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 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
2
tantalum capacitors
operated at 50% of rated voltage.
The T521 Series High Voltage Polymer Tantalum is designed
for higher application voltages such as 12V, 24V and 28V
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 voltage 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.
Benefits
Voltage ratings to 35V
Volumetric efficiency
Stable temperature characteristics
Up to 68μF capacitance value
High ripple current capability
Low ESR
High reliability
Low profile design
Benign failure mode
Pb Free when ordered with 100% Sn termination
RoHS compliant and Halogen Free
Applications
Typical applications include DC/DC converters, power supply
input and higher voltage applications such as 12V to 28V power
input rails in the military/aerospace and industrial markets.
Environmental Compliance
*When ordered with 100% Sn Solder
RoHS Compliant (6/6)* according to Directive 2002/95/EC
