Abstract
A charge transfer complex comprising N,N'-alkylene-di-3,5-lutidine as a donor and 7,7,8,8-tetracyanoquinodimethane as an acceptor, the molar ratio of the acceptor to the donor of the charge transfer complex being between 3.0 and 5.0 has a high melting point and excellent electrical conductivity as an electrolyte for a capacitor. A solid electrolytic capacitor employing said charge transfer complex has reduced current leakage and high temperature load characteristics. A chip-type solid electrolytic capacitor employing said charge transfer complex has reduced current leakage, high temperature load characteristics and excellent thermal stability and life characteristics.
