Common Mode Chokes are electromagnetic components with two or more coils or windings wound on a common core which are used to filter out unwanted high frequency noise from the power supply or data lines. The B82721J2122N020 is a commonly used Common Mode Choke that is applied in many different applications.

Specifically, the B82721J2122N020 is designed to suppress electromagnetic interference (EMI) and is an ideal solution for EMI protection in power lines, data bus lines, control cables, and common voltage sources. It is designed with three separate windings to provide a low Impedance to the common mode current over a wide frequency range that is typically greater than 100 dB at frequencies over 200 kHz. The common mode noise filter also allows for an improved signal integrity for both DC and AC power lines as well as for applications with high-speed data transmission.

The working principle of the B82721J2122N020 is based on inductive coupling between the windings, which creates a magnetic field that opposes the movement of common mode currents. This results in discrimination between common and differential mode signals, allowing only desired signals to pass while common mode noise is filtered out. The common mode inductor also works with the differential mode inductor to reduce the total harmonic distortion (THD) and peak to peak voltage.

The B82721J2122N020 is a versatile and reliable device for suppressing EMI on power (ac and dc), data, and control lines. It is used in a variety of applications including industrial automation, motor drives, communication systems, power supplies, and light dimmers. It is also ideal for automotive, medical, and consumer electronics applications due to its wide frequency range and high suppression capability.

The B82721J2122N020 is a great product for many applications as it provides significant EMI suppression with highly reliable performance. It is a simple and cost-effective solution for the protection of power lines and data bus lines that helps to reduce the effects of electromagnetic interference and ensure the quality of signals. With its wide range of applications and reliable performance, the B82721J2122N020 is sure to be an excellent choice for any EMI protection needs.
