The dielectric withstanding voltage test (also called high-potential, over-potential voltage-breakdown, or dielectric-strength test) consists of the application of a voltage significantly higher than rated voltage for a specific time, between mutually insulated portions of a component part or between insulated portions and ground.
The ceramic forms the dielectric and serves as a carrier for the metallic electrodes. The minimum thickness of the dielectric layer, which today (2013) for low voltage capacitors is in the size range of 0.5 micrometers is limited downwards by the grain size of the ceramic powder.
