The utility model discloses a positioning leading-out terminal capacitor, comprising a shell [3], a core arranged in the shell [3] and a leading-out terminal [1] electrically connected with two ends of the core. The positioning leading-out terminal capacitor is characterized in that the leading-out terminal [1] consists of a positioning leading-out surface and a welding surface that form a 90-degree angle; and the lower part of the leading-out terminal [1] extends to the bottom part of the core. In the utility model, the leading-out terminal is well contacted with the core; the stability of the capacitor is increased, and the risk on faulty welding and untight insertion is small.
