Electrical characteristics:

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.
