Abstract
A capacitor includes a porous pellet formed from compressed conductive particles. The pellet has a lead receiving external surface. The conductive particles at the lead receiving surface are fused together to create a fused layer on the external surface of the pellet. A lead wire has one of its ends welded to the fused layer on the surface of the pellet. The fused layer is formed by exposing it to high temperatures, preferably by use of a laser beam.
Claims7
A capacitor comprising:
- a porous pellet comprised of compressed conductive particles, said pellet having a lead receiving external surface;
- said conductive particles at said lead receiving surface being fused together to create a fused layer on said external surface of said pellet;
- a lead wire having first and second ends;
- said first end of said lead wire being welded to said fused layer of said lead receiving surface.
A capacitor comprising a porous pellet comprised of compressed conductive particles, said pellet having an external surface, and a lead wire having one end welded to said external surface of said pellet, said capacitor being made according to a method comprising:
- fusing a quantity of said compressed conductive particles
- together to create a fused layer of said particles in a
- localized area of said external surface of said pellet.
