, Common Mode Chokes: CME2425-2-B Application Field and Working Principle
Common mode chokes, or CMCs, refer to a differential- mode noise-elimination component utilized in various electronic devices. Common mode chokes are used in electronic products that require both differential-mode noise filtering and common-mode noise suppression, such as in communications, metering, power systems, etc. CME2425-2-B is the world\'s highest current rating CMC available on the market, offering better common mode noise filtering performance without sacrificing the EMC. In this article, we will discuss the application fields of CME2425-2-B and how it works. Application Field
CME2425-2-B has several application fields, the most common of which are EMI reduction and interference \'mitigation. It is commonly used in areas of high electromagnetic interference (EMI); these areas include railways, aerospace, automobiles, mobile communication, and consumer electronics. In addition, the CME2425-2-B can be used for power quality improvement in power systems applications. Another application of CME2425-2-B is as an integrated board module for noise suppression in electronic products. For example, CME2425-2-B is commonly used in PC motherboards and other related consumer products. It is also widely used in high-speed digital circuits to reduce the ringing of interconnect lines. Working Principle
CME2425-2-B works by using transformer principles to suppress common mode noise in very high frequencies. The common mode choke has two parts. First is a high frequency transformer core, which is used to limit common mode current and provide a low impedance path for currents of the same polarity; second is an air gap, which is used to reduce the magnetic flux leakage in the common mode choke. The transformer core consists of two windings with the same number of turns and connected in series with each other. Each winding is connected to its own powerline. The windings are magnetized in opposite directions when power is applied and they induce opposing currents. The air gap is what allows the CME2425-2-B to filter out common mode noise from the powerline. This gap is created by two thin poles placed between the windings. When power is applied, the two poles create an air gap that restricts the passage of common mode noise. Conclusion
Common mode chokes, such as the CME2425-2-B, are an essential tool for reducing and mitigating EMI in electronic products. It works by using a high frequency transformer core and an air gap to induce opposing currents and limit the passage of common mode noise. CME2425-2-B has a wide range of applications, including power systems, communication services, and consumer electronics. In addition, it is an excellent choice for applications that require high current ratings.
