Common Mode Chokes

CM2824E702R-10 is one type of common mode chokes, and is widely used in many applications. Common mode chokes are electrical components designed to reduce electrical noise by blocking conducted radio frequency (RF) noise from flowing through the power supply. They work by creating an inductive barrier between multiple power sources.

CM2824E702R-10 Application Field

CM2824E702R-10 is commonly used in electronic systems such as communications equipment, signal processing, and audio/video equipment. It is also useful in automotive and industrial electronics. Common mode chokes block interference between inductive devices such as motors and large capacitors, helping to maintain system integrity and improve transmission speed.

In general, the application areas of common mode chokes are:

• Automotive applications: Commonly used in engine and ignition systems.
• Electronic systems: Commonly used in computers, consumer electronics, and medical equipment.
• power supplies: Commonly used in LED lighting, power conditioning, industrial controls, and HVAC systems.

Working Principle

A common mode choke is a type of inductor that is used to reduce the amount of conducted electromagnetic interference (EMI) in a system. The inductor consists of two separate coils wound in opposite directions. The first coil is connected to the power source, and the second coil is connected to the load. When an alternating current flows through the coils, an electromagnetic field is created. The two fields interact to create a cancelling field, which blocks the conducted EMI.

When an interfering signal is present, the coils will cause the inductive reactance of the signal to increase. This phenomenon is known as inductive cancellation. The greater the inductance, the greater the cancellation effect. As a result, the amount of EMI reduced is proportional to the inductance of the choke.

Common mode chokes can also be used to reduce common mode noise from the power supply. This type of noise is caused by the interaction of the power and ground lines of the system. By connecting a common mode choke between the power and ground lines, the interaction can be reduced and the noise eliminated.

Conclusion

CM2824E702R-10 is a type of common mode choke. It is useful in a number of applications, including automotive, industrial, and consumer electronics. Its working principle is based on the inductive cancellation effect, which helps to reduce EMI in a system. By connecting a common mode choke between the power and ground lines, it is also possible to reduce common mode noise.
