6 FAQs about [Capacitor terminal voltage considerations]

What are the limitations of a capacitor?

Capacitors, like all electrical components, have limitations that must be respected for the sake of reliability and proper circuit operation. Working voltage: Since capacitors are nothing more than two conductors separated by an insulator (the dielectric), you must pay attention to the maximum voltage allowed across it.

What happens if you put too much voltage on a capacitor?

Working voltage: Since capacitors are nothing more than two conductors separated by an insulator (the dielectric), you must pay attention to the maximum voltage allowed across it. If too much voltage is applied, the “breakdown” rating of the dielectric material may be exceeded, resulting in the capacitor internally short-circuiting.
