Abstract
A multi-capacitor module carries vertically-oriented surface mount tantalum capacitors. The module provides at least one conductor for coupling to the substrate capacitor terminals that are distal thereto. The module occupies less space, when mounted to a circuit board substrate, than individually mounting the bases of the surface mount capacitors to the substrate. This allows more efficient use of volume within an implantable cardiac rhythm management device, reducing its size, or alternatively, increasing its implanted longevity.
