Abstract
An electrochemical capacitor chip device (10) includes a plurality of capacitor subassemblies (12, 14, 16, 18, 20, and 22) arranged in stacked configuration. Each stacked capacitor assembly shares a single common electrode (48) from which extends a contact tab. Attached to contact tabs are lead pins (26, 28, 30 and 32) for effecting electrical and mechanical communication with, for example, a printed circuit board. The capacitor subassemblies may be preferably fabricated of electrochemical capacitor subassemblies employing gelled polymeric electrolyte structures.
