Inrush Current Limiters (ICLs) are a type of device used to limit and control inrush current during the power-up of a capacitor, motor, transformer, or other system by monitoring changes in voltage. The SL18 10005-A ICL from Vishay Electro-Films is a volumetric encapsulated electronic switch designed for inrush current control, overvoltage protection, and noise suppression.

The device consists of two MOSFET transistors connected in series, a DC blocking capacitor, and active inrush current control circuitry. During normal operation, the device is a low impedance with a capability of up to 35A. The device contains built-in protection circuitry to prevent overcurrent, and can handle large transients up to 5,000V. The SL18 10005-A can also be configured to provide noise suppression and distortion correction when used in conjunction with a matching circuit.

In operation, the SL18 10005-A monitors the line voltage and current flowing in the system to determine the magnitude of the inrush current. If the level of current is greater than the device\'s rated nominal current limit, the SL18 10005-A will detect the overcurrent and automatically reduce the voltage. This will result in a corresponding reduction in power and current, preventing the overload that would otherwise occur. This feature makes the device ideal for use in motor start-up applications and other systems that may experience large inrush currents.

The SL18 10005-A also contains built-in temperature protection, ensuring proper operation in all environments. The device is rated for a temperature range of -20°C to +85°C, and has built-in self-test capability to alert users of any potential failures. Additionally, the device is RoHS compliant, and is UL recognized and CE certified.

The SL18 10005-A is an ideal solution for applications that require protection from inrush overcurrents and overvoltage transients. With its built-in safety features, the device ensures protection of connected systems, as well as providing noise suppression and distortion correction in selected applications.
