Take note that a capacitor''s voltage rating is not the voltage that the capacitor will charge up to, but only the maximum amount of voltage that a capacitor should be exposed to and can store safely. For the capacitor …
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. If one capacitor is low in value by 10% and one is high by 10% there will be 20% more voltage seen across the lower value capacitor hence, you can''t really assume a 200 volt pulse withstand ...

An example of this misconception is: Given an application for a capacitor of 50 nF at 10-kVdc working/operating voltage, a capacitor can be designed within the approximate dimensions of 3.5-in. × ...
Once the capacitor is charged in your circuit, no current will flow. If the capacitor is fully discharged, then the current at the start will be 100 V/8 Ω = 12.5 A, but since the power supply can only deliver 5 A you will only get 5 A during the charge phase. As the capacitor charges, the current flow will go to zero.

Mica capacitors can withstand high voltages, operate at high temperatures and have low leakage current. ... Their high voltage rating makes their application in RF power amplifier coupling and decoupling attractive despite their relatively high cost. Silver mica capacitors can have very large dv/dt ratings (e.g., 100, ...
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.
Breakdown strength is measured in volts per unit distance, thus, the closer the plates, the less voltage the capacitor can withstand. For example, halving the plate distance doubles the …

How do I increase the voltage limit by connecting same capacitors?
Connecting two identical capacitors in series, each with voltage threshold v and capacitance c, will result into a combined capacitance of 1/2 c and voltage threshold of 2 v.. However, it is far better to get a single capacitor that meets the higher voltage threshold on its own as combining capacitors in series will also lead to a higher Effective …
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 …

What happens if I connect a low voltage rated capacitor to a high voltage?
This might also be a simplification of the real life phenomenon of overvoltage breakdown. Chemical reactions might also occur which can change the capacitor''s behavior. So, if you want to make a small capacitor of a high capacitance, it will have to be limited to low voltages. High voltage, high capacitance ones are big for this reason.
