Abstract
A copper-encased flat electrolytic capacitor is produced by sealing the capacitor unit in a heat-sealable polymer-copper laminate. The polymer side of the laminate is adjacent the capacitor section, and the copper side forms the exterior of the sealed unit. Leads may be attached to opposite surfaces of the capacitor, or electrical connection may be made prior to sealing, e.g., to leg-like extensions of the laminate that, after sealing, serve as the leads.
