SMD Power Inductor smd emi suppression ferrite bead
Description:
The common mode inductor (Common mode Choke), also known as the
common mode choke, is a symmetrical coil that turns the same
direction in the closed loop. The ideal common mode choke has an
inhibitory effect on the common mode interference between L (or N)
and E, but the differential mode interference between L and N has
no inductance suppression. However, the incomplete symmetry of the
actual winding will lead to differential mode leakage inductance.
The signal current or power supply current is reversed in the two
windings, and the magnetic flux produced is offset by each other.
The choke has low impedance. The common mode noise current
(including the interference current caused by the ground loop, also
called the longitudinal current) is the same direction in the
direction of the two windings. The flux generated by the same
direction is added to the same direction, and the choke ring
presents a high impedance, thus suppressing the common mode noise.
