Common Mode Chokes, such as B82724J8432N040, are devices used in signal applications for filtering, noise suppression, and transient protection. It is designed to provide differential-mode noise and common-mode noise suppression with maximum power line disruption.

Operating Principle

Common Mode Chokes need an alternating current (AC) supply to create a magnetic field. The AC voltage is the signal that the choke attempts to reduce. This signal is contained in both the differential-mode and the common-mode components. The choke works to absorb energy contained in the common components of the signal, by creating an opposing electromagnetic field. This opposing field reduces the amplitude of the common component but has less effect on the differential component. As a result, the common mode noise signals are attenuated while higher-frequency differential mode signals remain unaffected.

Common Applications

Common Mode Chokes have a wide range of applications in signal-level power transmission applications. Such as they are widely used to limit Common Mode noise (CMN) and differential mode noise (DMN) generated in communication networks, power transmission lines, industrial equipment, medical equipment, audio/video equipment, household appliances, and electronic devices. Generally, common mode chokes are used to suppress the harmonic components caused by nonlinear loads, such as rectifiers, to reduce common-mode noise and to protect equipment against voltage transients.
