Abstract

A capacitor assembly with a substrate having a first face and a second face. A multiplicity of capacitors are mounted on the first face wherein each capacitor has a first lead and a second lead of opposite polarity to the first lead. A bridge is in electrical contact with multiple first leads. A tree is in electrical contact with the bridge wherein the tree passes through a via of the substrate and is in electrical contact with a first trace of the second face. A second trace is on the second face wherein the second lead is in electrical contact with the second trace.
