Common Mode Chokes

Common mode chokes, such as the B82791G0014A016, are widely used in electronic circuitry to reduce common-mode noise and crosstalk. Common-mode chokes are usually used in parallel with inductors or capacitors to provide a low frequency cutoff, or high frequency attenuation. Common-mode chokes, as the name suggests, help suppress or filter out common-mode noise, which is generated when currents that are equal in magnitude but opposite in polarity flow through a conductor.

Application Field

Common-mode chokes are used in circuits and systems where both signal integrity and noise suppression have to be maintained. Common-mode chokes are commonly used in applications where the circuitry must be as low-noise as possible, such as signal processing, transmitters, audio amplifiers, high-precision instrumentation, and automotive systems. Common-mode chokes are also used in Ethernet and Cat 5 systems to reduce crosstalk. The B82791G0014A016 common-mode choke is used in a variety of applications, including switching power supplies, DC-DC converters, telecommunications, and automotive electronics.

Working Principle

A common-mode choke works by blocking or suppressing common-mode noise. While inductors are typically used to limit common mode noise, a common-mode choke is even better at noise suppression. This is because a common-mode choke contains multiple inductors, each of which has a dedicated core to provide enhanced common-mode noise suppression. When the B82791G0014A16 is used in a circuit, the common-mode noise is passed through the choke, where it is then filtered out or blocked. As a result, the resulting circuit is much quieter and more reliable.

In addition to blocking or suppressing common-mode noise, common-mode chokes can also be used in high-frequency applications to provide high frequency attenuation, as well as low-frequency cutoff. The frequency response and attenuation of a common-mode choke depend on its inductance, the total number of turns, and the type of core material used. By taking these factors into consideration, a common-mode choke can be designed for specific applications.

Conclusion

Common-mode chokes are widely used in electronic circuitry to reduce common-mode noise and crosstalk. The B82791G0014A016 is a popular common-mode choke used for a variety of applications, including switching power supplies, DC-DC converters, telecommunications, and automotive electronics. The common-mode choke works by blocking or suppressing common-mode noise, as well as providing high frequency attenuation and low-frequency cutoff.
