Tantalum Polymer Capacitors

KEMET Tantalum Polymer Capacitors are specially designed as a capacitance solution for applications seeking low ESR, high capacitance, long life, small case size, low profile, and high ripple handling. The use of a solid electrolytic capacitor in combination with a conductive polymer cathode yields the most energy-dense capacitance solution available in the world with the lowest possible ESR.
