A capacitor includes an anode body and a housing having a base surface. The housing encloses the anode body at least partially. The capacitor also includes an anode connector and an anode contact that extends outward from an interior of the anode body. The anode contact has a flat side. The anode connector includes a surface containing a soft-solderable material, and a segment running along the base surface of the housing that forms a soldering surface.
1. A capacitor comprising:
an anode body;
a housing having a base surface and enclosing at least said anode body;
an anode contact extending outward from the interior of said anode body, said anode contact having at least one fiat surface;
an anode connector having flat opposing surfaces formed; a) from a metal; b) welded to said anode contact; c) soft-solderable to another surfaces; and d) formed both to contact said anode contact and to be parallel to said base surface.
2. A capacitor according to claim 1 wherein said anode contact contains a refractory metal.
3. A capacitor according to claim 2 wherein said refractory metal is selected from the group consisting of titanium, zirconium, hafnium, tantalum, niobium, vanadium, tungsten and molybdenum.
4. A capacitor according to claim 1 wherein said anode contact contains a non-solderable metal.
5. A capacitor according to claim 4 wherein said non-solderable metal is selected from the group consisting of zirconium, tantalum, niobium, molybdenum and tungsten.
6. A capacitor according to claim 1 wherein said anode connector is formed from a soft-solderable metal selected from the group consisting of nickel, copper, cobalt, tin, precious metals and steel and their alloys.
7. A capacitor according to claim 1 wherein said anode contact and said anode connector are the same width.
8. A capacitor according to claim 1 wherein said anode contact and said anode connector have different widths.
9. A capacitor according to claim 8 wherein said anode connector is wider than said anode contact.
10. A capacitor according to claim 8 wherein said anode connector has a soft-solderable surface in the plane of said housing base surface which conforms to a standard case size for a surface mount capacitor.
11. A capacitor according to claim 1 wherein said anode contact is welded to said anode connector within said housing.
12. A capacitor according to claim 11 wherein said anode contact projects from the plane of said anode body and is welded to said anode connector in that plane.
13. A capacitor according to claim 1 wherein said anode contact is welded to said anode connector outside of said housing.
14. A capacitor according to claim 13 wherein said anode contact is bent in the direction of toward said housing base surface and welded to said anode connector along that direction.
