Common-mode chokes are a form of electronic component used to suppress common-mode interference in signal cables. The B82793S0253N201 is a type of common-mode choke designed to provide high common-mode impedance and low insertion loss for high-frequency signals up to 2 GHz. It features low insertion loss, high current handling, and low parasitics, making it an ideal choice for applications where high-frequency interference cancellation is critical.

The B82793S0253N201 consists of an inner and an outer loop of a single winding. The inner loop is wrapped around a ferrite core and carries the signal current, while the outer loop acts as a shield and carries the return current. This design allows for high common-mode impedance and low insertion loss over a wide frequency range. The device is also equipped with a matching capacitor that compensates for core losses and improves high frequency attenuation.

The B82793S0253N201 is well suited for applications where interference cancellation is of critical concern, such as high-speed digital data communications. These devices are typically used to provide differential mode and common-mode noise attenuation in cables, thus ensuring reliable data transmission and reception. They can also be used to reduce RF interference in low-frequency applications, such as radio receivers. Other applications may include power line filtering, cable filtering, and antenna matching.

In operation, the B82793S0253N201 provides high common-mode impedance and low insertion loss by leveraging Faraday’s law of induction. The device works by creating a magnetic field in the ferrite core when the signal current flows through the inner loop winding. This field induces a voltage on the outer loop winding, which is used to provide a path of return current. This “magnetic leakage flux” effectively eliminates common-mode interference in the cables, while allowing the desired signal to pass through unaffected.

In summary, the B82793S0253N201 common-mode choke is a high performance device designed to provide effective interference cancellation for high-frequency signals. It has an integrated ferrite core, and utilizes Faraday’s law of induction to provide high common-mode impedance and low insertion loss. The B82793S0253N201 is well suited for applications in high-speed digital data communications, radio receivers, power line filtering, cable filtering, and antenna matching.
