Common Mode Chokes are components mainly used in the electronic industry, serving as a means of suppressing the effects of electromagnetic interference (EMI) on high-frequency electronic systems. The CM3822R201R-00 is a member of the Common Mode Choke family that has been designed to provide both high-frequency attenuation and low-frequency impedance characteristics, making it suitable for a range of applications.

Application Field

The CM3822R201R-00 can be applied in a variety of scenarios where EMI needs to be reduced. This includes automobiles or aircraft, where it can be used for bypassing noise on cables that connect various equipment, such as power supplies, sensors and other electronic parts. It is also suitable for industrial applications, including digital communications networks, or even wired and wireless consumer technology.

In addition, this specific model can be used in a wide variety of other applications due to its high-frequency characteristics. It has been designed for use as a data-line choke, capable of attenuating high-frequency noise from power and signal grounds, making it suitable for power-line communications and electromagnetic compatibility (EMC) tests.

Working Principle

Common Mode Chokes, including the CM3822R201R-00, work on the principle of induction. This means that they use an inductor to generate an electromagnetic field that is able to absorb and dissipate the electromagnetic interference created by other components or sources. This is done by creating a pulsed, high-energy field around the inductor, which absorbs the interference and dissipates it around the surrounding components.

The CM3822R201R-00 also utilizes a construction that includes two windings, a common mode and a differential mode, which helps it to filter out high-frequency noise and reduce the level of EMI. The two windings and the device’s overall design also help it to have a low DC resistance, which ensures that the choke does not add too much unwanted load to the circuit it is placed in.

Overall, the CM3822R201R-00 provides both high-frequency attenuation and low-frequency impedance characteristics, making it suitable for a range of applications. It can be used for power-line communications, EMC tests, and a variety of other applications that require noise suppression. With its two windings and unique construction, it is able to effectively filter out electromagnetic interference, making it a valuable component for any system.
