The invention relates to a variable capacitor which, due to its particular arrangement of electrodes, enables a significantly higher current flow than generally known constructions having the same or a similar structural shape, said capacitor also has an increased life expectancy and is compatible with existing capacitors in terms of connection. Such variable capacitors can be used in high frequency generators, in matchboxes and in interface networks for industrial high frequency applications, as regulatable filters in high frequency power electronics and in the power part of emission installations.

Variable capacitor having an increased current capacity

The invention relates to a bellows in a vacuum capacitor, whose bellows structure ( ) comprises a carrier material ( ) and at least one electrically conductive layer ( ), whereby the latter has a uniform thickness over the entire bellows structure. The deviations of the layer thickness from the mean are less than &plusmn;50% and preferably less than &plusmn;10%. This results in an increased life span with mechanical loading. In order to increase the heat emission through radiation, the bellows structure ( ) has an additional dark layer ( ). The used method provides for the application of the electrically conductive layers prior to the shaping process, which results in homogeneous layer thicknesses.
