Variable capacitors can produce a range of capacitances, which makes them a good alternative to variable resistors in tuning circuits. Twisted wires or PCBs can create capacitance (sometimes undesired) because each …
Can I Replace a 16V Capacitor With an 25V Capacitor? [7 …
To make sure it can manage the voltage in the circuit, it''s crucial to select a replacement capacitor with a voltage rating that is at least as high as the original capacitor''s. In this situation, a 25V capacitor would be an appropriate replacement because it has a greater voltage rating than a 16V capacitor.

Can I replace a 0.1µF capacitor with 1µF in this circuit?
Yes, you can replace the 100 nF (in engineering you keep 1-3 digits left of the point and adjust the units multiplier accordingly) with a 1 µF, but only if it is low ESR (equivalent series resistance). The 100 nF you show …
Can I replace all electrolytic capacitors with ceramic?
Since applied voltage can change the dimensions of the capacitor, changing its dimensions by applying stress can change its open-circuit voltage. In effect, the capacitor acts as a microphone. It can pick up the mechanical vibrations the board is subjected to, and those can make their way into the electrical signals on the board.
