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
• Ultra-low ESR
• Full compliance with AEC–Q200 Qualification Test Plan
(T598)

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, UC, and category temperature, TC.
These capacitors are qualified using industry test standards at UC and TC. 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, UA, and application temperature, TA,
are lower than UC and TC. As a general guideline, when UA < 0.9 * UC and TA < 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.

Recommended Application Voltage
KOCAP’s are solid state capacitors that demonstrate no wearout mechanism when operated within their recommended
guidelines. While the KOCAP can be operated at full rated voltage, most circuit designers seek a minimum level of
assurance in long term reliability which should be demonstrated with data.
A voltage derating can provide the desired level of demonstrated reliability based on industry accepted acceleration
models. Since most applications do require long term reliability, KEMET recommends that designers consider a 10% voltage
derating, according the graphic above, for the maximum steady state voltage.

KEMET Organic Capacitor (KO-CAP ®) – Automotive Grade
T591/T598 High Humidity/High Temperature Automotive Grade Polymer Electrolytic, 2.5 – 50 VDC
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
specified for reverse voltage. See the Reverse Voltage
section for allowable limits.
The maximum power dissipation by case size can be
determined using the table at right. The maximum power
dissipation rating stated in the table must be reduced
with increasing environmental operating temperatures.
Refer to the table below for temperature compensation
requirements.

Using the P max of the device, the maximum allowable rms
ripple current or voltage may be determined.
I(max) = √P max/R
E(max) = Z √P max/R
I = rms ripple current (amperes)
E = rms ripple voltage (volts)
P max = maximum power dissipation (watts)
R = ESR at specified frequency (ohms)

Surge Voltage
Surge voltage is the maximum voltage (peak value) which may be applied to the capacitor.
The surge voltage must not be applied for periodic charging and discharging in the course of normal operation and cannot
be part of the application voltage.
Surge voltage capability is demonstrated by application of 1,000cycles at relevant voltage at 105°C and 125°C.
The parts are charged through a 33 Ohm resistor for 30 seconds and then discharged though a 33 Ohm resistor for each
cycle.

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

Soldering Process
Please note that although the X/7343–43 case size can
withstand wave soldering, the tall profile (4.3 mm maximum)
dictates care in wave process development.
Hand soldering should be performed with care due to the
difficulty 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
reflow occurs. Once reflow occurs, the iron should be
removed immediately. “Wiping” the edges of a chip and
heating the top surface is not recommended.

Temperature
KEMET’s families of surface mount capacitors are
compatible with wave (single or dual), convection, IR,
or vapor phase reflow techniques. Preheating of these
components is recommended to avoid extreme thermal
stress. KEMET's recommended profile conditions for
convection and IR reflow reflect the profile conditions of the
IPC/J–STD–020D standard for moisture sensitivity testing.
The devices can safely withstand a maximum of three reflow
passes at these conditions.

All KO-Cap Series are shipped in moisture barrier bags (MBBs) with desiccant and humidity indicator card (HIC).
These parts are classified as MSL3 (Moisture Sensitivity Level 3) per IPC/JEDEC J-STD-020 and packaged per
IPC/JEDEC J–STD–033
MSL3 specifies a floor time of 168H at 30°C maximum temperature and 60% relative humidity
Unused capacitors should be sealed in a MBB with fresh desiccant.
