Common Mode Chokes (CMC) are a type of passive electronic device commonly used to prevent interference between two electrical circuits, commonly used on common mode signals, such as computer cables, Ethernet cables, and power supplies. The LF2823NP-223 is an example of a CMC that is commonly used in such applications.

The LF2823NP-223 is a high performance common mode choke offering good electrical characteristics and a small size suitable for most applications. It is made from ferrite material with a ferrite core, and consists of four discrete ceramic elements with a half-bridge construction. It has a 6.2 ohm inductance with a high self-resonance frequency of more than 200Mhz.

Common mode chokes, such as the LF2823NP-223, are often used for suppressing electromagnetic interference from external sources, such as other electronic components or the environment, and can be used in a variety of applications. In power supplies, they are used to reduce the level of noise that is generated by the AC mains or other sources. In computer networks, they are used to prevent the transmission of large amounts of data in a single packet, as well as to reduce the risk of data corruption from external sources. They can also be used in audio applications to minimize noise from the environment or from the audio output.

The working principle of a CMC involves its feature of high frequency self-resonance. A CMC, such as the LF2823NP-223, is able to prevent the transmission of high frequency signals between two circuits, effectively reducing the amount of interference and preventing any noise or data corruption. This is done by absorbing the high frequency signals, allowing only the desired frequencies to pass, and blocking out all other frequencies.

The LF2823NP-223 is a common mode choke that can be used in a wide range of applications, from power supplies, to computer networks, to audio applications. Using its high self-resonance frequency and high performance characteristics, it is able to effectively reduce the amount of interference from external sources, while retaining the desired frequencies. This makes it an ideal device for a variety of applications, and is a preferred choice among engineers and designers alike.
