The capacitance of mica and ceramic capacitors is low (generally below 5000pF); the capacitance of paper and plastic capacitors is between 10 μ F to 5000 μ F; usually, electrolytic capacitors have a larger capacitance. Figure 2. 5000PF Ceramic Capacitor (2) Rated Voltage. T he rated voltage is another important parameter.
Voltage. A capacitor will have a marked voltage indicating its acceptable peak voltage, not its operational voltage. Therefore, you can select a capacitor with a voltage rating at or above the original capacitor. If you''re using a 370 volt capacitor, a 370 or 440 volt one will work, though the 440 volt unit will actually last longer.
10% of rated voltage to a maximum of 1 V at 25 °C, 3% of rated voltage to a maximum of 0.5 V at 85 °C, 1% of rated voltage to a maximum of 0.1 V at 125 °C. These guidelines apply for short excursion and should never be used to determine the maximum reverse voltage under which a capacitor can be used permanently. [46] [47]

Because of the stricter safety ratings, it is acceptable to use Y-rated capacitors in place of X-rated capacitors, but not vise versa. Capacitors explicitly rated for both are not uncommon, and there is nothing preventing a capacitor from being both classes at once. There are 4 subclasses of Y capacitors, Y1, Y2, Y3, and Y4. Here are …
A capacitor''s voltage rating is an indication of the maximum voltage that should be applied to the device. The context of the rating is significant; in some instances it may indicate a maximum safe …

The capacitor is manufactured by using electrical grade double side hazy biaxially oriented PP film interleaved with soft annealed high purity aluminum foil as its electrode.
Since the test voltage of the film capacitor is generally 1.7 times the rated voltage, and the dielectric strength is higher than the test voltage, it is generally not a problem to use a film capacitor with a rated voltage of 400V as a 630V film capacitor, unless the capacitor''s dielectric strength is tested before application.

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.

It is also normal to increase a voltage rating to avoid the very low voltage values sometimes seen, as capacitors with these low voltage ratings e.g. 6.3V are somewhat unreliable so an increase to 16V or 25V rated component could be beneficial. Note this is personal choice - not a forced action, and only applies to those low voltage …
