Decoupling and Filtering Capacitors Guideline
With decoupling capacitors, the different stages in the circuit do not have to wait to receive the power that they need because there is an extra supply held by the capacitor. Ideal circuit design is one the uses small value capacitors to handle short-term, fast transients and larger value capacitors for slower transients.

Guitar amps use several large filter capacitors to get this power-conditioning job done properly. Even smaller amps tend to use at least three, arrayed side-by-side in stages to filter the supply at points where the DC is passed along to the output transformer, the output tubes, and the preamp tubes, respectively.

6.1.2: Capacitance and Capacitors
Modest surface mount capacitors can be quite small while the power supply filter capacitors commonly used in consumer electronics devices such as an audio amplifier can be considerably larger than a D cell battery. A sampling of capacitors is shown in Figure 8.2.4 . Figure 8.2.4 : A variety of capacitor styles and packages.
How do smaller capacitors filter out higher frequencies than larger ...
Whilst the average power consumption is low, the dynamic (i.e., peak) consumption is high. The bypass capacitor provides the local source for these peak currents. As current flows in a loop, to minimise the effect of the inductance of the power supply wiring, the decoupling capacitor should be placed as close as practicable to the IC.

Another common filter is placing two capacitors in parallel with a series inductor between these. This is used for circuits with larger loads. The first capacitor smooths the ripple. The inductor opposes the change in current and tries to keep it constant and the second capacitor, which is much smaller, will then smooth out the final …

power supply
A large capacitor like the 2200 uF act as a "reservoir" to store energy from the rough DC out of the bridge rectifier. The larger the capacitor the less ripple and the more constant the DC. When large current peaks are drawn the capacitor supplied surge energy helps the regulator not sag in output.
Why the Capacitor in Your Power Supply Filter is Too Big
Typically a large filter capacitor is used to absorb and store energy when the AC power is higher than what is needed by the DC load and to supply energy to the load when the AC power is lower than …
