Common Mode Chokes

Common mode chokes (CMCs) have become increasingly popular for current applications because of their ability to reduce common-mode currents. CMCs are inductors that are specifically designed to provide an electrical imbalance between the two coil windings, thereby significantly reducing the amount of common-mode current that can flow. 7112-RC is a type of CMC that has become a standard for many applications, especially those that require a high degree of shielding. In this article, we will discuss the 7112-RC\'s application field and working principle, as well as the benefits of using it.

Application Field of 7112-RC

7112-RC is an ideal common mode choke for applications where high levels of common-mode current need to be reduced, such as those involving long runs of low-impedance cable. It is also suitable for applications that require shielding from EMI, such as communications equipment, consumer electronics, and motor control systems. 7112-RC also has the advantage of reducing the overall power consumption of a system due to its low resistance. This makes it an excellent choice for applications in which a high level of performance is desired in a compact package.

Working Principle

7112-RC works by utilizing a pair of coils that are wound in opposite directions. This causes the two coils to have a "reverse polarity push-pull" effect, which significantly reduces the amount of common-mode current that can flow. The coils of the 7112-RC are also designed to be tightly coupled, which increases their effectiveness in cutting off the common-mode current.

Benefits of 7112-RC

Using7112-RC has many benefits. First, it is a highly reliable product that is well-suited for a variety of industrial applications. It is also highly efficient in reducing common-mode currents, which leads to lower power consumption and improved system performance. Additionally, because of its compact package, it is easy to install in tight spaces. Finally, it is available in a variety of sizes and configurations, making it easy to find the right CMC for any application.

Conclusion

Common mode chokes are an important component of any modern electronic system, and 7112-RC is a promising option for those looking for a reliable, high-performance CMC. Its wide range of benefits make it an ideal choice for applications requiring significant reduction of common-mode currents, shielding from EMI, and low overall power consumption. 7112-RC is an excellent way to ensure that your system is running as efficiently as possible.
