  • Patent number: 4771363
    Abstract: A hermetically sealed capacitor comprises a generally cylindrical ceramic tube having opposite annular tube ends that are generally parallel to each other; a generally cylindrical capacitor element within the tube; and a pair of metal end caps, each including a receptacle defined by a generally circular end wall portion, an integral tube wall portion, and an integral terminal. The inner diameter of the tube wall portion is slightly larger than the outer diameter of the ceramic tube portion so as to provide, during assembly of the capacitor, an aligning guide for disposing the ceramic tube end within the receptacle. A pair of parallel disk-shaped soldered bonds are provided; each bonding one of the end caps to one of the tube ends so that the ceramic case, the end caps, and the bonds provide a hermetically sealed case for the capacitor element.
