Environmental Compliance
Asanenvironmentallyconsciouscompany,KEMETisworkingcontinuouslywithimprovementsconcerningtheenvironmental
effectsofbothourcapacitorsandtheirproduction.InEurope(RoHSDirective)andinsomeothergeographicalareaslike
China,legislationhasbeenputinplacetopreventtheuseofsomehazardousmaterials,suchaslead(Pb),inelectronic
equipment.Allproductsinthiscatalogareproducedtohelpourcustomers’obligationstoguaranteetheirproductsandfulll
theselegislativerequirements.Theonlymaterialofconcerninourproductshasbeenlead(Pb),whichhasbeenremoved
fromalldesignstofullltherequirementofcontaininglessthan0.1%ofleadinanyhomogeneousmaterial.KEMETwill
closelyfollowanychangesinlegislationworldwideandmakesanynecessarychangesinitsproducts,wheneverneeded.
Somecustomersegmentssuchasmedical,militaryandautomotiveelectronicsmaystillrequiretheuseofleadinelectrode

for RoHS compatible capacitors.

If a capacitor has been stored for more than 18 months under these conditions and it shows increased leakage current,
then a treatment by voltage application is recommended.

Inoperation,electrolyticcapacitorswillalwaysconductaleakagecurrentwhichcauseselectrolysis.Theoxygenproducedby
electrolysiswillregeneratethedielectriclayerbut,atthesametime,thehydrogenreleasedmaycausetheinternalpressure

Installing
• Ageneralprincipleisthatlower-usetemperaturesresultinalonger,usefullifeofthecapacitor.Forthisreason,itshould
beensuredthatelectrolyticcapacitorsareplacedawayfromheat-emittingcomponents.Adequatespaceshouldbe
allowedbetweencomponentsforcoolingairtocirculate,particularlywhenhighripplecurrentloadsareapplied.Inany
case,themaximumcategorytemperaturemustnotbeexceeded.
• Donotdeformthecaseofcapacitorsorusecapacitorswithadeformedcase.
• Verifythattheconnectionsofthecapacitorsareabletoinsertontheboardwithoutexcessivemechanicalforce.
• Ifthecapacitorsrequiremountingthroughadditionalmeans,therecommendedmountingaccessoriesshallbeused.
• Verifythecorrectpolarizationofthecapacitorontheboard.
• Verifythatthespacearoundthepressurereliefdeviceisaccordingtothefollowingguideline:
Case Diameter Space Around Safety Vent
≤16mm > 2 mm
>16to≤40mm > 3 mm
> 40 mm > 5 mm
Itisrecommendedthatcapacitorsalwaysbemountedwiththesafetydeviceuppermostorintheupperpartofthecapacitor.
• Ifthecapacitorsarestoredforalongtime,theleakagecurrentmustbeveried.Iftheleakagecurrentissuperiortothe
valuelistedinthiscatalog,thecapacitorsmustbereformed.Inthiscase,theycanbereformedbyapplicationoftherated

• Inthecaseofcapacitorsconnectedinseries,asuitablevoltagesharingmustbeused.

Application and Operation Guidelines
Electrical Ratings:
Capacitance (ESC)
Simplifi ed equivalent circuit diagram of an electrolytic capacitor
Thecapacitivecomponentoftheequivalentseriescircuit(EquivalentSeriesCapacitanceESC)isdeterminedbyapplyingan
alternatevoltageof≤0.5Vatafrequencyof120or100Hzand20°C(IEC384-1,384-4).
Temperature Dependence of the Capacitance
Capacitance of an electrolytic capacitor depends upon
temperature:withdecreasingtemperaturetheviscosity
oftheelectrolyteincreases,therebyreducingits
conductivity.
Capacitance will decrease if temperature decreases.
Furthermore,temperaturedriftscausearmature
dilatationand,therefore,capacitancechanges(upto20%
dependingontheseriesconsidered,from0to80°C).This
phenomenonismoreevidentforelectrolyticcapacitors
thanforothertypes.
Frequency Dependence of the Capacitance
Effectivecapacitancevalueisderivedfromtheimpedance
curve,aslongasimpedanceisstillintherangewherethe
capacitance component is dominant.

Reisthemosttemperature-dependentcomponentofanelectrolyticcapacitorequivalentcircuit.Electrolyteresistivitywill
decrease if temperature rises.
Inordertoobtainalowimpedancevaluethroughoutthetemperaturerange,Re must be as little as possible. However, Re
valuesthataretoolowindicateaveryaggressiveelectrolyte,resultinginashorterlifeoftheelectrolyticcapacitorathigh
temperatures.Acompromisemustbereached.
Leakage Current (LC)
Duetothealuminumoxidelayerthatservesasadielectric,asmallcurrentwillcontinuetoflowevenafteraDCvoltagehas
beenappliedforlongperiods.Thiscurrentiscalledleakagecurrent.
Ahighleakagecurrentflowsafterapplyingvoltagetothecapacitorthendecreasesinafewminutes,e.g.,afterprolonged
storagewithoutanyappliedvoltage.Inthecourseofcontinuousoperation,theleakagecurrentwilldecreaseandreachan
almost constant value.
Afteravoltage-freestoragetheoxidelayermaydeteriorate,especiallyathightemperature.Sincetherearenoleakage
currentstotransportoxygenionstotheanode,theoxidelayerisnotregenerated.Theresultisthatahigherthannormal

Leakage Current (LC) cont’d
Astheoxidelayerisregeneratedinuse,theleakagecurrentwill
gradually decrease to its normal level.
Therelationshipbetweentheleakagecurrentandvoltageapplied
atconstanttemperaturecanbeshownschematicallyasfollows:
Where:
VF = Forming voltage
Ifthislevelisexceeded,alargequantityofheatandgaswillbe
generatedandthecapacitorcouldbedamaged.
VR = Rated Voltage
Thislevelrepresentsthetopofthelinearpartofthecurve.
VS = Surge voltage
ThisliesbetweenVR and VF.ThecapacitorcanbesubjectedtoVSforshortperiodsonly.
Electrolyticcapacitorsaresubjectedtoareformingprocessbeforeacceptancetesting.Thepurposeofthispreconditioning
istoensurethatthesameinitialconditionsaremaintainedwhencomparingdifferentproducts.
Ripple Current (RC)
Themaximumripplecurrentvaluedependson:
• Ambient temperature
•Surfaceareaofthecapacitor(heatdissipationarea)
tanδorESR
• Frequency
Thecapacitor’slifedependsonthethermalstress.
Frequency Dependence of the Ripple Current
ESRand,thus,thetanδdependonthefrequencyoftheappliedvoltage.Thisindicatesthattheallowedripplecurrentisalso
afunctionofthefrequency.
Temperature Dependence of the Ripple Current
Thedatasheetspeciesmaximumripplecurrentattheuppercategorytemperatureforeachcapacitor.

Where:

Themanufacturingprocessbeginswiththeanodefoilbeing
electrochemicallyetchedtoincreasethesurfaceareaandthen
“formed”toproducethealuminumoxidelayer.Boththeanodeand
cathodefoilsaretheninterleavedwithabsorbentpaperandwound
intoacylinder.Duringthewindingprocess,aluminumtabsare
attachedtoeachfoiltoprovidetheelectricalcontact.
Thedeck,completewithterminals,isattachedtothetabsandthen
foldeddowntorestontopofthewinding.Thecompletewinding
isimpregnatedwithelectrolytebeforebeinghousedinasuitable
container,usuallyanaluminumcan,andsealed.Throughoutthe
process,allmaterialsinsidethehousingmustbemaintainedatthe
highestpurityandbecompatiblewiththeelectrolyte.
Eachcapacitorisagedandtestedbeforebeingsleevedandpacked.
Thepurposeofagingistorepairanydamageintheoxidelayer
andthusreducetheleakagecurrenttoaverylowlevel.Agingis
normallycarriedoutattheratedtemperatureofthecapacitorand
isaccomplishedbyapplyingvoltagetothedevicewhilecarefully
controllingthesupplycurrent.Theprocessmaytakeseveralhoursto
complete.
Damagetotheoxidelayercanoccurduetovarietyofreasons:
•Slittingoftheanodefoilafterforming
•Attachingthetabstotheanodefoil
•Minormechanicaldamagecausedduringwinding
Asamplefromeachbatchistakenbythequalitydepartmentafter
completionoftheproductionprocess.Thissamplesizeiscontrolled
bytheuseofrecognizedsamplingtablesdenedinBS6001.
Thefollowingtestsareappliedandmaybevariedattherequest
ofthecustomer.Inthiscasethebatch,orspecialprocedure,will
