Dry tantalum electrolytic capacitors are widely used in electronic equipment because they have high capacitances at useful working voltages, low effective series resistances, relatively long life, and a small footprint. Tantalum capacitors have some limitations as well that, if not taken into account during circuit design, may produce catastrophic failures. The effect of one such limitation is highlighted in this detailed and well-illustrated case study.
