Re: capacitor comparison I think a big capacitor does not give any advantage, however, smaller cap in parallel does give some: 1. Smaller cap, you may not need to specifically reserve a big area for the capacitor. It can be squeezed into some empty spaces, hence giving area saving. 2. Smaller cap, earsier to match if is required. 3.

Big capacitors are intended to offer low impedance at low frequencies and small capacitors (higher resonant frequencies) are intended to offer low impedance in high frequencies. In Figure 2 you can see the theoretical idea using 4 capacitors (100uF, 10uF, 100nF, and 100pF).
The capacitors combine in parallel, so 10 + 220 equals 230 microfarads. We can keep adding more such as a 100 microfarad capacitor. And the total is just the sum of all of the capacitors.

It have found that the notch filter have more effect with two capacitors of 33 uF in parallel instead of one big capacitor of +/- 66uF. So I think I''m going to build this filter with 2 capacitors of 33uF instead of on big capacitor.
This is where the multiple values of capacitors come into play. The capacitors have some small parasitic inductance, also. Each capacitor you add creates an LC filter. Each different capacitor value, combined with the parasitic inductance, filters a different range of frequencies. It is common to see a 100pF next to a 0.1uF cap at each power pin.
It''s common to use the small ones to filter out high-frequency noises. It is all because the capacitors are not ideal. An ideal big capacitor must filter any noise bigger than the cut-off frequency of the circuit. The higher the frequency, the better filtration. However, the big capacitor does not work well at higher frequencies in the real world.
