Common Mode Chokes

Common Mode Chokes (CMCs) have become an important electrical component in many systems and applications. They are used to reduce electromagnetic interference (EMI) caused by common mode currents in electrical devices. The RN222-1-02-18M is one example of a CMC, and is widely used in a variety of applications. This article will discuss the application field and working principle of the RN222-1-02-18M CMC.The RN222-1-02-18M CMC is used in a variety of applications, including automotive, medical, consumer, and industrial systems. In automotive applications, it is used to reduce EMI from engine and motor control systems, as well as from the exterior lights and other electronic components. In medical applications, it is used to reduce EMI associated with pacemakers, x-ray machines, and other medical systems. Consumer applications include cameras, audio equipment, gaming systems, and other electronic goods. Finally, the RN222-1-02-18M CMC is used in a variety of industrial applications, including robotics, machine control, power supplies, and lighting systems.The working principle of the RN222-1-02-18M CMC is based on the principle of inductance. This CMC is designed to block common mode emissions while allowing normal operation of the primary circuit. The RN222-1-02-18M consists of two separate coils that are connected in series. The two coils have equal inductance and are placed on the opposite sides of the primary circuit. When an AC signal is applied to the primary circuit, the two coils produce an inductance that blocks the AC signal, thus reducing EMI.The RN222-1-02-18M has a low DC resistance and a high-inductance response. This allows it to block the common mode emissions while allowing the signals to pass through the primary circuit. The RN222-1-02-18M also has a high operating temperature range, making it suitable for use in high-temperature environments. The device also has a high self-resonance frequency, which helps reduce the distortion caused by the common mode currents.In summary, the RN222-1-02-18M CMC is a widely used device that is used to reduce EMI associated with common mode currents. This CMC consists of two coils which are connected in series to block the AC signal while allowing normal operation of the primary circuit. The RN222-1-02-18M also has a high operating temperature range and a high self-resonance frequency, making it a suitable choice for a variety of applications.
