Common Mode Chokes
Common mode chokes, such as LCFA201202A900TG, are frequency-dependent inductances that are used in electronics to reduce or eliminate noise. They act as filters that prevent interference from other electronic components or devices, and are commonly used in power supplies and signal transmission systems.
Application Field
Common mode chokes are used in a variety of applications where EMI (electromagnetic interference) suppression is necessary or preferred. Firstly, they can reduce or eliminate EMI on printed circuit boards, as well as minimize the cross-talk between signals due to EMI. Secondly, they reduce the power of the EMI interference to electrical and electronic devices, such as those in automobiles, motor control systems, and telecommunication equipment and systems. Finally, they are also commonly used in digital multimedia systems, medical equipment, and consumer electronics.
Working Principle
Common mode chokes operate by restricting the flow of alternating current, also known as AC, while allowing direct current, also known as DC, to flow through. This is done through the use of inductance, which is a property of the choke that prevents the flow of AC. The choke works by restricting the flow of currents in such a way that it will reduce the intensity of any EMI that could interfere with other electronic components.
Common mode chokes, such as LCFA201202A900TG, consist of two or more coils of wire wrapped around a ferromagnetic core. This core then acts as a shield to help reduce the bandwidth of the EMI, thus preventing or reducing interference from the outside. The coils are connected in either an “L” or a “T” configuration, with the “L” configuration being the most common. In this configuration, the two coils are wound in opposite directions, so that the magnetic fields generated by each coil cancel each other out. This helps to reduce the amount of EMI emitted by the choke.
Conclusion
Common mode chokes, such as LCFA201202A900TG, are widely used in a variety of applications where EMI suppression is necessary or preferred. Through the use of inductance, they can restrict the flow of AC (alternating current) while allowing the flow of DC (direct current). They can also reduce or eliminate EMI on printed circuit boards, as well as minimize the cross-talk between signals due to EMI. Finally, they are commonly used in digital multimedia systems, medical equipment, and consumer electronics.
