Jonathan Paulsen 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).

  • Apparatus and Method for Screening Electrolytic Capacitors
    Publication number: 20130241591
    Abstract: A method for screening electrolytic capacitors places a capacitor in series with a resistor, applying a test voltage and following the charge curve for the capacitor. A high voltage drop across the capacitor indicates high reliability and a low voltage drop is used to reject the piece. The leakage current is not adversely affected during the test.
    Type: Application
    Filed: May 6, 2013
    Publication date: September 19, 2013
    Applicant: Kemet Electronics Corporation
    Inventors: Jonathan Paulsen, Erik Karlsen Reed, Yuri Freeman
