KEMET Organic Capacitor (KO-CAP
®
) – Automotive Grade
T591/T598 High Humidity/High Temperature
Automotive Grade Polymer Electrolytic, 2.5 – 50 VDC
Overview
The KEMET Organic Capacitor (KO-CAP) is a solid
electrolytic capacitor with a conductive polymer cathode
capable of delivering very low ESR and improved
capacitance retention at high frequencies. KO-CAP
combines the low ESR of multilayer ceramic, the high
capacitance of aluminum electrolytic and the volumetric
efficiency of tantalum into a single surface mount package.
Unlike liquid electrolyte-based capacitors, KO-CAP
has a very long operational life and high ripple current
capabilities.
The T591/T598 High Humidity/High Temperature
Polymer Electrolytic series delivers higher capacitance
and ESR stability under harsh environmental conditions.
Enhancements to the design and selected material upgrades
were introduced to deliver 500 hours (T591) or 1,000 hours
(T598) at 85°C/85% RH rated voltage and to fully comply
with the AEC-Q200 QualificationTesting. These series are
manufactured in an ISO TS 16949 certified plant and are
subjected to PPAP/PSW and change control.
Benefits

Applications
Typical applications include decoupling and filtering in a variety of market segments, with special emphasis in automotive
applications such as infotainment and input/output in DC/DC converters, where harsh conditions such as high humidity and
temperature are a concern.
Environmental Compliance
RoHS Compliant (6/6) according to Directive 2002/95/EC when ordered with 100% Sn solder. Halogen-free.

KEMET Organic Capacitor (KO-CAP
®
) – Automotive Grade
T591/T598 High Humidity/High Temperature Automotive Grade Polymer Electrolytic, 2.5 – 50 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 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.
