Abstract
The invention is directed to a low-capacitance multi-layer varistor having a ceramic body and two terminals that are applied on the ceramic body spaced from one another. The ceramic body is constructed in film technology with multi-layer structure and preferably comprises inner electrodes whose ends lie opposite one another with a gap.
Claims5
A multi-layer varistor, comprising:
- a ceramic body that is constructed in film technology;
- two terminals that are applied on the ceramic body at a specified distance from one another;
- inner electrodes that proceed comb-like from the two terminals, so that ends of the inner electrodes lie opposite one another with a spacing in a direction between the two terminals, the inner electrodes proceeding from one terminal do not overlap inner electrodes proceeding from the other terminal, at least one electrode of the inner electrodes in a layer being repeatedly interrupted so that only those parts of the at least one electrode that are adjacent to the terminals are connected to the terminals, and at least one other part of the at least one electrode is electrically separated from these terminals, the at least one electrode comprising a plurality of gaps in a serial arrangement.
