Common mode choke coils (CMCC) are filters that reduce common mode noise that is problematic in differential transmission lines (non-automotive use: USB, HDMI, Mipi, etc.; automotive use: CAN, CAN-FD, 100Base-T1, 1000Base-T1, SerDes, A 2 B ®, etc.), power lines, and audio lines. They are ideal for suppressing common mode noise with frequencies ranging from …

Common Mode Choke A common mode choke has 2 windings on the same core. Imagine a single inductor on the AC high side with a phasing dot on the left of the coil. Now, place an exact inductor on the neutral line of the AC input with the phasing dot to the left of the coil. Now imagine these 2 coils on the same core and you have a common mode choke.

a common mode choke can be modeled simply as 2 mutually coupled inductors each of inductance say L. When they are wired with the correct polarity, the mutual inductance will "cancel out" the total of each self inductance ( M = 2*L), thus for differential currents total apparent inductance = 0, and for common mode currents total apparent inductance = 2 * L.

the common mode signal that enters or leaves a PCB. X and Y capacitors are commonly used to shunt the common mode noise away from the circuits of interest, while a common mode choke is used to attenuate or dampen the noise. When placing an inductive component such as a choke in the path of current, there are a few key items one must consider.

often tell you to either install a Common Mode Choke or vary the length of your coax until you get a decent SWR match. You can also sometimes see this effect when using an external (to your radio) SWR bridge. SWR should be the same along the entire feed line. If the external meter shows one SWR and your radio’s built in meter shows another then

Common mode chokes, or common mode inductors, consist of two or more coils of insulated wire on a single magnetic core. Each winding is put in series with one of the conductors. This means that the magnetic fields of the wires combine to present high impedance to the noise signal.
