KEMET Organic Capacitor (KO-CAP)
T521 High Voltage Polymer Tantalum
Overview
The KEMET Organic Capacitor (KO-CAP) is a tantalum
capacitor with a Ta anode and Ta 2 O 5 dielectric. A conductive
organic polymer replaces the traditionally used MnO 2 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 2 tantalum types.
KO-CAPs may also 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 MnO 2 tantalum capacitors
operated at 50% of rated voltage.
Benefits
The T521 Series High Voltage Polymer Tantalum is designed
for higher application voltages such as 12 V, 24 V, 28 V, and 48
V input rails. This series demonstrates excellent high voltage
handling capabilities and reliability and is commonly selected
as a replacement for other high capacitance dielectrics such as
MnO 2 tantalum and aluminum electrolytic capacitors. The T521
Series can be safely operated at 80% of the rated voltages and
can withstand transient conditions up to the rated voltage of the
component. This series offers higher capacitance for a given
application voltage when compared to multilayer ceramic and
tantalum MnO 2 devices. The T521 Series also offers superior
ESR performance over tantalum MnO 2 and aluminum electrolytic
capacitors and a much lower profile than aluminum polymer and
aluminum electrolytic capacitors.
