Common mode inductor is essentially a two-way filter: on the one hand to remove common mode line electromagnetic interference signal, the other is to suppress itself does not emit electromagnetic interference, to avoid affecting the normal operation under the same electromagnetic environment of other electronic devices .
(1) the coil wire wound on should be insulated from each other to ensure that the transient voltage between the turns of the coil under the action of short-circuit breakdown does not occur;
(2) When an instantaneous large current flows through the coil, the core not saturated;
(3) Coil winding should be insulated with core to prevent transient voltage breakdown occurs under the action between the two;
(4) Coil should be wound as a single layer, this can reduce the parasitic capacitance of the coil, the coil for enhanced transient over-voltage tolerance.

Under normal circumstances, taking care to select the desired frequency band filter, common mode impedance the bigger the better, so we need to see the device selection information when the common mode inductance, mainly based on impedance frequency curve selection. Also pay attention to consider the impact on the differential mode impedance signal, focusing on differential mode impedance, pay special attention to high-speed port selection.

The main use of any electronic devices EMI radiated noise suppression, PC USB interface cable for PC and peripheral, 1394 lines, DVC, set-top boxes, LCD panels, low-voltage differential signaling (LVDS) in, noise suppression, high common-mode noise and low-band impedance differential mode impedance signal band.
