KEMET Organic Capacitor (KO-CAP)
T545 Series High Energy Polymer Tantalum
Overview
The KEMET Organic Capacitor 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 polymer technology also exhibits a benign failure mode which eliminates the ignition failures that can occur in standard MnO2 tantalum types. Ta polymers may be operated at voltages up to 90% of rated voltage for part types with rated voltages of ≤ 10 volts and up to 80% of rated voltage for part types > 10 volts with equivalent or better reliability than traditional MnO2 tantalum capacitors operated at 50% of rated voltage.
