Abstract: A tantalum capacitor includes: a tantalum body comprising tantalum powder and a tantalum wire exposed to one end surface; an anode lead frame comprising a first electrode member and a second electrode member bent perpendicularly thereto; a cathode electrode lead frame comprising a third electrode member spaced apart from the first electrode member having the tantalum body mounted on an upper surface thereof and a fourth electrode member bent perpendicularly thereto; and a encapsulation portion covering the tantalum body so that lower surfaces of the first and third electrode members and one external surfaces of the second and fourth electrode members are exposed. The anode lead frame comprises a bend portion having a connection part of the first electrode member and the second electrode member as an axis, and an end of the bend portion is in contact with the tantalum wire.

Abstract: A tantalum capacitor includes a tantalum body comprising a tantalum sintered body containing tantalum powder, a conductive polymer layer disposed on the tantalum sintered body and including a first filler as a non-conductive particle, and a tantalum wire. The first filler includes a core including at least one metal oxide among BaTiO3, Al2O3, SiO2 and ZrO2, and a coating film disposed on a surface of the core.
