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). So when seeing the (maximum) working voltage specification on a datasheet, this value refers to the maximum continouous voltage that a capacitor can withstand without becoming damaged.

One important point to remember about capacitors that are connected together in a series configuration.

A 33 pF capacitor at 850 MHz has an impedance of about 6 ohms. If it is passing a power of 33 dBm (about 2 watts) to a 50 ohm load, the voltage seen across the 50 ohm is $sqrt{2times 50}$ = 10 volts RMS. The 50 ohm current will be 200 mA RMS and this will drop a peak voltage of about 1.7 volts across the series 33 pF capacitor.
When you increase the voltage above the breakdown voltage. The current will increase. Depending on the type of the capacitor it may lead to its destruction (and I wouldn''t dare to use this capacitor later on). Please note, that so found breakdown voltage may vary significantly for different capacitors from the same batch.

I am reading a datasheet from Murata for a ceramic capacitor. According to the datasheet: When AC voltage or pulse voltage is applied, the peak-to-peak voltage shall not exceed the rated DC voltage. I have googled a little and could not find any ceramic capacitor datasheet with surge characteristics.
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 ...

Therefore, if we use dc test voltage, we ensure that the dc test voltage is under root 2 (or 1.414) times the ac test voltage, so the value of the dc voltage is equal to the ac voltage peaks. For example, for a 1500-V-ac voltage, the equivalent dc voltage to produce the same amount of stress on the insulation would be 1500 x 1.414 or 2121 V dc.
