Common Mode Chokes (CMCs) are electrical components used to suppress electromagnetic interference within an electrical power system. CMCs are also referred to as common mode filters, common mode inductors, and balanced line chokes. The CME375-9-B is a three-phase common mode choke specifically designed for applications in high performance electrical systems. The CME375-9-B is specifically designed to provide superior common mode noise cancellation while having a low system inductance of just 0.1 μH per winding.

Common mode chokes are used for a variety of purposes, including reducing electromagnetic interference (EMI) and enhancing system stability. CMCs are typically used in applications where high voltage is present and EMI reduction is desired. By using common mode chokes, the system\'s EMI susceptibility and radiated emissions can be greatly reduced. The CME375-9-B is often used in a variety of automotive, industrial, and medical applications. In addition, the CME375-9-B is also used in server rack setups, power conversion systems, and other general commercial applications.

The CME375-9-B is designed with three insulation-based coiled wires. Each of these wires is wound around a ferrite core, which allows for a high inductance value with low creepage and high dielectric strength. The diameter of the CME375-9-B is 7.6 mm, making it suitable for use in a variety of locations. The CME375-9-B is rated to 375V, making it well suited for use in high voltage power systems.

The CME375-9-B works by providing an inductive impedance to noise common to all three phases of a three phase power system. The common mode choke acts like a low-pass filter, allowing desirable power-related frequencies to pass through while attenuating common mode noise. As the frequency of the noise increases, the attenuation of the common mode noise also increases.

The CME375-9-B is designed with a low resistance value, which ensures that the device does not have an adverse effect on the system\'s power frequency performance. The CME375-9-B also features a high common mode inductance, allowing the device to effectively attenuate noise up to the MHz range. Additionally, the CME375-9-B features an insertion loss of 40dB, making it effective in attenuating undesirable frequencies.

In summary, the CME375-9-B is a three-phase common mode choke designed for use in high voltage power systems. The CME375-9-B works by providing an inductive impedance to noise common to all three phases of a three phase power system. The CME375-9-B is capable of providing superior EMI cancellation at low frequencies and high frequencies, making it an ideal choice for applications in which EMI reduction is desired. Additionally, the CME375-9-B features a low resistance value and a high common mode inductance, allowing the device to effectively attenuate noise up to the MHz range.
