Common Mode Chokes (CMC) are magnetic components used to reduce conducted noise in signal lines. The DSO1-40-0004 CMC operates on the principle of inductive impedance, making it both a cost-effective and efficient way to control conducted noise on power and data line signals.

The DSO1-40-0004 CMC is composed of three components: a ferrite bead, a center core, and the wire used to form the coil. The ferrite bead is a cylinder of ferrite material that has a high relative permeability and low capacitance. A ferrite bead is used in CMCs due to its ability to allow signal transmission, while at the same time, limiting the passage of high frequency noise. The core provides for negligible AC resistance that creates a flux path for current through the windings. The wire used to form the coil is typically copper or aluminum and is usually coated for protection from external environmental factors.

The DSO1-40-0004 CMC works by introducing an inductor into the circuit. This inductor has a high impedance to common-mode noise and an acceptable low frequency impedance. This allows the CMC to offer excellent noise suppression across a wide range of frequencies, usually up to 80 MHz. The common-mode attenuation varies with frequency, increasing as the frequency is increased.

The DSO1-40-0004 CMC is primarily used in order to prevent the passage of high frequency noise on power and data line signals. This noise can interfere with the operation of signals, leading to potential errors or data corruption. A CMC may be used in various applications including digital communications, industrial control and automotive audio systems.

The DSO1-40-0004 CMC can also be used in order to limit the passage of transients. Transients can be caused by sudden voltage changes on the power line, overvoltage on equipment or equipment failure. CMCs can offer an effective solution for suppressing and limiting these unwanted transients.

In summary, the DSO1-40-0004 Common Mode Choke is an effective, cost efficient way to reduce conducted noise on power and data line signals. It works on the principle of inductive impedance, introducing an inductor and high impedance for common-mode noise in order to suppress noise up to 80 MHz. The DSO1-40-0004 CMC can be used in a variety of applications including digital communication, industrial control and automotive audio systems, in order to limit the passage of high frequency noise and transients.
