ABSTRACT:
Disclosed is a metal-ceramic substrate made up of at least one ceramic layer which is provided with metallizations on both faces. In order to obtain a partial discharge resistance of less than 10 pC at a predefined measuring voltage, the thickness of the ceramic layer amounts to about one sixth of the measuring voltage.
