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 BaTiO, AlO, SiOand ZrO, and a coating film disposed on a surface of the core.

Tantalum capacitor

A tantalum capacitor includes a tantalum body having a tantalum wire exposed from one surface; a positive electrode terminal including a first electrode portion connected to the tantalum wire and a second electrode portion connected to be perpendicular to the first electrode portion; wherein the first electrode portion includes a first protrusion disposed in a tantalum wire direction, and the tantalum wire includes a first groove disposed in a tantalum body direction, wherein the first groove and the first protrusion are connected to each other.

A tantalum capacitor includes a tantalum body, an encapsulation portion, first and second external electrodes spaced apart from each other on a lower surface of the encapsulation portion, a first plating layer disposed on one end surface of the encapsulation portion and a lower surface of the first external electrode to electrically connect the first external electrode and the tantalum body, an upper end of the first plating being comprised of a first bonding force improving portion contacting one upper edge of the encapsulation portion, and a second plating layer disposed on the other end surface of the encapsulation portion and a lower surface of the second external electrode to electrically connect the second external electrode and an exposed portion of a tantalum wire, an upper end of the second plating layer being comprised of a second bonding force improving portion contacting the other upper edge of the encapsulation portion.

A tantalum capacitor includes a tantalum body including tantalum powder, and having a tantalum wire exposed to one end surface; a molding portion including fifth and sixth surfaces opposed in a first direction, third and fourth surfaces opposed in a second direction, and first and second surfaces opposed in a third direction, and formed to surround the tantalum body; an anode lead frame exposed to the second surface of the molding portion, and connected to the tantalum wire; and a cathode lead frame spaced apart from the anode lead frame, and exposed to the second surface of the molding portion. The anode lead frame includes a first connection portion and a first bent portion, and the first bent portion forms an inclination angle within a range of less than 70&#xb0; toward the tantalum body, based on the first connection portion.

Tantalum capacitor including body and lead frame having bent portion forming inclination angle toward the body

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.
