KEMET Organic Capacitor (KO-CAP
®
) – Automotive Grade
T591, T598 & T599 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 an improved
capacitance retention at high frequencies. KO-CAP
combines the low ESR of the 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/T599 High Humidity and High Temperature
Polymer Electrolytic capacitors deliver 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, T599) at 85°C/85% RH rated voltage and to
fully comply with the AEC-Q200 qualification testing with
maximum operational temperature life up to 125°C and 150°C
respectively. These capacitors are manufactured in an ISO TS
16949 certified plant and are subjected to PPAP/PSW, as well
as change control.

KEMET Organic Capacitor (KO-CAP

T591, T598 & T599 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 hours 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.
