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 efficiencyoftantalumintoasinglesurfacemountpackage.Unlike liquid electrolyte-based capacitors, KO-CAP has a very long operational life, and high ripple current capabilities.
The T522 Reduced Leakage Polymer Electrolytic design is basedontheT520KO-CAPseries.Developedspecificallyto meet the needs of leakage current sensitive applications, the T522 is well-suited for battery-based circuits. The T522 provides the lowest leakage values available in polymer electrolytic capacitors, with upper leakage limits that are up to 70% lower than comparable KO-CAP capacitors.
Typical applications include battery dependent applications such as handheld consumer electronics, global tracking systems,energyharvesting,wirelesssensors,andotherapplicationsthatseekhighcapacitance,lowprofile,safety,andlowpower consumption.
Environmental Compliance
RoHS Compliant (6/6) according to Directive 2002/95/EC when ordered with 100% Sn solder.

KO-CAP capacitors have an average failure rate of 0.5 %/1,000 hours at category voltage, UC, and category temperature, TC. ThesecapacitorsarequalifiedusingindustryteststandardsatUC and TC. The minimum test time (1,000 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,thelifeexpectancywilltypicallyexceedthe useful lifetime of most hardware (> 10 years).

Recommended Application VoltageKO-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 graphic above, for the maximum steady state 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 specifiedforreversevoltage.SeetheReverseVoltagesection 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.

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.Surgevoltagecapabilityisdemonstratedbyapplicationof1,000cyclesatrelevantvoltageat105ºCand125ºC.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).1 Height of these chips may create problems in wave soldering.2 Land pattern geometry is too small for silkscreen outline.

Please note that although the X/7343–43 case size can withstandwavesoldering,thetallprofile(4.3mmmaximum)dictates care in wave process development.
Hand soldering should be performed with care due to the difficultyinprocesscontrol.Ifperformed,careshouldbetaken 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 reflowoccurs.Oncereflowoccurs,theironshouldberemoved immediately. “Wiping” the edges of a chip and heating the top surface is not recommended.
