Explaining Capacitors and the Different Types | DigiKey
So then, to make a capacitor with a larger value, one can use plates with a larger area, reduce the separation distance (i.e., thickness of the dielectric material) or increase the dielectric constant of the material. Messing with ε0 pretty much requires the creation of an alternate universe, which is a rather difficult thing to do outside the ...
capacitor
If the circuit needs less ripple, by far a better way to get it is to use a better regulator with more decibels of ripple rejection, rather than making the capacitor larger. A regulator that improves rejection from 85 dB to 110 dB will make the same difference as a really huge and impractical capacitor substitution.

electricity
This means that a capacitor with a larger capacitance can store more charge than a capacitor with smaller capacitance, for a fixed voltage across the capacitor leads. The voltage across a capacitor leads is very analogous to water pressure in a pipe, as higher voltage leads to a higher flow rate of electrons (electric current) in a wire for a …
Do you want your capacitor to have lower or higher tolerance?
Even in a very stable power source, larger smoothing capacitors would be better. Where you need a tight tolerance capacitor is in a tuned circuit. If you combine an inductor with a capacitor, you get a tuned circuit that resonates. The resonant frequency depends on the value of the capacitor and the inductor. The usual reason to construct a ...

Decoupling capacitors: what size and how many?
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 …
What are the consequences of using a capacitor that is of higher ...
The question should rather be "what made the capacitor have larger than rated capacitance". Electrolytic capacitors have a thin oxide layer as dielectric.
