A Complete Guide to Capacitors
A ceramic capacitor is encapsulated with two leads that emanate from the bottom then form a disc. A ceramic disc capacitor does not have a polarity and connects in any direction on the printed circuit board. In ceramic capacitors, a relatively high capacitance is achievable in a small physical size because of its high dielectric constant.

A Complete Guide to Capacitors
The three-digit code printed on their body is used to identify the capacitor''s value in the picofarad. Letter codes are used to indicate their tolerance value such as the following: J = 5%, K = 10% or M = 20%. For example, the ceramic disc capacitor above with a ...
Capacitive Voltage Divider as an AC Voltage Divider
As the two capacitors are in series, the charge Q on them is the same, but the voltage across them will be different and related to their capacitance values, as V = Q/C. Voltage divider circuits may be constructed from reactive components just as easily as they
Inductors, Capacitors, Transformers Video Lecture
Transformers are used in nearly every electronic system that operates from AC power so they are widely used. Transformer operation is based on the same principle as inductors. Nearly every computer uses a transformer to step voltage down to …

What is the purpose of the capacitor in this transformer circuit?
The capacitor does the same thing but more so at higher frequencies. At too high common mode frequencies, the inevitable capacitive coupling in the transformer will cause some of the common mode signal on the input to show up as signal on the output.
