Limiting the withstand voltage of capacitors [PDF]

6 FAQs about [Limiting the withstand voltage of capacitors]

What happens if a capacitor exceeds rated voltage?

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.

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.

What is the maximum rated voltage for a capacitor?

The maximum rated voltage for the component should be at least double the capacitor maximum voltage that can be applied to the component in normal operations. A more accurate calculation can come from looking at the relationship between the breakdown voltage and the maximum rated voltage.

How can capacitor maximum voltage be reduced?

This issue can be resolved by ensuring that the capacitor maximum voltage calculated from the peak signal voltage and DC bias voltage remain within the region of the component’s capacitance characteristics, where the change in capacitance is minimal.

What happens if a capacitor fails?

In the worst-case scenario, the capacitor could fail catastrophically, leading to safety hazards or permanent damage to the system. Always ensure the capacitor voltage matches or exceeds the expected working voltage of the application to avoid such risks. Is it okay to use a capacitor with a higher voltage rating than required?
