Common Mode Chokes, such as the LCFEA201202A900TG, are widely used in a wide range of applications due to their excellent filtering and low-pass capabilities. They are able to effectively reduce the high frequency currents that can corrupt data signals and cause electromagnetic interference (EMI).

The LCFEA201202A900TG common mode choke is designed to eliminate high frequency noise from data lines. It consists of two coils that are wound in opposite directions and connected to two separate conductors. The coils act as a low-pass filter, and the inductance of the composite choke is the sum of the two coils. This configuration allows the choke to attenuate high frequency noise and pass low frequency signals while blocking signals of higher frequencies.

The choke also helps reduce standing wave ratio (SWR) on the lines and thus reduce the level of distortion in data signals. The two separate coils also reduce the amount of energy that is transferred across them, so that the energy is not radiated beyond the lengths of the conductors. The choke can be used in a variety of applications where it is necessary to reduce noise, such as in telecommunications, automotive electronics, industrial automation systems, and consumer electronics.

The working principle of the LCFEA201202A900TG common mode choke is based on the principle of inductance. As current passes through the coil, it produces an electromagnetic field and a corresponding magnetic field around the coils due to electromagnetic induction. The two fields interact with each other, and this interaction creates a coil output impedance. The swaying magnetic field creates an opposing voltage drop, which acts as a low-pass filter and is able to attenuate noise and pass low-frequency signals while blocking higher frequency signals.

The LCFEA201202A900TG\'s high-performance common mode chokes offer excellent high-frequency noise attenuation, high-power handling, low insertion loss, and low-radiation coefficient. They are designed to reduce EMI and attenuate high-frequency noise in applications where the environment is extremely sensitive to these signals. They are suitable for many different applications and are available in a variety of packages and sizes.
