There is disclosed herein a high voltage and high temperature power electronics capacitor which comprises one or more insulator layers of mica paper, and one or more metal conductor layers, all dispersed in a pressurized environment of a nonreactive and high voltage strength gas maintained at near ambient to about 405.2 kPa of pressure. The insulator and conductor layers are isolated and separated from one another by the alternating placement of conductor layers between said insulator layers. These capacitors are readily packaged for commercial use in containers or housings of almost any geometric form and any material of construction. Moreover, low inductance ceramic bushings can be employed on these containers for establishing external electrical contacts. These capacitors can be economically manufactured and used in large commercial volumes with currently available materials and production methods.
