摘要： An improved capacitor, and method of manufacturing the improved capacitor, is provided. The method includes deoxygenating and leaching the anode wire to produce a capacitor comprising an anode having a surface area of at least 4.0 m2/g or a charge density of at least 200,000 CV/g with the anode wire having an equivalent diameter of less than 0.30 mm extending from said anode. A dielectric is on the anode and a cathode is on the dielectric.

摘要： An improved capacitor is provided wherein the capacitor has an improved bond between the anode and anode wire. The anode comprises a pressed anode powder comprising a first density region and a second density region wherein the second density region has a higher density than the first density region. An anode wire extends into the second density region wherein the anode wire in the second density region is distorted by compression. This allows for better utilization of the metal powder surface area by allowing a lower bulk press density and lower sinter temperature while still achieving the necessary wire pull strength. In addition, this invention when utilized with deoxidation steps, results in sufficient wire pull strengths not possible otherwise.

摘要： 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.
