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 Ta

dielectric. A conductive

organic polymer replaces the traditionally used MnO

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 MnO

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 MnO

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.
