Capacitors Explained

rf

In other words, any slightly imbalanced common-mode RF pick up is reduced differentially and both inputs to the transformer only receive a fraction of the differential RF noise that would be passed to the transformer output should the two capacitors be not present. That''s what the two 470 pF capacitors do. That much is clear.
