Inrush Current Limiters (ICL) are devices that protect electronic components from power surges or momentary current increases. They are most often used in applications that require high inrush current, such as those involving inductive loads or those with large capacitance associated with them.

The SL10 2R005-A is one example of an Inrush Current Limiter that is relatively small in size, but is capable of limiting inrush current up to 40A. It is composed of two elements; an NTC thermistor and a current limiting resistance element. The thermistor is connected in series to the load and functions to limit the inrush current by increasing its resistance when the current exceeds a certain threshold. The current limiting resistance element then comes into play, limiting the inrush current by shorting out the thermistor once the threshold is exceeded.

One of the primary applications of the SL10 2R005-A is in automotive and industrial applications. For example, it can be used to protect against circuit failures in car batteries, power supplies, automotive electrical systems, and industrial control systems. In addition, it is suitable for a wide range of current and temperature levels, as well as a variety of voltage levels.

The working principle of the SL10 2R005-A is based on the property of a thermistor, which is a type of resistor whose electrical resistance is dependent on temperature. Using a thermistor, the SL10 2R005-A is able to detect when the current in a circuit exceeds a certain threshold, at which point the thermistor will increase its electrical resistance, thus limiting the inrush current. The current limiting resistance element then comes into play, shorting out the thermistor once the threshold has been exceeded.

In summary, the SL10 2R005-A is an Inrush Current Limiter that is designed to limit the inrush current in circuits up to 40A. It is composed of two elements: an NTC thermistor and a current limiting resistance element. The main applications of the SL10 2R005-A are in automotive and industrial systems, and it works by increasing the resistance of the thermistor when the current exceeds a certain threshold.
