One is that the maximum rated voltage of a parallel connection of capacitors is only as high as the lowest voltage rating of all the capacitors used in the system. Thus, if several capacitors rated at 500V are connected in parallel to a capacitor rated at 100V, the maximum voltage rating of the complete system is only 100V, since the same voltage is applied to all capacitors in the parallel

6 FAQs about [Maximum load of voltage regulation of parallel capacitors]
What if two capacitors are connected in parallel?
(Thanks Neil for pointing this out) When 2 capacitors are connected in parallel, the voltage rating will be the lower of the 2 values. e.g. a 10 V and a 16 V rated capacitor in parallel will have a maximum voltage rating of 10 Volts, as the voltage is the same across both capacitors, and you must not exceed the rating of either capacitors.
What is total capacitance of a parallel circuit?
When 4, 5, 6 or even more capacitors are connected together the total capacitance of the circuit CT would still be the sum of all the individual capacitors added together and as we know now, the total capacitance of a parallel circuit is always greater than the highest value capacitor.
How many MLCC capacitors are required to meet the ripple voltage specification?
Three such capacitors in parallel are therefore required to meet the ripple voltage specification. The equivalent series resistance (ESR) of each MLCC is approximately 3 mW within the frequency range of interest and hence represents a negligible contribution to output ripple.
