A capacitor (14) is disposed in, for example, a ferrite shell (12). A winding (20) is formed around the shell, thereby providing an inductive component. Additional windings may be provided to form a transformer. In combining the two components into a unitary package, a space savings is realized, and assembly efficiency is increased.

Unitary packaging system for a capacitor and inductor

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.

Variable voltage, variable capacitance chip capacitor device having lead

An electrochemical cell (10) having a first electrode (20) and second electrode (80) and a separator (40) disposed therebetween further includes a layer of material disposed between at least one of the electrodes and the separator (52). The layer (52) is adapted to reduce the likelihood of cell failure by subduing the dendritic growth of at least one of the electrodes. The layer (52) is a layer of a metal mesh screen and may further be adapted to be used as the current collector for collecting current generated by the cell (10).
