How to choose capacitor voltage rating for ESD protection?
$color{red}{boxed{^1}}$ 195 volts is a little high due to the liberty I took when reducing the 50 MΩ resistor to 100 kΩ. I took this liberty to speed up the 150 pF charge time so that the sim result was more easily viewable. In reality, with basic charge redistribution from the 150 pF capacitor to the 10 nF capacitor, the peak voltage would be: -

What Size Capacitor Should I Use?
Usually, capacitors are derated by the following rule of thumb: a capacitor is selected such that its voltage rating is two to three times greater than the expected operating voltage. Derating increases the footprint requirements of the capacitor because, with an increase in working voltage, the physical size of the capacitor also increases.
analog
With this in mind, capacitor selection is still important, and one must be mindful of capacitance degradation due to the bias voltage when using ceramic caps for this purpose (although you are correct that they shouldn''t be making much noise because the signal voltage should be low) $endgroup$ –

Choosing capacitor voltage rating for a Marx generator
A Marx generator charges capacitors in parallel then discharges them in series. I read that the voltage across each capacitor accumulates when they are connected in series, which causes subsequent spark gaps to break down after the initial gap is triggered.
Capacitor Specifications: what they mean
A capacitor with an appropriate ripple current and working voltage rating should be chosen. Polarity and Reverse Voltage – If an electrolyte capacitor is used in the circuit, it must be connected in the correct direction. Its reverse voltage rating should be at least twice the possible reverse voltage in that branch of the circuit.
voltage
I recommend using a ceramic capacitor, depending on application you can generally use a ceramic capacitor 1/3rd to 1/10th the required electrolytic value. Or a relatively high ESR tantalum. You generally want LOW ESR input capacitors and most of the time the output can also be LOW ESR.
Choosing the Right Capacitor for Your Circuit
A general guideline is to select the capacitor with a voltage rating of 20-50% greater than the maximum voltage. However, choosing capacitors with higher voltage ratings can increase costs, depending on budget constraints. Additionally, the physical size requirements of the capacitor should also be taken into consideration when making a choice.
