Reduced Leakage Polymer Tantalum SMT Capacitors - T522 Series

The KEMET organic capacitor (KO-CAP) is a tantalum capacitor with a Ta anode and Ta₂O₅ dielectric. A conductive organic polymer replaces the traditionally used MnO₂ as the cathode plate of the capacitor. This results in very low ESR and improved capacitance retention at high frequency. The KO-CAP also exhibits a benign failure mode which eliminates the ignition failures that can occur in standard MnO₂ tantalum types. KO-CAPs may also be operated at steady state voltages up to 90% of rated voltage.

The T522 reduced leakage polymer tantalum series is designed to meet the needs of leakage-sensitive applications such as battery-supported circuits. The T522 series offers some of the lowest leakage values available in polymer tantalum capacitors with upper leakage limits that are up to 70% lower than other polymer series.
