Abstract
Abstract In an electrical capacitor with electrodes and an intermediate dielectric layer successively printed on a dielectric substrate, the improvement of so disposing the electrodes to minimize exposure of the dielectric layer to the atmosphere, and thus decrease the moisture sensitivity of the capacitor. Optionally, all exposed metallizations may be covered by a layer of solder.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
79 words
In an electrical capacitor comprising a dielectric substrate having a metallization thereon forming an electrode and connection means extending therefrom for connecting into electric circuits, a dielectric layer on the electrode, and a counterelectrode on the dielectric layer, the dielectric layer separating the electrode and counterelectrode; the improvement comprising said dielectric layer overlapping the peripheral edge of said electrode, and the counterelectrode overlapping the peripheral edge of said dielectric layer, for reducing the sensitivity of said capacitor to moisture.
