0 GHz, the rating of the new filter is 2 GHz higher than that of the existing thin-film common mode filter for HDMI (TCM1210H-900-2P).
However, one pitfall of differential signaling is the tendency to ignore the accompanying common mode signal and mode conversion effects.
Common Mode noise, on the other hand, occurs between the hot or neutral wire and the ground wire causing logic confusion, data loss, system errors, blue screens or mysterious service calls that end without an actual problem being located.
Combining common mode inductors, interference suppression capacitors, and surge suppression devices in a small "hockey puck" package, these Compact EMI filters are available for 100 to 120V or 200 to 240V, and can be mounted with a single screw for use in multiple locations within a piece of equipment.
