Common Mode Chokes

A Common Mode Choke (CMC) is a passive component designed to suppress electromagnetic interference (EMI) and reduce the amount of noise in a circuit. It is commonly used in circuits that require high levels of EMI control, such as signal processing and data communication systems. The B82793C0253N201 is a commercially available CMC often used in power line applications. This article will discuss the application field and working principle of the B82793C0253N201.

Application Fields

The B82793C0253N201 is designed to reduce the level of noise in both AC and DC power lines. In AC power lines, it is often used in applications such as consumer electronics, lighting systems, power supplies and motor control systems. It is also used in DC power lines for applications such as solar batteries, automotive electronics, and industrial control systems. The CMC is especially useful for filter noise generated in applications due to the high resistance of the CMC at frequencies above its cut-off frequency.

Working Principle

The B82793C0253N201 is controlled by two coils, one used for suppressing common mode noise and the other used for suppressing differential mode noise. The two coils are wound in opposite directions and are designed to cancel out the common mode noise. In addition, the CMC is designed to have strong inductance at the cut-off frequency, resulting in a high resistance value. As a result, any interference that is above the cut-off frequency will be suppressed and the noise level in the circuit will be reduced.

The B82793C0253N201 is also designed to have a wide frequency range. This allows it to effectively reduce noise across a wide range of frequencies, which is especially useful in applications that require a wide bandwidth. Additionally, the CMC has a high temperature rating, which allows it to be reliably used in applications with high heat or vibration.

Conclusion

To summarize, the B82793C0253N201 is a common mode choke designed to reduce EMI and noise in AC and DC power lines. It works by suppressing common mode noise using two coils wound in opposite directions, and by having a high inductance at its cut-off frequency. Additionally, its wide frequency range and high temperature rating make it an excellent choice for applications that require a high level of EMI control.
