name of the term: breakdown


Dielectric Breakdown: The selected dielectric material is designed to withstand the rated voltage and corresponding overvoltages under the rated operating conditions. Electrical or thermal overstress, as well as ageing or manufacturing flaws may cause the dielectric material to lose its strength and give way to an electric discharge (breakdown of the dielectric) between the capacitor plates. This discharge will initiate a self-healing process which insulates the faulty spot.
