Common Mode Chokes are an important class of electrical components used in modern electronics. The 7122-RC coils are among the most popular types for their versatility and reliability. They are employed in both low- and high-frequency applications, including power line filters, as well as sensitive data transmission lines.

7122-RC is a three-terminal, two-pole, ferrite-core inductor designed to reduce common mode noise in electrical systems. It has a round shape, with a single-turn winding and relatively large inductance. The windings can be made of either Cu or Ni alloy enameled wire, and the coil is usually enclosed in an epoxy or plastic housing. As a common mode choke, it works by creating a two-pole inductive reactance between two insulated coils, thus suppressing common mode noise.

The working principle of the 7122-RC chokes is quite simple. It provides a high impedance path to the common mode signals, thus blocking them from entering or leaving the system. In single-phase applications, the two coils are placed in series, while in three-phase applications, they are placed in parallel. As common-mode noise passes through the coils, it encounters the high impedance created by the inductance of the common-mode choke, which blocks the noise and prevents it from entering or leaving the system. The choke also allows the normal AC signals to pass without loss or distortion.

The 7122-RC common mode chokes are very versatile components and are commonly used in a variety of applications, such as power line filters, frequency converters, modems, radar, medical instrumentation, and more. They are also widely employed in automotive and industrial applications, such as motor control systems, switching power supplies, and digital displays. The 7122-RC is suitable for applications with frequencies up to 500 kHz.

The 7122-RC common mode chokes are incredibly reliable and offer excellent temperature stability and long-term performance. They are also relatively lightweight and easy to install. The 7122-RC is an ideal choice for applications that require high levels of noise suppression without sacrificing performance or reliability. As such, it is increasingly being deployed in a wide range of sensitive electronic systems.
