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.
