T520 fiche technique
KEMET Organic Capacitor (KO-CAP) – Low ESR
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% 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.
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
(volumetric efficiency, surface mount capability, extremely long
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.
