Understanding Capacitor Voltage Ratings. 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 ...

The voltage rating on a capacitor is the maximum amount of voltage that a capacitor can safely be exposed to and can store. Remember that capacitors are storage devices. The main thing you need to know about capacitors is that they store X charge at X voltage; meaning, they hold a certain size charge (1µF, 100µF, 1000µF, etc.) at a certain voltage (10V, 25V, 50V, …
This means, if the actual circuit voltage is 10V, the minimum capacitor voltage I will select is 13.33V (10V/0.75). However, there is no such voltage. So, I will go to the next higher level that is 16V. Can you use 20V, 25V or even higher? The answer is yes. It depends to your budget because the higher the voltage, the expensive the capacitor ...

One of the principal factors affecting the capacitance of a capacitor is the type of dielectric material used between plates.

If a smaller rated voltage capacitor is substituted in place of a higher rated voltage capacitor, the increased voltage may damage the smaller capacitor.

High-K ceramic capacitors (X7R and the like) lose capacitance as the electric field increases. The electric field is the inverse of the distance between electrodes. Thus, a larger thicker cap (1206 vs 0603) will have thicker dielectric, a higher voltage rating, and capacitance will drop less with voltage. This also depends on value. In a 100nF ...

The working voltage of a capacitor depends on the type and thickness of the dielectric material employed. The DC working voltage is the maximum DC voltage and NOT the maximum AC voltage. A capacitor with a DC voltage rating of 100 volts DC cannot be safely used to an AC voltage of 100 volts. This is because an alternating voltage that has an ...

However, when an alternating current (AC) is applied to a capacitor, the change in voltage across the capacitor causes the capacitor to alternately charge and discharge at a rate determined by the AC frequency. This dynamic behavior introduces a resistance to the charge flow, which is dependent on the frequency and is known as capacitive reactance. …
