Document Type and Number:
Japanese Patent JP4084391
Kind Code:
B2
Abstract:
A multiterminal-pair solid electrolytic capacitor employing a two-terminal type capacitor element is provided. In the solid electrolytic capacitor 10 in accordance with the present invention, anode terminal patterns 42 A (and anode terminals 43 A) are connected to an anode part 24 of a capacitor element 12 through anode vias 44 A formed in a substrate 14 and an anode pattern 38 D formed on a element carrying surface 14 a. On the other hand, cathode terminal patterns 42 B (and cathode terminals 43 B) are connected to a cathode part 28 on the surface of an accumulator 26 of the capacitor element 12 through cathode vias 44 B formed in the substrate 14 and cathode patterns 38 A to 38 C formed on the element carrying surface 14 a. Therefore, when the solid electrolytic capacitor 10 is mounted on a packaging substrate from the mounting surface 14 b side while a predetermined voltage is applied to four pairs of anode terminals 43 A and cathode terminals 43 B formed on the mounting surface 14 b, the solid electrolytic capacitor 10 functions as a four-terminal-pair solid electrolytic capacitor.
