Common Mode Chokes: 7516-RC Application Field and Working Principle

Common mode chokes are electrical components which are designed to suppress common mode noise in electrical transmission lines. As such, they are widely used to improve the signal-to-noise ratio of audio and video systems, as well as in a variety of other applications in a range of industries. This article will examine the application field and working principle of the 7516-RC common mode choke, which is one of the most widely used products in its class.

Application Field

The 7516-RC common mode choke is primarily used in automotive, consumer electronics, and industrial automation applications. In the automotive industry, its primary use is in vehicle powertrains and chassis systems such as onboard diagnostic systems, electric vehicle charging systems, and navigation systems. In consumer electronics, the 7516-RC common mode choke is primarily used to filter interference in audio and video systems, such as TVs, amplifiers, and speakers. In the industrial automation sector, it is used primarily to suppress interference in robots, automation controllers, motor drives, and other electrical devices.

Working Principle

The 7516-RC common mode choke works by using two sets of windings to create an effective magnetic barrier. The outer windings, called a shield, create an external magnetic field which opposes the magnetic fields affecting the inner wire, called a core. The interaction between these two fields creates a magnetic imbalance which is then cancelled out by the electrical resistance, thus eliminating the majority of the common mode noise. As a result, the 7516-RC common mode choke is able to reduce the amount of noise in an electrical system by up to 30 dB.

The 7516-RC common mode choke is also very efficient at blocking out higher frequency signals, making it an ideal choice for applications that require the blocking of radio frequency signals. It is also highly durable and can withstand temperatures up to 150°C, making it suitable for use in applications where high stress and extreme temperatures are a concern.

Conclusion

In conclusion, the 7516-RC common mode choke is a highly versatile electrical component which is used in a variety of industries to reduce common mode noise and interference. Its efficiency at blocking higher frequencies makes it ideal for applications in which radio frequencies need to be blocked, while its durability and high temperature tolerance make it well-suited to applications subject to extreme stress and temperature levels. It is therefore a highly crucial component in a range of industries, and as such should be given due consideration when looking for a common mode choke to suit a specific application.
