Abstract
A tantalum chip capacitor with a cut-grooved anode lead frame is disclosed. The cut-grooved lead frame is designed to allow the tantalum element set in the small-sized epoxy mold package of the capacitor to have a desired size, thus restricting an increase in impedance of the tantalum chip capacitor regardless of a reduction in the size of the package according to the recent trend of smallness of the tantalum chip capacitors. This tantalum chip capacitor has a tantalum element, a anode lead wire extending from the tantalum element, and a cathode lead frame attached at its inside end to the tantalum element and forming a mounting terminal at its outside end. The cut-grooved anode lead frame is welded at its inside end to the lead wire while overlapping a part of the lead wire at the inside end having the cut groove. This anode lead frame also forms a mounting terminal at its outside end. A mold package encloses the tantalum element, the lead wire, a part of the cathode lead frame attached to the tantalum element, and a part of the anode lead frame welded to the lead wire.
