Common-mode suppression chokes are
mainly used to filter noise on AC power lines.
Noise on commercial power lines could enter
the equipment and disturb the proper
function. Noise generated by the equipment
for example from switch mode power
supplies need to be filtered and the spread of
such generated noise need to be suppressed.
Common-mode suppression chokes together
with line bypass capacitors building an AC
EMI suppression filter device.
