KEMET Organic Capacitor (KO-CAP®) – Automotive Grade
T591, T598, T597, and T599 High Humidity and High
Temperature Automotive Grade Polymer Electrolytic,
2.5 – 75 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 a high ripple
current capabilities.
The T591/T597/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 125ºC and 150ºC respectively. These capacitors are
manufactured in an ISO TS 16949 certified plants and are
subjected to PPAP/PSW, as well as change control.

KEMET Organic Capacitor (KO-CAP ®) – Automotive Grade
T591, T598, T597, and T599 High Humidity and High Temperature Automotive Grade Polymer Electrolytic, 2.5 - 75 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 hours or 2,000
hours) is dependent on the product.
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.

KO-CAPs are solid state capacitors that demonstrate no wearout mechanism when operated within their recommended
guidelines. While the KO-CAP 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 voltage derating, according the graph above, for the maximum
steady state voltage.

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 Pmax of the device, the maximum allowable rms

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 course of normal operation and cannot be part of the application voltage.
Surge voltage capability is demonstrated by application of 1,000 cycles at operating temperature. 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 density 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.

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.

Storage
All KO-CAP capacitors are shipped in moisture barrier bags (MBBs) with desiccant and humidity indicator card (HIC).
These parts are classified as moisture sensitivity level 3 (MSL3) per IPC/JEDEC J-STD-020 and packaged per IPC/JEDEC
J–STD–033, MSL3 specifies a floor time of 168 H at 30°C maximum temperature and 60% relative humidity. Unused
capacitors should be sealed in a MBB with fresh desiccant.
Calculated shelf life in sealed bag:
– 12 months from bag seal date in a storage environment of < 40°C and humidity < 90% RH
– 24 months from bag seal date in a storage environment of < 30°C and humidity < 70% RH
If baking is required, refer to IPC/JEDEC J–STD–033 for bake procedure.

Note 5
1. The embossment hole location shall be measured from the sprocket hole controlling the location of the embossment. Dimensions of embossment
location and hole location shall be applied independent of each other.
2. The tape, with or without components, shall pass around R without damage (see Figure 4).
3. If S1 < 1.0 mm, there may not be enough area for cover tape to be properly applied (see EIA Standard 481–D, paragraph 4.3, section b).
4. B1 dimension is a reference dimension for tape feeder clearance only.
5. The cavity defined by A0, B0 and K0 shall surround the component with sufficient clearance that:
(a) the component does not protrude above the top surface of the carrier tape.
(b) the component can be removed from the cavity in a vertical direction without mechanical restriction, after the top cover tape has been removed.
(c) rotation of the component is limited to 20° maximum for 8 and 12 mm tapes (see Figure 2).
(d) lateral movement of the component is restricted to 0.5 mm maximum for 8 mm and 12 mm wide tape (see Figure 3).
(e) see Addendum in EIA Standard 481–D for standards relating to more precise taping requirements.

Packaging Information Performance Notes
1. Cover tape break force: 1.0 kg minimum.
2. Cover tape peel strength: The total peel strength of the cover tape from the carrier tape shall be:
Tape Width
Peel Strength
8 mm
0.1 to 1.0 newton (10 to 100 gf)
12 mm
0.1 to 1.3 newton (10 to 130 gf)
The direction of the pull shall be opposite the direction of the carrier tape travel. The pull angle of the cover tape shall be
165° to 180° from the plane of the carrier tape. During peeling, the carrier and/or cover tape shall be pulled at a velocity of
300 ±10 mm/minute.
3. Labeling: Bar code labeling (standard or custom) shall be on the side of the reel opposite the sprocket holes. Refer to EIA
Standards 556 and 624.
