KEMET Organic Capacitor (KO-CAP
®
) – Industrial
Tantalum Stack Polymer (TSP) Electrolytic Stack, 3 – 63 VDC
Overview
The KEMET Tantalum Stack Polymer (TSP) Electrolytic
is designed to provide the highest capacitance/voltage
ratings in a surface mount configuration. KEMET's T540
COTS Polymer Electrolytic for High Reliabilty Applications
capacitors are utilized in stacks of 2, 3, 4 and 6 components
to achieve a broad range of capacitance and voltage ratings.
The T540 COTS offers component level surge current testing
options and standard and low ESR options. As with other
KEMET KO-CAPs, this series may be operated at steady
state voltages up to 90% of rated voltage for part types
with rated voltages of greater or equal to 10 volts and up
to 80% of rated voltage for part types greater than 10 volts.
Stacking configurations allow for custom capacitance/
voltage solutions and very low ESR options.
The TSP series is the first polymer electrolytic capacitor
available with failure rate options as defined by KEMET's
Polymer Electrolytic Reliability Assessment method (PERA).
The PERA method utilizes accelerated conditions (voltage
and temperature) applied to board mounted samples to
assess long term device reliability.The failure rates available
are B (0.1%/Khrs.), C (0.01%/Khrs.) and D (0.001%/Khrs).
The PERA method was developed based on over ten (10)
years of research and is described in numerous papers
available on www.kemet.com.
Note: Custom stacking solutions are also available with other KEMET
Polymer Electrolytic Surface Mount products. Please contact KEMET Sales
for availability.

Reliability
KO-CAP capacitors have an average failure rate of 0.5 %/1,000 hours at category voltage, U
C
, and category temperature, T
C
.
These capacitors are qualified using industry test standards at U
C
and T
C
. The minimum test time (1,000 or 2,000 hours) is
dependent on the product series.
The actual life expectancy of KO-CAP capacitors increases when application voltage, U
A
, and application temperature, T
A
, are
lower than U
C
and T
C
. As a general guideline, when U
A
< 0.9 * U
C
and T
A
< 85°C, the life expectancy will typically exceed the
useful lifetime of most hardware (> 10 years).
The lifetime of a KO-CAP capacitor at a specific application voltage and temperature can be modeled using the equations
below. A failure is defined as passing enough current to blow a 1-Amp fuse. The calculation is an estimation based on
empirical results and is not a guarantee.
