without causing any stress to sensitive components. It can also be used in inverter and power supply applications, limiting the inrush current to reduce the risk of circuit damage.

In conclusion, the SG304 is a high-performance, reliable voltage-sensing inrush current limiter that can be easily integrated into a variety of applications. Its ability to accurately sense and limit the current at low voltages makes it an excellent choice for protecting sensitive devices and components from overloaded and short-circuited ingress currents.
