6.1.2: Capacitance and Capacitors
Capacitors in Series and in Parallel. Multiple capacitors placed in series and/or parallel do not behave in the same manner as resistors. Placing capacitors in parallel increases overall plate area, and thus increases capacitance, as indicated by Equation ref{8.4}. Therefore capacitors in parallel add in value, behaving like resistors in series.

How to choose capacitor voltage rating for ESD protection?
The capacitors are supposed to absorb the charge from injected by the ESD event. If your ESD event would still give, for example 100 V across the capacitors (and you would use 150 V capacitors because of that) then **you would be missing the point of those capacitors providing ESD protection. That 100 V would already have damaged your IC!
Electric field in a parallel plate capacitor
A capacitor is a device used in electric and electronic circuits to store electrical energy as an electric potential difference (or an electric field) consists of two electrical conductors (called plates), typically plates, cylinder or sheets, separated by an insulating layer (a void or a dielectric material).A dielectric material is a material that does not allow current to flow and can ...
