Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
136 words
A non-hermetically sealed capacitor resistant to heat degradation up to 275 degrees centigrade comprising a processed chip; said processed chip including at least a solid electrolyte; a dielectric layer; a semi-conductive layer; a conductive layer; and an anode lead, a conductive metal container open at one end, said container including a moisture-proof conductive void-free adhesive material, said container dimensioned to snugly receive said chip, said adhesive material in said container in a volumetric amount to substantially engage said chip free of said lead without voids between said container and said chip, a moisture-proof non-conductive plastic seal, said non-conductive plastic seal adapted to seal said open end of said metal container with said anode lead extending therethrough, said adhesive material and said chip in said container with said plastic seal substantially free of all moisture and voids.
Claim 2
Dependent Claim
136 words
A non-hermetically sealed capacitor resistant to heat degradation up to 275 degrees centigrade comprising a processed chip; said processed chip including at least a solid electrolyte; a dielectric layer; a semi-conductive layer; a conductive layer; and an anode lead, a conductive metal container open at one end, said container including a moisture-proof conductive void-free adhesive material, said container dimensioned to snugly receive said chip, said adhesive material in said container in a volumetric amount to substantially engage said chip free of said lead without voids between said container and said chip, a moisture-proof non-conductive plastic seal, said non-conductive plastic seal adapted to seal said open end of said metal container with said anode lead extending therethrough, said adhesive material and said chip in said container with said plastic seal substantially free of all moisture and voids.
Claim 3
Dependent Claim
14 words
