This means, if the actual circuit voltage is 10V, the minimum capacitor voltage I will select is 13.33V (10V/0.75). However, there is no such voltage. So, I will go to the next higher level that is 16V. Can you use 20V, 25V or even higher? The answer is yes. It
why high voltage capacitors are used in low voltage circuits.
I''ve used One Hung Low high voltage capacitors (well tried them out as my boss didn''t want to pay for decent ones). Spec was 10nF, 4kV ceramics. Tested them with an LCR meter about 10nF (as near as makes no odds). Tested them with a higher voltage LCR ...

Electrolytic capacitor: Properties and operation
AC electrolysis is generally used for low voltage capacitors, and DC electrolysis is used for medium and high voltage capacitors. The multiplication factor is the ratio of the capacitance of the smooth surface to the etched surface and, usually, it reaches values ranging from 10 to 100.
How does a capacitor resist changes in voltage?
To see why it''s said that a capacitor ''resists'', or ''objects to'' changes in voltage at its terminals, it''s useful to compare its behaviour with a resistor (don''t confuse the ''resists'', meaning ''tries to stop'', with anything to do with the component ''resistor''). If …
voltage regulator
I work with low-power DC voltage regulators. I am already aware of the formula to calculate the size of smoothing capacitor(s). This can be an iterative process of testing one size with a scope and $begingroup$ This reason may be buried in one of the many good answers Some (only) regulators can be damaged by the output capacitor …
