Common Mode Chokes (TCM1210-650-2P) – Application Field and Working Principle

Common mode chokes are a type of electrical filter which is used to suppress common mode interference in transmission lines. The most common of these chokes are used in high-speed communication and on-board signal processors, especially in Automobile electronics, medical instruments and industrial manufacturing systems.

The TCM1210-650-2P is a common mode choke designed and manufactured by Coilcraft which has a wide range of application fields. It can be used in applications such as power line filtration/isolation, data line isolation, and for reducing EMI/RFI noise. It is primarily suitable for the filtration of Automobiles, medical instruments, industrial manufacturing systems, OA systems and audio-visual systems.

The basic structure of the TCM1210-650-2P consists of two windings that are wound around a ferrite core. It can be adjusted to reduce EMI/RFI noise levels to a minimum. The two windings are connected in series and their inductance is designed to minimize the impedance levels of common-mode noise signals. This reduces the levels of interference and other unwanted noises that may be present in the line.

When using the TCM1210-650-2P, the input signals are applied to the first winding and the output signals to the second winding. The common-mode current travels through both windings but is blocked by the choke while the differential signals travel through only one of the windings. This suppresses the common-mode signals and allows differential signals to pass unaffected.

The benefits of using the TCM1210-650-2P are quite high. By reducing the level of common-mode noise, better performance by the device is achieved and thus increases efficiency. It is also proven that the TCM1210-650-2P can also reduce the number of errors and glitches that occur in communication, which in turn reduces the risk of data loss and enables smoother communication.

In conclusion, the TCM1210-650-2P is an ideal choice for applications that require the suppression of common-mode noise. Its wide range of features and benefits make it suitable for a number of high-speed communication and on-board signal processors, increasing their performance and efficiency.
