6 FAQs about [Capacitor breakdown value]

What is the breakdown voltage of a capacitor?

The dielectric is used in very thin layers and so absolute breakdown voltage of capacitors is limited. Typical ratings for capacitors used for general electronics applications range from a few volts to 1 kV.

What happens if a capacitor exceeds rated voltage?

What is the breakdown voltage of a dielectric capacitor?

For air dielectric capacitors the breakdown field strength is of the order 2–5 MV/m (or kV/mm); for mica the breakdown is 100–300 MV/m; for oil, 15–25 MV/m; it can be much less when other materials are used for the dielectric. The dielectric is used in very thin layers and so absolute breakdown voltage of capacitors is limited.

What determines the rated voltage of a capacitor?

The rated voltage depends on the material and thickness of the dielectric, the spacing between the plates, and design factors like insulation margins. Manufacturers determine the voltage rating through accelerated aging tests to ensure the capacitor will operate reliably below specified voltages and temperatures.

How do you calculate the maximum energy a capacitor can store?

The maximum energy (U) a capacitor can store can be calculated as a function of U d, the dielectric strength per distance, as well as capacitor’s voltage (V) at its breakdown limit (the maximum voltage before the dielectric ionizes and no longer operates as an insulator):

Can a voltage damage a capacitor?

When working with a capacitor, you will typically see two values printed on the side. The first is the capacitance, obviously, and the second is a voltage. This is the “breakdown voltage,” and it is the maximum voltage that the manufacturer guarantees will not damage the capacitor. You might ask yourself, “How can a voltage damage this capacitor?”
