Common mode chokes, also known as common mode inductors, reduce the common mode noise in a system. They do this by introducing a magnetic flux, which generate a “common-mode” current that effectively cancels out the interference noise. Common mode chokes are most commonly used in power supplies, digital cable systems or data communications systems, but can be used in other applications, such as analog displays.

B82731M2132A030 is one type of common mode chokes. It features a high current rating of 20A and a 0.3mH inductance value. Its physical dimensions are 74.7mm (L) x 39.7mm (W) x34.3mm (H). It has been designed to meet the needs of high-power applications, such as switch-mode power supplies, and can work in an ambient temperature of up to 125℃.

The working principle of B82731M2132A030 is simple. It utilizes a ferro-magnetic core to couple signals of equal amplitude and opposite direction on the same wire, producing an opposing “common mode” current. This common-mode current has two effects. First, it cancels out the interference noise on the same wire, providing noise reduction. Secondly, it reduces voltage transients, providing voltage filtering and better surge protection.

B82731M2132A030 is especially well suited for applications in automotive, medical, lighting and automation control. It is designed to meet the specific needs of these industries, such as high temperature, high vibration, and adverse environmental conditions. In addition, the choke can be used in various industrial, consumer and commercial applications, including motor drives, electric and automotive powertrains, and displays.

In conclusion, B82731M2132A030 is a high-performance common mode choke designed for use in a variety of industries and applications. Its high current rating and the use of a ferro-magnetic core provide effective noise reduction, surge protection, and voltage filtration, making it an ideal choice for high-power applications.
