Title
(EN) Chip-type aluminum electrolytic capacitor
Abstract
(EN)

A chip-type aluminum electrolytic capacitor is provided that allows a lead wire exposed from an insulated terminal plate to have an increased temperature sooner than the other parts to provide highly-reliable soldering in a relatively-easy reflow atmosphere environment and that has a superior vibration resistance. The capacitor includes an insulated terminal plate (3) that includes, at the outer surface thereof, an insertion hole (2a) to which a pair of lead wires (2) introduced from a sealing member of a capacitor body are inserted and a first concave groove (2a) for storing lead wires (2) inserted to the hole while lead wires (2) being bent in an orthogonal direction. Insulated terminal plate (3) is attached to the capacitor so as to be abutted with the above sealing member. Metal electrode (4) is buried in an inner face of first concave groove (2a) provided in insulated terminal plate (3) and the periphery thereof. A part of metal electrode (4) is exposed at end face section (3a) of insulated terminal plate (3). The capacitor also has bidirectional second concave groove (6) that extends from the insertion hole of insulated terminal plate (3) to end sections (3a1, 3a2) of the insulated terminal plate.
