Common mode chokes (CMCs) are ubiquitous components in electronic circuits, and a TF2420VU-102Y6R0-01 CMC is a type of high-frequency CMC. Its application field and working principle are discussed in detail below.

Application Field

CMCs are used in a variety of electronic applications, ranging from low-frequency and audio filters to high frequency power and communication applications. They are commonly deployed in circuits to reduce unwanted electromagnetic interference (EMI) coming from equipments or the environment. It is highly suggested to install CMCs in circuits where common mode signals need to be blocked, and in order to effectively reduce the noise, the installation of multiple CMCs is needed.

The TF2420VU-102Y6R0-01 CMC is a high frequency model and is ideal for use in a variety of applications. It is designed to attenuate common-mode currents at frequencies between 40MHz and 200MHz, making it suitable for use in WiFi/Bluetooth®, high-frequency power inverter/converter, high-frequency DC-DC converter, switch-mode power supply and high-speed motor driver circuits. It features an open circuit inductance of 1.0µH that allows the CMC to provide efficient attenuation performance in high frequency applications.

Working Principle

CMCs operate by converting the common mode currents into differential mode currents, and these converted currents are completely eliminated from the power lines. The TF2420VU-102Y6R0-01 CMC works in the same way. The CMC is composed of multiple cores with windings on each core. The windings of the core are magnetically coupled, but electrically isolated from each other. When a common mode voltage is applied to the CMC, a voltage is induced in the windings, and the voltage produces opposite polarity currents in each winding. This creates an out of phase differential mode current, and it produces a magnetic field that cancels out the generated noise current. As a result, the common mode currents are attenuated while the differential mode signals remain unaffected.

In conclusion, the TF2420VU-102Y6R0-01 CMC is a high-frequency model suitable for a variety of applications, including WiFi/Bluetooth®, high-frequency power inverter/converter, high frequency DC-DC converter, switch-mode power supply and high speed motor driver circuits. It works by converting the common mode currents into differential mode currents, which are then completely eliminated from the power lines.
