KEMET 470μF Surface Mount Polymer Capacitor, 2.5V dc

KEMET T520 Series (KO-CAP) polymer tantalum capacitors offer the best features of multilayer ceramic (low ESR, high frequency capacitance retention), aluminium electrolytic (higher capacitance, benign failure mode), and proven solid tantalum technology (volumetric efficiency, surface mount capability, extremely long life).
The KEMET T520 Organic Capacitor (KO-CAP) is a tantalum capacitor with a Ta anode and Ta2 O5 dielectric. A conductive organic polymer replaces the traditionally used cathode plate of the capacitor. This results in very low ESR and improved capacitance retention at high frequency.
