Introduction of EMC ProductsIntroduction of EMC Products--BeadsBeads
SHENZHEN SUNLORD ELECTRONICS CO., LTD
How Ferrite Beads Work ?Bead is a frequency dependent resistor. At low frequencies, inductive impedance is low.At higher frequencies, the impedance increases and
becomes resistive function .The resistive loss attenuates the unwanted frequencies
through heat dissipating of the bead’s ferrite material due to eddy currents.

Common-Mode and Differential Mode Signal
Common-Mode Signals: Two signals on a pair of signal lines have the same amplitude and the same direction. Common-mode signals may also appear on single-ended signal lines and ground lines.
Differential Mode Signals: Two signals on a pair of (differential) signal lines, have the same amplitude and the opposite direction.
Common-mode signals are almost always harmful, such as the common-mode noise coupled from differential signal lines. So many design rules are designed to prevent the emergence of common-modesignals. Differential mode signals generally appear in the differential circuit, and as the data transmission carrier, it is necessary to be retained. So in circuit designing, it is needed to keep the Differential mode signal as much as possible.

The magnetic flux arose from differential mode current subtract each other and has a smaller resistance.
Equivalent Circuit
Characteristic: For common-mode noise, work as beads; for differential mode signal, work as short lines.
The magnetic flux arose from common mode current adds each other and has a greater resistance.
SHENZHEN SUNLORD ELECTRONICS CO., LTD
Impedance reducing caused by magnetic saturation will not easily appear even by a large current.
Common mode choke is suitable for noise suppression in high current circuits, such as power supply lines of AC/DC.
Less Waveform distortion
Common mode choke is suitable for the circuits which are sensitive to waveform distortion, such as video signal lines.
