Dielectric strength
Instead, they have maximum voltage ratings. The breakdown strength of the dielectric will set an upper limit on how large of a voltage may be placed across a capacitor before it is damaged. Breakdown strength is measured in volts per unit distance, thus, the closer the plates, the less voltage the capacitor can withstand.

Capacitor Characteristics and Capacitor Specifications
cross-sectioned capacitors. Typically for low voltage capacitors the dielectric withstanding voltage test is carried out at 2.5 times the rated voltage. Based on parameters of the relevant distributions the probability of failure during this test, P. 2.5, can be calculated. For undamaged parts these probabilities were negligibly small
The voltage rating is the maximum voltage that a capacitor is meant to be exposed to and can store. Some say a good engineering practice is to choose a capacitor that has double the voltage rating than the power supply voltage you will use to charge it. ... this value refers to the maximum continouous voltage that a capacitor can withstand ...
Generally speaking, the capacitance and withstand voltage (rated voltage) of capacitors are in a trade-off relationship which is difficult to balance. In MLCC of the same size, when increasing the withstand voltage, the capacitance tends to decrease. Film capacitors possess a good balance of high withstand voltage and capacitance.
Instead, they have maximum voltage ratings. The breakdown strength of the dielectric will set an upper limit on how large of a voltage may be placed across a capacitor before it is damaged. Breakdown strength is measured in volts per unit distance, thus, the closer the plates, the less voltage the capacitor can withstand.

The maximum energy (U) a capacitor can store can be calculated as a function of U d, the dielectric strength per distance, as well as capacitor''s voltage (V) at …
If using a X2 rated safety box capacitor on a 240V AC line, will 275V voltage rating value be appropriate? I know that peak of the sine wave can reach 310V but can these ... 275VAC is a nominal rating; it means that you can use it on an AC supply that is (nominally) less than 275V RMS. The max voltage that it can actually withstand is …

Thus voltage rating of a capacitor is the maximum amount of voltage that can be applied across it to prevent it from being damaged permanently. Suppose, a capacitor having a voltage rating 10V then this means it can withstand at least 10V when applied across it. If higher voltage is applied across it then it can''t withstand which …
