1. Feedthrough pin of an electrolytic capacitor for contacting an electrode of the electrolytic capacitor and providing an electrical contact of the electrolytic capacitor on an outside of the electrolytic capacitor, the feedthrough pin comprising a longitudinally extending body,
a first circumferential protrusion that is capable of assuring position is arranged between a first section of the longitudinally extended body wherein the first circumferential protrusion runs around a longitudinal axis and a second section of the longitudinally extended body and does not introduce mechanical deformation to the first circumferential protrusion, wherein the first circumferential protrusion runs around a longitudinal axis of the longitudinally extended body and extends radially outwards over an outer contour of the first section of the longitudinally extended body and an outer contour of the second section of the longitudinally extended body and said first circumferential protrusion partially extends over a top surface of a feedthrough flange.
