Description

ABSTRACT:
A high energy density, high power density capacitor having an energy density of at least about 0.5 J/cm.sup.3 is provided. The capacitor comprises a plurality of interleaved metal electrode layers separated by a polymer layer. The interleaved metal electrode layers terminate at opposite ends in a solder termination strip. The high energy density aspect of the capacitors of the invention is achieved by at least one of the following features: (a) the dielectric thickness between the interleaved metal electrode layers is a maximum of about 5 .mu.m; (b) the polymer is designed with a high dielectric constant .kappa. of at least about 3.5; (c) the metal electrode layers within the polymer layer are recessed along edges orthogonal to the solder termination strips to prevent arcing between the metal electrode layers at the edges; and (d) the resistivity of the metal electrode layers is within the range of about 10 to 500 ohms per square, or a corresponding thickness of about 200 to 30 .ANG..
