KEMET Organic Capacitor (KO-CAP
®
) – Industrial
Tantalum Stack Polymer (TSP) Electrolytic Stack, 3 – 63 VDC
Overview
The KEMET Tantalum Stack Polymer (TSP) Electrolytic
Capacitor is designed to provide the highest CV
(capacitance/voltage) ratings in a surface mount
configuration. All of KEMET's Polymer Electrolytic Solutions
are available in a stack configuration.The only exceptions
are the facedown series (T523,T527,T528, and T529).
These capacitors are utilized in stacks of 2,3,4, and 6
components to achieve a broad range of capacitance,
ESR, and voltage ratings. The TSP series may be operated
at steady state voltages up to 90% of rated voltage for
part types with rated voltage less than 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 when utilizing KEMET's
T540 and T541 Series. The failure rate is determined by
utilizing accelerated conditions (voltage and temperature)
applied to board mounted samples to assess long term
device reliability. The failure rates available are B (0.1% per
1,000 hours), C (0.01% per 1,000 hours), and D (0.001% per
1,000 hours). This 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.

KEMET Organic Capacitor (KO-CAP

Tantalum Stack Polymer (TSP) Electrolytic Stack, 3 – 63 VDC
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.
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.
