Common Mode Chokes, commonly known as CM chokes, offer high impedance to the common mode current while maintaining low impedance to differential mode currents in two-wire systems. The CM choke also helps minimize the effect of electromagnetic interference (EMI) that emanates from an inductive load or other sources.

The UF2327S4-442Y1R3-01 common mode choke from Knowles Coilcraft is a shielded, snap-on type inductor designed to suppress common-mode noise in two-wire systems. It features a broad operating frequency range of 10-500MHz, a high inductance value up to 30uH, a high current rating of 1.5A, and high quality shielded construction.

The primary application field for the UF2327S4-442Y1R3-01 is in the industrial and instrumentation markets for electronic functions, such as clocks, robotic systems, and industrial control applications. Its use in these areas is due to its efficient noise suppression, effective filtering of common-mode currents, reliable performance, and low distortion figures.

The UF2327S4-442Y1R3-01 also finds use in the communication industry. It is often used in automotive brake systems, navigation systems, and communication systems such as the CDMA and GPRS networks, where it provides reliable and efficient commonmode noise suppression.

The working principle of a CM choke is based on the principle of electromagnetic induction. The inductor, through a flux-coupled electric field, induces an electric current in two conductor wires in the form of a current proportional to the flow of electric charge. This current induces an opposing voltage in the semiconductor material of the wire, which effectively reduces the amount of current flowing through the wire.

By utilizing this concept, the CM choke is able to suppress common-mode noise in two-wire systems. The CM choke induces a voltage that is opposite to the applied voltage across the two conductors, effectively reducing the flow of current between them. As a result, the common-mode noise is cancelled out, making it difficult for the noise to reach the other system portions.

The UF2327S4-442Y1R3-01 provides efficient and reliable noise suppression for a wide range of applications. Its high inductance, high current rating, and low distortion figure aid in providing superior performance and stability even in the presence of high levels of interference and common-mode noise.
