Abstract
A tantalum capacitor includes a capacitor body; a tantalum wire protruding from one surface of the capacitor body; a molded part enclosing the capacitor body and the tantalum wire; an anode lead frame connected to the tantalum wire and exposed to an outer surface of the molded part; and a cathode lead frame disposed on an outer surface of the capacitor body and exposed to the outer surface of the molded part. The anode lead frame includes a bend portion.
Claims11
A tantalum capacitor comprising:
- a capacitor body;
- a tantalum wire protruding from one surface of the capacitor body and having an anode part and a cathode part;
- a molded part enclosing the capacitor body and the tantalum wire;
- an anode lead frame inclinedly contacting the tantalum wire, bent only once in a lengthwise direction of the tantalum wire, and exposed to an outer surface of the molded part;
- and
- a cathode lead frame disposed on an outer surface of the capacitor body and exposed to the outer surface of the molded part,
- wherein the anode lead frame includes a bend portion,
- wherein the bend portion has an acute angle of 80° or less,
- wherein the anode lead frame further includes a groove portion having a width greater than a width of the tantalum wire,
- wherein the anode part of the tantalum wire is in direct contact with the anode lead frame, and
- wherein the cathode part of the tantalum wire is disposed to be spaced apart from the anode lead frame and overlaps the groove portion from a viewpoint in a vertical direction perpendicular to a direction in which the tantalum wire extends from the capacitor body.
