Douglas Edson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Electrolytic Capacitor with Improved Volumetric Efficiency
    Publication number: 20080062617
    Abstract: Surface mount electrolytic capacitors are provided with anode and cathode terminations having respective first termination portions provided on the bottom surface of a molded package in a generally coplanar configuration. A second cathode termination portion is bent in a generally perpendicular fashion to the first cathode termination portion and may then be adhered to the external cathode layer of a capacitor body. A second anode termination portion is bent in a generally perpendicular fashion to the first anode termination portion and may then be welded to an anode wire connected to and extending from the capacitor body. An insulation pad may be provided between the first anode termination portion and the capacitor body to prevent device shorting. A planar termination frame may be provided to form the electrolytic capacitors of the present subject matter.

  • Electrolytic capacitor with a thin film fuse
    Publication number: 20070109727
    Abstract: The present technology relates to fused capacitor structures provided with a leadframe design configured to accepting a plurality of selectively placed fuses. The leadframe and fuse configuration enables construction of fused capacitors exhibiting low Equivalent Series Resistance (ESR) and allows construction of a variety of fuse configuration using a single leadframe design.
