Common Mode ChokesCommon Mode Chokes (CM Chokes) are devices used to reduce high frequency interference in electrical systems. They are usually used to filter out harmonics, or unwanted signals, from an electrical signal source, such as a power supply. The Common Mode Choke is a three terminal device consisting of a coil, capacitor and inductor that is placed in the “common” mode of the power system. In this way, the Choke can reduce the magnitude of the high frequency interference by using an electrical circuit.The TCM1608G-350-4P is a Common Mode Choke with a 350/4P configuration. It is designed to reduce cross-talk, or interference, between two or more signal lines. The configuration consists of four ferrite cores and one slotted core, which helps to minimize the noise generated by the induction produced by the two signal lines. The TCM1608G-350-4P is frequently used to reduce EMI (electromagnetic interference) resulting from high speed networking applications such as Gigabit Ethernet or Fiber channel.A typical application of the TCM1608G-350-4P is to reduce cross talk in telecommunications networks. It has a wide operating frequency range from low DC up to 10MHz, which can help reduce the risk of interference due to high speed networking applications. The TCM1608G-350-4P is also ideal for power lines, as it can filter EMI levels resulting from high current applications.The working principle behind the Common Mode Choke is fairly simple. It uses an inductor to create a magnetic field around the two signal lines. This magnetic field will induce a signal that is opposite in phase and frequency to the two signals being transmitted. This mechanism is known as “common mode rejection”, and it is used to reduce the interference caused by the two signals.The TCM1608G-350-4P is designed with a differential mode inductance of 0.49µH, which makes it well suited for applications involving both differential and common mode noise. The half-life of the device is 7usec, which makes it suitable for long data transmission or high speed networking applications. It also has a high current capability of 2.45A, and a maximum DC resistance of 0.66Ω.In conclusion, the TCM1608G-350-4P is an important device for reducing cross talk, EMI, and other high frequency interference in electrical systems. Its wide operating frequency range, high current capabilities, and tight electromagnetic shielding makes it a valuable piece of equipment for telecommunications, data transmission, and power line applications.
