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
