Inrush Current Limiters (ICLs) are designed to protect electronic components, including semiconductors, capacitors, motors, relays, and lighting from damaging inrush current. They are used to limit the amount of current that can flow into the electronic component during start-up, allowing the component to start up safely without risk of damage or failure. The SL15 40004-A is a common ICL that is used in a wide range of applications.

The SL15 40004-A is a unipolar ICL with a current limiting range of 6A maximum. Its linear thermal characteristics maintain the inrush current even with voltage fluctuations. The device can be used with any voltage between 10V and 60V, and it is designed to be used in conjunction with power supplies or other high current devices where the inrush current can cause damage.

The SL15 40004-A is typically used in applications where high inrush currents may occur. Common applications include motor starters, solenoid-operated valves, compressed gas cylinders, circuit protection, and medical equipment. It is also suitable for use in low-power applications such as electronic toys, automotive components, and AC power adapters.

The SL15 40004-A utilizes a simple yet effective working principle. The ICL contains a resistive element in its core that limits the flow of current to the device. When the device is switched on, the element provides a throttle on the current, limiting the max current allowed to flow into the device. This protects the device from damage resulting from excessive current caused by inrush.

In addition to protecting electronic components from inrush current, the SL15 40004-A can also be used to reduce harmonic distortion and noise. Because its resistive element limits the amount of current that can flow into the device, the distortion and noise created by the voltage fluctuations is substantially reduced. This allows the component to operate more efficiently while reducing interference in the electrical system.

Overall, the SL15 40004-A is an effective and reliable ICL that can be used in a wide range of applications. Its current limiting range and linear thermal characteristics make it an ideal choice for high current applications, while its ability to reduce harmonic distortion and noise makes it suitable for use in low-power electronics. With its simple working principle and easy installation, the SL15 40004-A is a great choice for protecting electronic components from potentially damaging inrush current.
