Inrush current limiters (ICL) are specialized elements which allow manufacturers or users to control the amount of current drawn when first turning on an electrical device. In cases where a high startup current could damage the device or other components in the system, an ICL can be used to reduce that current, ensuring the safety of the device. This has become an important component in the electrical industry for controlling inrush current in power supplies, motor starters, home electronics and many other applications.

The SL12 40002-B is an Inrush Current Limiter which is designed to protect devices from high inrush currents which protect sensitive devices from possible damage. It serves as an efficient inrush current control device, offering superior protection and circuit optimization. The SL12 40002-B is a form, fit and function equivalent to the OD19 series products, making it the ideal replacement choice for users who require a higher level of protection from inrush current.

The SL12 40002-B features a low profile, allowing it to fit easily into compact spaces, a long life span due to its robust operating parameters, high switching power and excellent current limiting performance. It also offers an adjustable delay time, adjustable trigger voltage and high sensitivity. This combination of features makes it suitable for a wide range of applications, including power supplies, motors, home electronics, industrial equipment, automotive and medical equipment.

The SL12 40002-B features a unique two-part construction which consists of an internal resistor and a thermistor. The resistor limits the initial current when the device is powered on while the thermistor slowly ramps up its resistance to allow the current to reach the normal working level. The current limiting is achieved by rapid heat dissipation and the internal resistor carries the heat which is then transferred to the thermistor. This ensures that the current is limited gradually and accurately, while also protecting against overcurrent situations.

The SL12 40002-B is an excellent choice for any application where inrush current needs to be managed and the key advantages of the device include fast action, long life and high sensitivity which makes it suitable for a wide range of applications.
