Here’s a detailed overview of its construction, working, value selection and Applications: The construction of a coupling capacitor involves creating a device that can store electrical energy in an electric field and allow AC signals to pass while blocking DC components. Here’s a detailed look into the construction of coupling capacitors:
Whenever a capacitor is selected for coupling applications, there are some key parameters that need to consider like series resonant frequency, impedance, and equivalent series resistance. The value of the capacitance mainly depends on the frequency range of the application & the impedance of load or source.
Series Connection: Place the coupling capacitor in series with the signal path. The capacitor should be connected such that one end is connected to the output of the first stage and the other end to the input of the subsequent stage.
By far the simplest arrangement is to use a large value capacitor - one that is at least 10 times greater than theoretically needed. While it would be nice to have the luxury of using the same ratio for speaker coupling caps, this makes the capacitor overly large and expensive.
Coupling capacitors are mainly used in analog circuits whereas the decoupling capacitors are used in digital circuits. The connection of this capacitor can be done in series with the load for AC coupling. A capacitor blocks low-frequency signals like DC and allows high-frequency signals like AC.
On the other hand, if there is a sudden voltage spike, the capacitor stabilizes voltage by absorbing the excess energy. Apart from stabilizing voltage in electronic circuits, decoupling capacitors are also used to allow DC components to pass while shorting AC components to ground.

The critical contribution of coupling capacitors in amplifier sound
Over the years, with much experimenting and listening, I have found that a very major part of amplifier sound quality is directly due to the input coupling capacitors used. This is equally true for the output coupling capacitors of the preamp. Certainly the designer of the circuitry must do the job properly, but given that this is accomplished, and given that the amplifier has adequate …

The ceramic capacitor voltage dependence is striking. It is normal for X7R capacitor to have no more then 30% of rated capacity at rated voltage. For example - 10uF Murata capacitor GRM21BR61C106KE15 (0805 package, X5R) rated for 16V will give you only 2.3uF capacity with 12V DC applied at 25C temperature. Y5V is much worse in this respect.
