Abstract
A solid electrolytic capacitor includes a capacitor element and a resin package enclosing the capacitor element. Two anode leads, partially enclosed by the package, are connected to the opposite ends of the anode bar that are allowed to protrude in the opposite directions from an anode chip of the capacitor element. The capacitor element is provided with a cathode layer connected to an external cathode electrode arranged between the paired anode leads. With this symmetrical structure of two anode leads and one cathode electrode, the solid electrolytic capacitor can be mounted onto a printed circuit board without worrying about the polarity of the capacitor. Further, the proximity of the cathode electrode and the respective anode leads serves to reduce the self-induction in a high-frequency range.
