Common Mode Chokes is an electromechanical device used to constrain common mode signals. It is also a specialized kind of transformer that works on matched impedances to achieve maximum transfer efficiency of the desired signal, while also blocking the undesired signal. ICM0805ER371M is a kind of three line Common Mode Chokes. It offers superior Common Mode noise filtering for data line and peripheral circuit applications.

The ICM0805ER371M application field mainly involves data line and peripheral circuits. It effectively prevents EMI (electromagnetic interference) and crosstalk in Ethernet, PCMCIA card slots, and other data transmission interfaces. With its high signal integrity and reliable operation, it is ideal for connection interface applications. In addition, it is also applicable to the switching-mode power supply control line.

The working principle of the ICM0805ER371M is based on coils and ferrite beads. The coils are wound around a core made of the ferrite beads. This increases the inductivity of the coils, and hence adds to the impedance of the signal. The coils of the choke react with the common mode signals, and owing to the property of inductance, it impedes the passage of the undesired common mode signals, and hence blocks them from being transmitted. The coils are also designed to attenuate the common mode signals, in order to reduce the radiation of the signals and the amount of EMI.

In summary, the ICM0805ER371M belongs to the family of Common Mode Chokes, and can be used in a variety of applications such as data line and peripheral circuits, and even switching-mode power supply control line. Its working principle is based on the property of inductance, which impedes the passage of the undesired common mode signals, and hence blocks them from being transmitted. With its superior signal integrity and reliable operation, it is a reliable device for connection interface applications.
