High-voltage capacitor in a low-voltage system
The voltage rating of a capacitor is a measure of how strong its insulation is. A 35V cap can withstand at least 35 volts applied across it (a higher voltage may cause bad things like a short through the cap and burnup). It has nothing to do with how much voltage the capacitor will store; it can store nothing higher than is input to it.

6 FAQs about [400V low voltage capacitor withstand voltage]
Is 400 volt a good polarity capacitor?
It has no defined polarity like the electrolytic capacitors have. In this application only an unpolarized and high voltage capacitor is ok because it must stand the mains AC voltage. 400 V is quite a low safety margin selection for 230VAC except if it's stated in capacitor's datasheet that 400 V means "continuously stands 400VAC".
Can a capacitor charge up to 50 volts?
A capacitor may have a 50-volt rating but it will not charge up to 50 volts unless it is fed 50 volts from a DC power source. The voltage rating is only the maximum voltage that a capacitor should be exposed to, not the voltage that the capacitor will charge up to.
Is a 400 volt DC capacitor good for 230 volts?
@Chupacabras if your supply is 230 V AC then the peak voltage can be as high as 325 volts. Add (maybe) 20% for powergen issues and you get to 390 volts peak. A 400 V DC capacitor is OK but 450 V would be better and maybe, that is possibly why the 400 V DC capacitor failed. Feb 1, 2017 at 12:39 Your capacitor has plastic insulation layer.
How many volts can a series capacitor withstand?
This is because the 12.77 volt seen during the pulse (as previously derived in my answer here) is shared equally between two series capacitors. Given that the capacitors have a voltage rating of 100 volts, if they have the same value then the peak voltage withstand for two in series is 200 volts.
Should a capacitor be rated 50 volts?
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).
What is a 400V DC capacitor?
According to comments and answers, this capacitor is polyester (or polypropylene), with rating 400V DC. A capacitor is a capacitor, it doesn't care particularly about what kinds of signals go through it, as long as you stay within its SOA. PlasmaHH, there is some reason why some caps are rated 400VDC and some 400VAC, or 250VDC/250VAC. Isn't it?
