Inrush current limiters are electrical devices used to limit the amount of current entering a system at startup. These devices are designed to reduce the inrush current, which is the rapid surge of current that occurs when electrical equipment is first turned on. Inrush current limiters work by reducing the amount of current flowing into the system at startup, thus protecting the system from potential damage caused by high inrush currents.

SL22 16004 is a type of inrush current limiter (ICL) that is widely used in different industries. It is important to note that the SL22 16004 is designed for low-applied voltage applications only. It is not to be used with higher voltages, as it may not provide the desired protection or performance.

The SL22 16004 inrush current limiter consists of a thermistor element and a guard means, typically a resistor. The thermistor element is heated by the current passing through it, which causes its resistance to decrease. This in turn causes the current to be limited to a specific level resulting in an inrush current limit. The guard resistor holds the inrush current level for a certain period while the thermistor is still heating up.

The working principle of the SL22 16004 is simple. When power is applied to the load, the circuit draws large amounts of current in a very short period of time. This current passes through the thermistor, causing it to heat up quickly. The heating up of the thermistor causes its resistance to decrease, resulting in an inrush current limit. The guard resistor holds the current at the limit for a certain period while the thermistor is still heating up.

By limiting the amount of current entering the system, SL22 16004 components help to protect sensitive equipment from potential damage caused by sudden just turn-on current surges. As such, they are widely used in many industries, including telecommunications, industrial control systems, home automation systems, lighting systems, computer and data processing systems, and automotive applications.

In addition to providing protection against inrush current surges, the SL22 16004 can also be used to reduce the total power consumption in applications that require low power operation. This is because inrush current limiters can help reduce the power spikes that occur during the start-up process, resulting in more efficient and less wasteful circuit operation.

Overall, the SL22 16004 is a versatile inrush current limiter that is designed for low voltage applications. With its ability to control sudden power surges and help reduce overall power consumption, it is a widely used component for a variety of industries and applications.
