Essentially, the improved ability of the material to sink charge without affecting the operation of the capacitor (until the breakdown of the dielectric) lends itself to optimization, a key factor considering the absolute number of capacitors a board may contain.
Just like a language, circuit design consists of repeating and indivisible characters that can be combined in endless orientations to create any response feasible within current technological constraints. Arguably, the most ubiquitous of these elements is the capacitor–a device most designers are familiar with after their first board.
Therefore, capacitors play the three following important roles in an electronic circuit. Capacitors can charge and discharge because of the structure. Featured by the electric charge and discharge, capacitors also can be used as a power supply. Camera flashes utilize this feature of capacitors.
However, the converted DC is an unstable current that includes ripples. A capacitor is used to remove these ripples and maintain a constant voltage. The flow of AC in a capacitor is useful for noise reduction. In general, since the noise in DC is an AC component with high frequency, it tends to go through the capacitor easily.
A larger capacitance means greater storage capacity, but slower rates of charge/discharge and vice versa. This leads to two important aspects of capacitor usage, the first being sizing decoupling capacitors based in part on the demands of the associated circuitry, and the second being their spacial placement.
