Abstract
Abstract A portion of the anode lead of a solid electrolyte capacitor is offset so that the remaining portion of the anode lead is coaxial with the anode riser, and these and the cathode lead are coplanar. The offset portion of the anode lead is bent transversely, and the riser is connected to this transverse. Preferably, the anode lead and the cathode lead are of different diameters.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
158 words
A solid electrolyte capacitor comprising a capacitor body having a conductive cathode coating, a riser extending from said body and isolated from said coating, a cathode lead wire in contact with said coating, an anode lead wire in contact with said riser, and a molded encapsulating material surrounding and enclosing said body, said riser, and portions of said lead wires to form a case, said anode lead wire having three spaced apart elbows forming an offset bent transverse portion and a non-offset portion; said riser and said non-offset portion of said anode lead wire being coaxial with each other; two of said elbows offsetting said bent portion a spaced distance from said riser and said non-offset portion, the third of said elbows forming said bent transverse portion, said contact of riser to anode lead wire being at said bent transverse portion, and said transverse portion and said offset portion of said lead wire being enclosed in said case.
Claim 2
Dependent Claim
158 words
A solid electrolyte capacitor comprising a capacitor body having a conductive cathode coating, a riser extending from said body and isolated from said coating, a cathode lead wire in contact with said coating, an anode lead wire in contact with said riser, and a molded encapsulating material surrounding and enclosing said body, said riser, and portions of said lead wires to form a case, said anode lead wire having three spaced apart elbows forming an offset bent transverse portion and a non-offset portion; said riser and said non-offset portion of said anode lead wire being coaxial with each other; two of said elbows offsetting said bent portion a spaced distance from said riser and said non-offset portion, the third of said elbows forming said bent transverse portion, said contact of riser to anode lead wire being at said bent transverse portion, and said transverse portion and said offset portion of said lead wire being enclosed in said case.
Claim 3
Dependent Claim
18 words
A capacitor according to claim 1 wherein said bent transverse portion of said anode lead wire is flattened.
Claim 4
Dependent Claim
32 words
A capacitor according to claim 1 wherein said spaced distance is the sum of the radii of said riser and of said bent and flattened transverse portion of said anode lead wire.
Claim 5
Dependent Claim
36 words
A capacitor according to claim 1 wherein said cathode lead wire is attached to one side of said pellet, and said non-offset portion of said anode lead wire is coplanar with said side of said pellet.
Claim 6
Dependent Claim
20 words
A capacitor according to claim 1 wherein said anode lead wire is of different diameter than said cathode lead wire.
Claim 7
Dependent Claim
20 words
A capacitor according to claim 5 wherein said anode lead wire is of larger diameter than said cathode lead wire.
