Common Mode Chokes

A common mode choke, abbreviated as CMC, is an electronic component consisting of an inductor and can be used to reduce common-mode noise in an electrical circuit. It is particularly useful for suppressing high frequency interference such as EMI, RFI, and power line noise. The most basic CMC consists of two or more windings of insulated wire wound around a common core. The inductance of the component is determined by the number of turns, the size of the core, and the core material. The two windings are connected to each other in series and form a single path for the current. This makes it effective at reducing common-mode noise, which is any interference that flows in both directions on a single wire or conductor.The 7120-RC model of CMC is a two-winding, common-mode, three-terminal, electrical interference suppression device used in industrial and commercial applications. This type of CMC is able to reduce interference from a wide frequency range, up to 1MHz. It operates by forming two series resonant circuits that are tuned to the frequency of the incoming interference. In order to achieve optimal suppression of the interference, the resonance circuits\' self-resonant frequency must match the frequency of the interference.The 7120-RC CMC is designed to provide superior suppression of both high-frequency and low-frequency interference. At high frequencies, the CMC creates a high impedance barrier which blocks the interference and prevents it from entering the system. At low frequencies, the CMC acts as a low-pass filter, allowing only low frequencies to pass through and reducing the intensity of the noise source.When used in a circuit, the 7120-RC CMC can reduce interference from a variety of sources including electric motors, transformers, power lines, electronic controls, and control devices. It is commonly used in industrial, commercial, and residential applications. It can also be used in noise-sensitive areas such as medical facilities and laboratories.The 7120-RC is a robust and reliable interference suppression device that is easy to install and requires minimal maintenance. It is able to reduce system noise up to 40 dB. Its design is highly efficient, allowing it to reduce costs associated with system noise by up to 75%. The 7120-RC is available in a variety of configurations, allowing for flexibility in its use.In summary, the 7120-RC common mode choke is an effective and reliable solution for reducing common-mode noise. It is popular in a wide range of commercial, industrial, and residential applications, providing optimal noise elimination at a low cost. Its design is highly efficient and able to reduce system noise up to 40 dB. It is available in a variety of configurations and can be used to reduce noise from electric motors, transformers, power lines, and other sources.
