A tantalum capacitor includes a tantalum body having one surface which a tantalum wire extends from, a molded portion including first and second surfaces facing each other in a first direction and third and fourth surfaces facing each other in a second direction, and surrounding the tantalum body, a first lead frame including a first electrode portion in contact with the second surface of the molded portion, a second electrode portion connected to the first electrode portion, a third electrode portion connected to the second electrode portion, and a fourth electrode portion connected to the third electrode portion and the tantalum wire, and a second lead frame disposed to be in contact with the second surface of the molded portion and spaced apart from the first lead frame. The second electrode portion and the third electrode portion are inclined in different directions with respect to the second surface.

Tantalum capacitor having lead frame including plural electrode portions inclined in different directions

A tantalum capacitor includes: a tantalum body having a tantalum wire exposed from one surface of the tantalum body; a molded portion including first and second surfaces opposing in a thickness direction, third and fourth surfaces opposing in a width direction, and fifth and sixth surfaces opposing in a longitudinal direction, the molded portion surrounding the tantalum body; an anode lead frame including an anode connection member and an anode terminal, which are connected to the tantalum wire, exposed through the second surface of the molded portion; and a cathode lead frame spaced apart from the anode lead frame, and exposed through the second surface of the molded portion, wherein end portions of the tantalum wire, the anode connection member, and the anode terminal in the longitudinal direction are on a same plane.

Tantalum capacitor and manufacturing method thereof

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.

Tantalum capacitor

The present invention relates to a solid electrolytic capacitor and a production method thereof. A solid electrolytic capacitor of the present invention includes: a capacitor element having an anode wire inserted in one side surface thereof; a cathode terminal disposed on one side under the capacitor element to be electrically connected to the capacitor element; an anode terminal disposed on the other side under the capacitor element and having a bending portion integrally formed to be inclined to the capacitor element for electrical connection with the anode wire; and a molding portion surrounding the outside of the capacitor element and formed to expose lower surfaces of the cathode terminal and the anode terminal.

Solid electrolytic capacitor and production method thereof

There is provided a tantalum capacitor including: a capacitor body containing tantalum powder and having a tantalum wire exposed to one end thereof; a positive electrode lead frame including a positive electrode terminal part and a positive electrode connection part formed by upwardly bending a portion of the positive electrode terminal part from the outside toward the inside and connected to the tantalum wire; a negative electrode lead frame having the capacitor body mounted thereon; and a molded part formed to enclose the capacitor body while exposing a lower surface of the positive electrode terminal part of the positive electrode lead frame and a lower surface of the negative electrode lead frame.
