Abstract
The tantalum chip capacitor of the present invention includes a anode terminal which is substantially flat. The tantalum wire which extends from the tantalum pellet through the insulating material terminates substantially flush with the insulating material, allowing the termination materials to be applied over a substantially flat surface. The tantalum chip capacitors of the present invention are created by methods which include the step of grinding the anode end of the capacitor so that the tantalum wire is flush with the insulating material. Conductive materials can then be applied to the anode end of the capacitor creating a substantially flat anode terminal.
