Capacitor Specifications: what they mean
It is always good practice to run capacitors well within their rated voltage. There is a link between the margin provided between the actual voltage at which the capacitor is run and its rated operating voltage. The greater the margin, the higher the reliability. Often commercial design guidelines stipulate that capacitors should not be run above 50% of their …

How do I increase the voltage limit by connecting same capacitors?
If you have two 100V rated capacitors in series, you cannot assume that the combination of the two will be 200V. Slightly different leakage currents will mean one cap has more voltage across it than the other. This can be mitigated by adding resistors across each capacitor that have values lower than the effective leakage resistance of the capacitors. If the …
What does the Voltage Rating on a Capacitor Mean?
So if a capacitor is going to be exposed to 25 volts, to be on the safe side, it''s best to use a 50 volt-rated capacitor. Also, note that the voltage rating of a capacitor is also referred to at times as the working voltage or maximum working voltage (of the capacitor). So when seeing the (maximum) working voltage specification on a datasheet ...

For parallel capacitors, the analogous result is derived from Q = VC, the fact that the voltage drop across all capacitors connected in parallel (or any components in a parallel circuit) is the same, and the fact that the charge on the single equivalent capacitor will be the total charge of all of the individual capacitors in the parallel combination.
AC voltage ratings for capacitors
Lastly, any non-X/Y rated capacitor needs to be checked if it is capable of handling the expected current ripple. Some technologies to get higher capacity at high voltage cause high ESR in this type of capacitor, which makes them unsuitable for e.g. SMPS usage. I think this is all there is to it, let me know if I forgot something or borked up.
