Common Mode Chokes

Common Mode Choke (CMC) is a type of device mainly used to suppress electromagnetic interference (EMI) and provide protection to systems. It works in such a way that the common mode current is blocked from entering, thus, reducing the potential for interference. CMCs are widely used in industries for controlling EMI by preventing electromagnetic radiation from escaping from power sources and other system components. CMCs are also involved in protecting electric motors from power line harmonics and other EMI sources.The CME375-8 is a commonly used type of Common Mode Choke in the industry. It is widely used in automotive, lighting, power supply, and wireless applications. It features a high current rating, low DCR, and operating temperature range from -40 to +125°C. The CME375-8 consists of two E-shaped cores with 8 windings, which are used to connect two pairs of power lines. The cores are designed to have better thermal conductivity and are made from NiZn material, which provides a better impedance matching at higher frequencies.The working principle of the CME375-8 is quite simple. It works by blocking common mode currents from entering the system, while allowing desired mode signals. It does this by incorporating the two E-shaped cores, which are connected to the two pairs of power lines. When current flows through the windings of the two cores, an induced magnetic field is generated, which creates a magnetic field around the two cores. This magnetic field induces a voltage on the two cores, blocking the common mode currents from entering the system.The CME375-8 is also designed with built-in EMC filters that further improve the performance of the CME375-8. These filters help reduce emissions of undesired signals. This helps to reduce the potential for interference that may occur between two systems.The CME375-8 is a great example of the commonly used Common Mode Choke in the industry. It is used to reduce interference caused by common mode currents and provide protection to sensitive systems. It features a high current rating, low DCR, and a wide operating temperature range. The built-in EMC filters further help to improve the performance of the CME375-8 and ensure that any undesired emissions are filtered out.
