Common Mode Chokes, or CMCs, are electrical components consisting of interconnected coils or windings. They are designed to counter the unwanted electromagnetic interference (EMI) of the current. A Common Mode Choke is usually used to provide power in the form of an alternating current to a device, usually through a power converter or electric motor. In this article, we will look at the 7113-RC CMC, its application fields and its working principle.

The 7113-RC CMC is an electrical component that comprises two windings. It is designed to reduce the amount of common mode (CM) current that goes through a system, while allowing differential mode (DM) current to pass through with low impedance. This reduces the amount of noise caused by the common mode current and helps protect sensitive components from external interference. Compared to many other CMCs, the 7113-RC has a high common-mode impedance and a very low differential mode impedance, making it ideal for use in applications with demanding EMI requirements.

The 7113-RC CMC can be used in a variety of applications, including in personal computers, video game consoles, digital television receivers, medical equipment, and industrial automation. It is also suitable for use in automotive electronics, power supply systems, and consumer electronics. In these applications, the CMC helps reduce the amount of interference created by common mode current and provides uniform magnetic field distribution.

The working principle of the 7113-RC CMC is based on the behaviour of the windings inside the CMC. The windings are arranged in a way that creates a magnetic field that affects both the common mode and differential mode currents. The inductance of the winding in the center of the CMC is greater than the other two windings, which results in the differential mode current flowing through the inductor at a faster rate than the common mode current. As a result, the common mode current is absorbed and reduces the amount of interference in the system, while the differential mode current passes through with low impedance.

The 7113-RC CMC offers a wide range of benefits, including improved EMI suppression and improved power efficiency. It also features a high common-mode impedance to reduce the amount of unwanted noise and interference in a system. The CMC\'s inductance also helps limit the amount of inrush current through a system and reduces the chances of transient noise.

In conclusion, the 7113-RC Common Mode Choke is an ideal choice for applications that require high EMI suppression and low differential mode impedance. It helps reduce the amount of EMI noise generated by common mode current and prevents sensitive components from interference. It also helps improve power efficiency and limits inrush current. Therefore, the 7113-RC CMC is an essential component in many systems.
