Patent ID: 8599539

Claim:
A ceramic chip assembly comprising: a ceramic base having electrical characteristics; a pair of electrodes disposed on a pair of opposing surfaces of the ceramic base; a pair of metal lead wires having first ends electrically and mechanically connected to the electrodes, and second ends at opposite sides from the first ends of the metal lead wires; an insulation sealant covered to seal the ceramic base, the electrodes, and the first ends of the metal lead wires while exposing the metal lead wires adjacent the second ends thereof; and an insulation polymer coating layer covered on an entire external surface of the insulation sealant and portions of the metal lead wires exposed out of the insulation sealant except distal end portions at the second ends of the metal lead wires, wherein the insulation polymer coating layer has a varying thickness which gradually increases as it approaches from the distal end portions toward proximal portions of the metal lead wires, and defines a maximum thickness at a region of the insulation sealant opposite to the distal end portions of the metal lead wires.
