Common Mode Chokes (CMCs) are used to reject common mode electromagnetic interference (EMI) between two or more conductors. Typically, these devices are found in applications where there is a need to reduce the susceptibility to EMI and other electrical noise phenomena. The CM1011-105 is a critically designed CMC to be used in many applications requiring precise, low-loss filtering of common mode noise. It is primarily an inductive device, although it may include a capacitor for high-frequency rejection.

The CM1011-105 consists of a pair of inductors wound in parallel, usually in a proprietary winding pattern to reduce the common mode inductance. It is designed to operate effectively over a wide frequency range from 10 kHz to several hundred megahertz, depending on size and application. The winding material and orientation, as well as the number of turns, can be customized to suit various applications.

This CMC is typically used in power supplies, motors, and other high-power induction motors, as well as in Ethernet data communication systems, which use a pair of twisted conductors to transfer data. In addition, it is used to reduce the effect of EMI interference in the form of electrostatic noise, radiation, and conducted noise. It is also used in pulse, audio, and video applications.

The CM1011-105 works to filter out common mode noise that has been generated within the system. This is done by providing both inductance and capacitance in the CMC. The inductance provides isolation between the two conductors by providing a barrier, while the capacitance provides a balanced shunt which helps to absorb any EMI signals that are present.

The CM1011-105 also provides a small amount of current in the form of a bypass current which helps to further reduce EMI. In addition, it is designed to provide a very low common mode impedance while also maintaining a high differential mode impedance. This results in reduced noise levels and improved system performance.

The CM1011-105 is a versatile device and is used in a variety of applications. It is used to reject noise from AC mains, computer power supplies, automotive ignition systems, data communication systems, audio and video electronics, and even medical equipment. Its low-loss filtering capabilities also make it ideal for broadband applications such as satellite television systems, cell phones, and GPS systems.

In conclusion, the CM1011-105 is a critically designed CMC to reject common mode electromagnetic interference. It is a versatile device, providing very low common mode impedance, as well as high differential mode impedance for superior noise reduction. It is used in a variety of applications, including power supplies, motors, data communications, pulse, audio, and video electronics, and even medical equipment.
