Common Mode Chokes (CMCs) are devices used to prevent unwanted signals passing through a signal path. They are typically used to reduce the undesired transfer of signals from one electrical device to another due to cross-talk, ground loops or interference from other devices. The SU9VD-07020 is one such Common Mode Choke used in the signal path.

The SU9VD-07020 is a surface-mount Common Mode Choke. It is an inductor used to suppress EMI noise, consisting of a ferrite core and compact internal winding. It has a low insertion loss from 500 MHz to 2.4 GHz and its high performance makes it suitable for high-frequency signal lines with data rates up to 10 Gbps. The device can be used in differential lines of data cables, power feeds, and board-to-board connections.

The design of the SU9VD-07020 Common Mode Choke reduces crosstalk and noise in the signal path. This prevents interference from other electric and electronic components. The choke is designed in an SMD package, which provides superior noise reduction capabilities compared to other traditional inductors. Its low profile makes it ideal for space constrained areas.

The working principle of the SU9VD-07020 Common Mode Choke is based on Faraday’s Law of induction. In this case, the common-mode signal or noise is induced by a loop antenna created by the electric device. The choke drives the induced current through the winding thus reducing the unwanted noise due to its high impedance.

The SU9VD-07020 Common Mode Choke is suitable for use in many applications, including consumer electronics, RF & communication devices, data storage, power converters, and automotive. It can also be used in high speed signal transmission circuits, such as USB3.1, HDMI 2.1, SAS 3.0, and PCIe. The device helps reduce the common-mode noise efficiently without introducing a voltage difference on the differential pair.

The unique design of the SU9VD-07020 provides excellent performance that is suitable for high-frequency applications. It can effectively reduce common-mode noise and provide stable signal transmission, making it an ideal choice for suppressing interference in signal paths.
