Difference between capacitors of same value but different sizes

If you want the capacitor to handle more current or have lower ESR then the thickness of the metal layers needs to be increased. The breakdown voltage of a dielectric layer is proportional to the thickness of the layer. Therefore making thicker layers may create capacitors with larger voltage ratings.

What does the Voltage Rating on a Capacitor Mean?

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

The Different Capacitor Types: Symbols and Applications

The capacity depends on the size of the capacitor and the dielectric. The higher it is, the larger the plates with more surface area and a higher relative permittivity. This is usually measured in Farads (F), where one Farad equals 1 Coulomb per Voltage (1F 1C/V). Capacitors also vary on the following: Maximum operating temperature; Leakage current

6 FAQs about [The capacity of low voltage capacitors is different]

What happens if capacitance does not vary with voltage?

If capacitance doesn't vary with voltage, the amount of charge that can be held is proportional to the product of capacitance and the voltage limit. If capacitance does vary with voltage (a situation equivalent to a tank of non-uniform cross section) the charge is proportional to the integral of the capacitance over voltage.

Why is a high voltage capacitor not a capacitor?

Operating a high voltage capacitor at lower dc voltage cause some low continuous current to flow through the capacitor, thus rendering the capacitor not behaving ideally as a capacitor. The voltage rating of the capacitor is the point at which the dielectric & insulation between the two plates starts to break down and fails.

Are MLCC capacitors rated at low voltage?

You tend to find more like the opposite. A high voltage capacitor will have it's capacitance rated at low voltage meaning when operated close to it's rated voltage the capacitance will be much lower. This is why the different MLCC capacitor dielectric types exist, they guarantee a certain capacitance vs voltage characteristic (amongst other things)

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.

How much voltage does a capacitor hold?

While not a perfect analogy, think of the voltage on the capacitor similar to the liter capacity of a tank. It will hold "35 V" but you needn't fill it completely.
