Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
77 words
A chip type capacitor comprising at least two sides of opposite polarities and a termination means wherein the termination means includes a riser means in electrical contact with at least one of the sides, an elongated metal containing member joined to the riser means, and a metal containing end cap over the riser means having electrically conductive adhesive material therebetween whereby the metal containing end cap is electrically and mechanically coupled to the elongated metal containing member.
Claim 2
Dependent Claim
77 words
A chip type capacitor comprising at least two sides of opposite polarities and a termination means wherein the termination means includes a riser means in electrical contact with at least one of the sides, an elongated metal containing member joined to the riser means, and a metal containing end cap over the riser means having electrically conductive adhesive material therebetween whereby the metal containing end cap is electrically and mechanically coupled to the elongated metal containing member.
Claim 3
Dependent Claim
51 words
The capacitor of claim 1 further comprising an anode containing film forming metal, a dielectric oxide film over the anode, a cathode including solid electrolyte over the dielectric oxide film and at least one electrically conductive layer over the electrolyte, and the riser means of the termination extends from the anode.
Claim 4
Dependent Claim
20 words
The capacitor of claim 2 also including electrically insulating material over at least a portion of the electrically conductive layer.
Claim 5
Dependent Claim
