CME375-9

Common Mode Chokes are also known as a CME, or Common Mode EMI filter. The CME375-9 is a high performance EMI filter designed to reduce electromagnetic interference (EMI) in data and communication lines. The filter is typically used in communications and electronic equipment, such as in aircrafts, satellites, and military systems, to reduce the interference of data lines with critical systems. The CME375-9 is made up of a pair of high quality flux-coupled inductive cores, which act as a choke to reduce common mode EMI.

Common Mode EMI is a type of EMI that results from an imbalance between the power and ground connection on a data line, which is commonly found in high speed communication and electronic devices. The imbalance will cause the data and power transmission lines to become coupled, resulting in the EMI getting into the data line. This can be disruptive to the communications or electronics systems, and can result in data errors, interrupted processes, and more. The CME375-9 filter can reduce this kind of noise by providing a low-impedance path between the power line and ground.

The working principle of the CME375-9 is twofold. First, it acts as a high quality flux-coupled inductive core, which acts as a choke to reduce common mode EMI. Second, the filter works by creating two separate loops that are connected in parallel, with each of the loops having its own EMI filter. This way, any EMI that is present on one of the loops will be blocked from entering the other loop, thus reducing the overall amount of EMI present in the system.

The CME375-9 can be used in a variety of applications, such as power line suppression, ground line filtering, noise filtering, and differential line attenuation. It is also used in high speed communication systems, aircrafts, satellites, and military systems to reduce the interference of data lines with critical systems. It is also commonly used for EMI related product testing, such as EMC tests and SETI (Search for Extra-Terrestrial Intelligence) tests.

The CME375-9 is an excellent choice for reducing common mode EMI in a variety of applications. It provides both high-performance filtering and spark suppression, allowing it to reduce the amount of EMI entering and exiting the data line. In addition, the filter can also act as a low-impedance path, eliminating the need for EMI shielding. This makes the CME375-9 an ideal choice for applications where EMI is present and needs to be reduced.
