Abstract

The present invention provides a new type of thin-film capacitor which is insensitive to breakdown voltages during its mounting on a printed circuit board. Said capacitor has an insulating substrate having at least two internal electrode layers which are mutually separated by means of a dielectric layer. The substrate also has two end contacts each of which are electroconductively connected to one of said internal electrode layers. According to the invention, the capacitor also has breakable electrically conductive means, preferably formed as a metal layer, which means are electrically connected to said end contacts. The presence of said breakable electrically conductive means between said end contacts prevents damage due to electrical storage which can arise during the mounting of the capacitor on a printed circuit board.
