compact, low-voltage devices up to several hundred µF, these have a lower energy density and are more accurate than aluminum electrolytics. These capacitors are comprised of a permeable tantalum cneter section surrounded by tantalum pentoxide. A tantalum wire is inserted into the center section and then extends axially from the component. There are many advantages of using tantalum capacitors over other types - They have higher volumetric efficiency (CV/cc); They have superior frequency characteristics; They are highly reliable and do not degrade over time. Tantalum capacitors do not lose capacitance like electrolytic capacitors. Unlimited shelf life.
