KEMET Organic Capacitor (KO-CAP)
T520 Series Polymer Tantalum
Overview
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%ꢀofꢀratedꢀvoltageꢀforꢀpartꢀtypesꢀwithꢀratedꢀvoltagesꢀofꢀ≤ꢀ10ꢀ
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.
The T520 Series KO-CAP Low ESR Polymer captures the
best features of multilayer ceramic (low ESR, high frequency
capacitance retention), aluminum electrolytic (higher capacitance,
benign failure mode), and proven solid tantalum technology
(volumetricꢀefficiency,ꢀsurfaceꢀmountꢀcapability,ꢀextremelyꢀlongꢀ
life). The T520 can reduce component counts, eliminate through-
hole assembly by replacing cumbersome leaded aluminum
capacitors, and offer a cost-effective and space-saving solution.
