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. ## Benefits - Ultra low ESR - Full compliance with AEC-Q200 qualification test plan (T597 FD 125°C, T598 125°C, T599 150°C) - Qualification plan based on AEC–Q200 with 85°C/85% - RH load specification limited to 500 hours (T591) - Extended endurance test qualification for T598/T599 (VR < 16 V) , up to 2,000 hours 125°C - Dedicated H / T termination and Surge current testing options (T598) for Defense and Aerospace Segment - TS 16949 certified plants 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. ## Applications Typical applications include decoupling and filtering in a variety of market segments, with special emphasis in automotive applications such as infotainment, ADAS, chassis and safety, as well as powertrain, where harsh conditions, such as high humidity and temperature, are a concern. The T598 with H termination and S and W surge current Upscreen options are suitable low orbit satellites in New Space Applications. - Subject to PPAP/PSW and change control - Meets or exceeds EIA standard 535BAAC - Tape & Reel standard packaging per EIA 481 - Halogen-free epoxy and RoHS compliant T2073_T59X (2025-11-03) 1 | YAGEOGroup.com **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 ## K-SIM For a detailed analysis of specific part numbers, please visit ksim3.kemet.com to access KEMET’s K-SIM software.

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. **==> picture [441 x 262] intentionally omitted <==** **----- Start of picture text -----**

_For T598 Up-screen with H termination, surge current option S and W used in low orbit satellites, a 50% derate voltage is recommended_ ## Recommended Application Voltage 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. |Voltage

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. |Case Code|EIA

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. _I(max) = √Pmax/R E(max) = Z √Pmax/R_ _I = rms ripple current (amperes) E = rms ripple voltage (volts) Pmax = maximum power dissipation (watts) R = ESR at specified frequency (ohms) Z = Impedance at specified frequency (ohms)_ ||Temperature Compensation Multipliers

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. **==> picture [542 x 44] intentionally omitted <==** **----- Start of picture text -----**

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. 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. **==> picture [269 x 35] intentionally omitted <==** **----- Start of picture text -----**

## 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.
