Tantalum capacitor including conductive polymer layer having a filler

A tantalum capacitor comprising:

• a tantalum body comprising a sintered tantalum body including tantalum particle, a conductive polymer layer disposed on the sintered tantalum body and including a first filler, and a tantalum wire penetrating through at least a portion of each of the sintered tantalum body and the conductive polymer layer in a first direction,
• wherein a ratio of an area of the first filler to an area of the conductive polymer layer is 0.55 or more and less than 0.83 in a first cross-section partially overlapping the sintered tantalum body, among cross-sections perpendicular to the first direction.

A tantalum capacitor comprising:

• a tantalum body comprising a sintered tantalum body including tantalum particle, a conductive polymer layer disposed on the sintered tantalum body and including a first filler, and a tantalum wire penetrating through at least a portion of each of the sintered tantalum body and the conductive polymer layer in a first direction,
• wherein a ratio of an area of the first filler to an area of the conductive polymer layer is greater than 0.38 in a first cross-section, perpendicular to the first direction and cutting a length of the sintered tantalum body in the first direction by 2:1.
