Common Mode Chokes (CMC) are electrical components used to suppress differential and common-mode noise in electrical circuits. Each type of CMC has its own application field and working principle, and CM1922X330R-00 is no exception. In this article we will explore the application field and working principle of CM1922X330R-00.

CM1922X330R-00 has been designed for use in Radio Frequency Identification (RFID) applications for the suppression of Radiated Immunity Tests. It is also suitable for the suppression of three- and four-wire Power Line, in which two of the wires are twisted together. This reduces the Common Mode Noise on the whole line, improving the EMC immunity of equipment connected to it. The product is also well suited to, installation in industrial control panels, providing EMC protection for those devices connected.

The CM1922X330R-00 is constructed wholly using ferrites, offering excellent suppression performance over the frequency band of 9 kHz to 1 GHz. The shape of the ferrite core gives it its own unique size and feature set, making it ideal for use in applications where space is limited. The product is also highly stable over temperature, making it ideal for use in external RFID and EMC immunity suppression.

The working principle of CM1922X330R-00 is that of common mode choke. It works by providing an low impedance path for common mode signals at the frequency of operation, while providing a high impedance path for differential mode signals. This ensures that only signals that match the frequency range of the choke pass through the choke, allowing the remaining signals to be suppressed. The result is an improved EMC immunity of the connected equipment.

To sum up, CM1922X330R-00 is a common mode choke designed for use in Radio Frequency Identification (RFID) applications for the suppression of Radiated Immunity Tests. It offers excellent suppression performance over the frequency band of 9 kHz to 1 GHz. It is also suitable for the suppression of three- and four-wire Power Lines, in which two of the wires are twisted together. The working principle of CM1922X330R-00 is that of common mode choke, which provides an low impedance path for common mode signals at the frequency of operation, while providing a high impedance path for differential mode signals.
