| 1. A capacitor assembly comprising:
a first solid electrolytic capacitor element;
a second solid electrolytic capacitor element positioned adjacent to the first solid electrolytic capacitor element, wherein
the first and second solid electrolytic capacitor elements each contain an anode formed from a valve metal composition having
a specific charge of about 70,000 μF*V/g or more, the anode having a thickness of from about 0.1 to about 4 millimeters;
a thermally conductive material positioned between the first and second solid electrolytic capacitor elements and electrically
connected thereto, wherein the thermally conductive material has a coefficient of thermal conductivity of about 100 W/m-K
or more at a temperature of 20° C.;
an anode termination to which first and second anode leads of the first and second solid electrolytic capacitor elements,
respectively, are electrically connected, wherein the anode termination contains a portion having an upper region and a lower
region, the upper region being electrically connected to the first anode lead and the lower region being electrically connected
to the second anode lead, the portion containing two or more arcuate surfaces between which an opening is defined;
a cathode termination to which cathodes of the first and second solid electrolytic capacitor elements are electrically connected;
and
a case that encapsulates the first and second solid electrolytic capacitor elements, wherein the case leaves exposed portions
of the anode and cathode terminations.
