Capacitors have a maximum voltage, called the working voltage or rated voltage, which specifies the maximum potential difference that can be applied safely across the terminals. Exceeding the rated voltage causes the dielectric material between the capacitor plates to break down, resulting in permanent damage to the capacitor.
One very important rating of capacitors is "working voltage". This is the maximum voltage at which the capacitor operates without leaking excessively or arcing through. This working voltage is expressed in terms of DC but the AC equivalent is about only one half of that DC rating.
So if a capacitor is going to be exposed to 25 volts, to be on the safe side, it's best to use a 50 volt-rated capacitor. 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).
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.
Generally the capacitance value which is printed on the body of a capacitor is measured with the reference of temperature 250C and also the TC of a capacitor which is mentioned in the datasheet must be considered for the applications which are operated below or above this temperature.
A capacitor may have a 50-volt rating but it will not charge up to 50 volts unless it is fed 50 volts from a DC power source. The voltage rating is only the maximum voltage that a capacitor should be exposed to, not the voltage that the capacitor will charge up to.

Polarized vs. Non-Polarized Capacitor: What''s the Difference?
How can you identify if a capacitor is polarized or non-polar? The simplest way to identify if a capacitor is polarized or non-polarized is by its physical shape. Polarized capacitors often have a stripe down one side, which is the negative terminal, and the other end of the capacitor will be positive. Non-polarized capacitors are generally ...

Capacitor Codes: Capacitor Markings and Tolerance Code Chart
For larger capacitors, two main parameters are displayed: capacitance and breakdown voltage. Capacitance is usually indicated in microfarads (μF). For instance, "150μF" clearly denotes 150 microfarads. Alternatively, a three-digit code might be used, like "224," which translates to 220,000 picofarads (pF). This is calculated from 22 x 10^4.

How to Replace a Capacitor: The Comprehensive Guide to Capacitor …
When a voltage is applied across a capacitor, it accumulates an electric charge on its plates. This charge creates an electric field between the plates, with the insulating dielectric material between them preventing the flow of current. The amount of charge a capacitor can store, known as capacitance, is determined by factors such as the surface area of the plates …
