<p>A capacitor assembly comprising a first 22 and second 24 solid electrolytic capacitor elements electrically connected to common anode 67 and cathode terminations 72; the capacitor elements contain an anode 6a,6b, a dielectric coating overlying the anode that is formed by anodic oxidation, and a conductive polymer solid electrolyte overlying the dielectric layer; the capacitor elements are spaced apart from each other a certain distance such that a resinous material substantially fills the space between the elements. A method of forming the capacitor assembly is also disclosed, wherein the anodes of the capacitor elements are formed from a valve metal or a conductive oxide thereof. The capacitors may be spaced apart by between 40 and 100 microns. The resinous material may also be epoxy resin. The resinous material can limit the expansion of the conductive polymer layer to such an extent that it does not substantially delaminate from the capacitor element. In addition to possessing mechanical stability, the capacitor assembly also possesses a combination of good electrical properties, such as low ESR, high capacitance, and a high dielectric breakdown voltage.</p> |
