Applications
Typical applications include DC/DC converters, power supply
input and higher voltage applications such as 12 V to 50 V power
input rails in the military/aerospace and industrial markets.
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 T521 Series High Voltage Polymer Tantalum is designed
for higher application voltages such as 12 V, 24 V and 28 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
MnO2 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 MnO2 devices. The T521 Series also offers superior
ESR performance over tantalum MnO2 and aluminum electrolytic
capacitors and a much lower prole than aluminum polymer and
aluminum electrolytic capacitors.

Ripple Current/Ripple Voltage
Permissible AC ripple voltage and current are related to equivalent series resistance (ESR) and the power dissipation capabilities of the
device. Permissible AC ripple voltage which may be applied is limited by two criteria:
1) The positive peak AC voltage plus the DC bias voltage, if any, must not exceed the DC voltage rating of the capacitor.
2) The negative peak AC voltage, in combination with bias voltage, if any, must not exceed the allowable limits specied for
reverse voltage. See the Reverse Voltage section for allowable limits.
The maximum power dissipation by case size can be determined using the below left table. The maximum power dissipation rating
stated in the table must be reduced with increasing environmental operating temperatures. Please refer to the below right table for
temperature compensation requirements.

Density Level A: For low-density product applications. Recommended for wave solder applications and provides a wider process window for reow solder processes.
Density Level B: For products with a moderate level of component density. Provides a robust solder attachment condition for reow solder processes.
Density Level C: For high component density product applications. Before adapting the minimum land pattern variations the user should perform qualication
testing based on the conditions outlined in IPC Standard 7351 (IPC–7351).

with wave (single or dual), convection, IR or vapor phase reow
techniques. Preheating of these components is recommended
to avoid extreme thermal stress. KEMET's recommended
prole conditions for convection and IR reow reect the prole
conditions of the IPC/J–STD–020D standard for moisture
sensitivity testing. The devices can safely withstand a maximum
of three reow passes at these conditions.
Note that although the X/7343–43 case size can withstand wave
soldering, the tall prole (4.3 mm maximum) dictates care in wave
process development.
Hand soldering should be performed with care due to the difculty
in process control. If performed, care should be taken to avoid
contact of the soldering iron to the molded case. The iron should
be used to heat the solder pad, applying solder between the pad
and the termination, until reow occurs. Once reow occurs, the
iron should be removed immediately. "Wiping" the edges of a chip
and heating the top surface is not recommended.
During typical reow operations, a slight darkening of the gold-
colored epoxy may be observed. This slight darkening is normal
and is not harmful to the product. Marking permanency is not
affected by this change.
