Abstract
A hermetically sealed capacitor including a metal tape (e.g, copper) having an adhesive on one side and being folded and wrapped around the capacitor winding in the manner that a Christmas package is wrapped. After wrapping, the tape initially extends beyond both ends of the capacitor. The tape is then folded at one end of the capacitor. The seam of the tape overlapping itself (along the length of the capacitor) and the fold at the one end of the capacitor are each soldered. On the other end of the capacitor, a ceramic header having a through hole (for one of the capacitor leads) is positioned. The tape extends beyond the ceramic header and is folded so as to make contact with the ceramic header. The seam between the metal tape and the ceramic piece is then soldered. In this way, a small, hermetically sealed capacitor is obtained.
