Hermetically sealed wet electrolytic capacitor

A hermetically sealed wet electrolytic capacitor includes a hermetically sealed case, a cathode, an anode, and an insulator between the anode and the cathode to provide electrical insulation between the anode and the cathode. An electrolytic solution is disposed within the case. A first terminal is...

More Information
Summary:A hermetically sealed wet electrolytic capacitor includes a hermetically sealed case, a cathode, an anode, and an insulator between the anode and the cathode to provide electrical insulation between the anode and the cathode. An electrolytic solution is disposed within the case. A first terminal is electrically connected to the anode and a second terminal is electrically connected to the cathode. The cathode comprises a metal substrate having an alloy layer formed with a noble metal and a noble metal/base metal electrode element layer electrochemically deposited thereon. The electrolytic solution has a conductivity between 10 and 60 mS/cm. The capacitor may be used in an implantable device.
