Common Mode Chokes

Common mode chokes are used to attenuate any common-mode noise on a power supply, data line, or signal line. They are mainly used in power supplies, networks, and sensory signal equipment. In this article, we will discuss the application field and working principle of CM7560R-566 common mode chokes.

Application Field

CM7560R-566 common mode chokes are mainly used in power supplies, networks, and sensory signal equipment. They are used to attenuate common-mode noise on the power supply, data line, or signal line. With the choke installed, it can block the high frequency or fast switching signals from entering the power supply, data line, or signal line, thus ensuring the stability and normal operation of the equipment. In addition, these common mode chokes can be used in various types of switching power supplies, switching converters, audio systems, audio frequencies, AC/DC and DC/DC applications.

Working Principle

The working principle of common mode chokes is the same as other electrical components, in which current can only flow in one direction. As the current flows through the choke, it creates a magnetic field that has the same polarity as the current. The magnetic field induces an electromotive force (EMF) that has the same polarity and direction as the current. When an external alternating current is applied, the EMF generated by the coil is out of phase with the alternating current, resulting in opposing forces which prevents the current from increasing. This reduces EMI noise.In addition, common mode chokes also offer high impedance at certain frequencies. By adjusting the number of turns that the current needs to travel through, the impedance can be set at a particular frequency. This effectively blocks noise at this frequency and helps reduce overall noise on the power supply, data line, and signal line.

Conclusion

Common mode chokes are widely used in power supplies, networks, and sensory signal equipment. They provide high impedance at certain frequencies to reduce EMI noise, as well as attenuate common-mode noise. The CM7560R-566 common mode chokes have become increasingly popular due to their effectiveness and affordability.
