In summary, KEMET’s KO-CAP, the T521 Series High Voltage Polymer Tantalum, is designed for higher application voltages such as 12V, 24V, 28V, and 48V input rails. This series demonstrates excellent high voltage handling capabilities and reliability and is commonly selected as a replacement for other high capacitance dielectrics such as MnO2 tantalum and aluminum electrolytic capacitors. The T521 Series can be safely operated at 90% of the rated voltages and can withstand transient conditions up to the rated voltage of the component. This series offers higher capacitance for a given application voltage when compared to multilayer ceramic and tantalum MnO2 devices. The T521 Series also offers superior ESR performance over tantalum MnO2 and aluminum electrolytic capacitors and a much lower profile than aluminum polymer and aluminum electrolytic capacitors. Polymer Technology continues to expand into higher voltage applications.
