Abstract
An improved high voltage ceramic capacitor is disclosed which includes a ceramic body having electrode layers formed on opposite sides thereof. Novel terminals formed of material having a coefficient of expansion which is the same as, or nearly the same as, the material of the ceramic body are bonded to the electrode layers to prevent voids resulting from thermal stresses.
Claims10
A high tension ceramic condenser comprising:
- a ceramic dielectric having two parallel surfaces;
- an electrode layer formed on each of said parallel surfaces of said ceramic dielectric;
- a terminal separate from the electrode layer having an expansion coefficient which is substantially the same as the expansion coefficient of said ceramic dielectric, said terminal being joined by solder or an electroconductive adhesive to at least one of said electrode layers;
- and,
- a synthetic resin covering at least part of said electrode layers.
