Common Mode Chokes refer to the electrical components which are developed for the purpose of suppressing Common mode interference. It suppresses the transferred signal noise on the power line by utilizing inductance. Common Mode chokes are utilized in a wide diversity of fields such as fueling equipment, communication data lines, home networking systems， industrial equipment, automotive electronic systems, and robotics.

One example of a popular Common Mode Choke is the RT8522-20-3M0. This is a common mode choke that offers superior performance suppressing common-mode noise generated on the power line. Unlike traditional low-frequency chokes, the RT8522-20-3M0’s effective common-mode noise suppression extends to an operating frequency of up to 100MHz. Its high efficiency helps to reduce the inductor size while providing the same level of reliable noise suppression.

The RT8522-20-3M0 features three independent inductors in a single shielded package. This allows it to effectively suppress common-mode interference in multi-point bus systems. The device can be used in many different applications by taking advantage of its excellent characteristics, such as high DC insulation resistance, high current-carrying capacity, and excellent temperature stability.

The working principle of the RT8522-20-3M0 is based on three physical phenomena. The first phenomena is magnetic induction, where the three inductors combined with the shield creates a magnetic field that can produce a voltage in response to current. The next effect is magnetic flux, which is the result of the magnetic field created by the three inductors and shield. This flux results in the flow of electrons through the shield and then induces a voltage in the shield. Lastly, the third phenomenon is eddy currents, which form around the conductive surfaces inside the shield. These eddy currents generate opposing magnetic flux, which helps to reduce any common-mode interference that may be present on the line.

The RT8522-20-3M0 can be used in a wide variety of applications, such as power supplies, inverters, fuel pumps, motor controllers, and more. It is ideal for applications where high current carrying capacity and high insulation resistance is needed. Furthermore, the RT8522-20-3M0 is particularly suitable for application in vehicles, as it is both rugged and durable.

In conclusion, the RT8522-20-3M0 is a highly effective Common Mode Choke that is used in many applications for noise suppression. By utilizing physical phenomena such as magnetic induction, flux, and eddy currents, the RT8522-20-3M0 is able to effectively reduce any common-mode noise present on the power line. This ensures that the end result is a clean and reliable signal, which is essential for many applications. By utilizing the RT8522-20-3M0, users can significantly reduce the size, weight, and cost of their product, while guaranteeing reliable and clean results.
