Inrush Current Limiters (ICLs) are electrical components that protect against sudden and severe spikes in voltage and current. The SL22 2R018-B is a product from Renco Electronics designed to provide an open circuit voltage rating of 18V and a maximum current limit of 2.0A.

The primary function of the SL22 2R018-B is to limit the initial surge of current during equipment start-up. This type of inrush current control helps prevent circuit overload by reducing the temporarily high current associated with energizing a capacitor. By limiting the amount of current, ICLs ensure that the connected equipment is not damaged by the start-up spike.

The SL22 2R018-B is a bi-directional overcurrent device that consists of two transistors and a thermal element. The two transistors are responsible for limiting the inrush current, while the thermal element is used to rapidly power down both transistors in the event of an overload. This thermal element, known as the Thermal Shutoff Device (TSD), helps to maintain a thermal balance in the system and ensure that the transistors are rapidly shut down, and not damaged, in the event of an overload.

The SL22 2R018-B is used in a variety of applications, such as power supplies, AC/DC adapters, battery chargers, chargers, and other circuits that require protection from current inrush. It is also used in high-amperage applications, such as compressors, blowers, and induction motors. In all of these applications, the SL22 2R018-B helps to reduce the initial surge of current, providing protection against damage to the connected equipment. This helps to ensure that the equipment is not damaged during operation, and helps to extend its life span.

The SL22 2R018-B can also be used to protect against voltage surges, which can be caused by lightning, power supply switching, or other sources. By limiting the changes in current, the SL22 2R018-B helps to reduce the effect of these voltage surges, providing protection for sensitive equipment. Additionally, by reducing the energy dissipated by the circuit, the SL22 2R018-B helps to reduce the amount of heat generated in the system, allowing for greater reliability and improved overall performance of the equipment.

The SL22 2R018-B provides a reliable and effective means of limiting the inrush current, protecting sensitive equipment and ensuring reliable operation and prolonged performance. With its high tolerance rating and open circuit voltage rating of 18V, the SL22 2R018-B is an ideal product for applications requiring protection from sudden and severe spikes in current. By protecting against these types of currents, the SL22 2R018-B helps to extend the life span of connected equipment and ensures reliable operation during operation and during start up.
