20130279077 | Solid Electrolytic Capacitor Containing Multiple Sinter Bonded Anode Leadwires - A capacitor containing a solid electrolytic capacitor element having a porous anode body and an anode lead assembly is provided. At least one wire of the lead assembly is electrically connected to the anode body for connection to an anode termination.

This combination of characteristics can increase the mechanical robustness of the part and improve its electrical performance. | 10-30-2014 |
