Capacitor Voltage: What Is It and How Does It Works?
Capacitor voltage is crucial in electrical circuits. The plates are usually made of metal, such as aluminum. The dielectric, which can be made of materials like ceramic, mica, or plastic, is an insulator that prevents the direct flow of current between the plates. A larger capacitance can better smooth the voltage, but the working

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.

How to choose voltage value of capacitors
As the electrolytic''s working voltage rises, so does the ESR, assuming that the capacitance is the same. So, for a 5V application, a 1uF/700V capacitor performs much worse than a 1uF/16V capacitor. The downside of higher rated capacitors is usually their increased physical size which takes away board space and adds inductance. So - besides

6 FAQs about [The voltage of the capacitor when it is working normally]
What is a capacitor's working voltage?
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.
Do capacitors have same capacitance?
Even though capacitors have same capacitance value they may have different working voltages. If you use a capacitor which has low working voltage in place of a capacitor which has high working voltage then the increased voltage may damage the low voltage capacitor even though both capacitors have same capacitance.
Should a capacitor be rated 50 volts?
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).
Can a capacitor charge up to 50 volts?
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.
Can a capacitor be damaged if a DC or AC voltage is higher?
If you apply a DC or AC voltage which is greater than the working voltage of a capacitor then the capacitor may damage. The working voltages which are commonly printed on the body of a capacitor are 10V, 16V,25V, 35V, 50V, 63V, 100V, 160V, 250V, 400V and also 1000V.
Are DC & AC voltage values the same for a capacitor?
DC and AC voltage values are usually not the same for a capacitor as the AC voltage value refers to the r.m.s. value and NOT the maximum or peak value which is 1.414 times greater. Also, the specified DC working voltage is valid within a certain temperature range, normally -30°C to +70°C.
