Noise Management using Capacitors: Effectiveness of
As an example, the following table compares the ripple reduction effects when 20 units of 330 uF aluminum electrolytic capacitors or 10 units of tantalum electrolytic capacitors are replaced by one unit of SP-Cap. As you can see, a single SP-Cap achieves adequate ripple reduction effects, which can significantly reduce quantity, space, and costs.
Noise reduction capacitors on PCB
Well I don''t think you can buy one, but a 6V5 rated capacitor represents an 80% derating which is the recommended derating figure.

Of course the power supply is something different altogether.

Adding a capacitor to reduce the bass of a pickup?
The more reduction in bass that you want the bigger the pot value, but at some point it will be full one. I just don''t know what value trimmer will be big enough to give 100% reduction that the cap is capable of. I would say 100k should be plenty tho. If not, try 250k. they''re pennies apiece so just get a few values and experiment.

Capacitors and Calculus | Capacitors | Electronics Textbook
Capacitors do not have a stable "resistance" as conductors do. However, there is a definite mathematical relationship between voltage and current for a capacitor, as follows:. The lower-case letter "i" symbolizes instantaneous current, which means the amount of current at a specific point in time. This stands in contrast to constant current or average current (capital letter "I ...
