Environmental Compliance
Asaleadingglobalsupplierofelectroniccomponentsandanenvironmentallyconsciouscompany,KEMETcontinually
aspirestoimprovetheenvironmentaleffectsofourmanufacturingprocessesandournishedelectroniccomponents.
InEurope(RoHSDirective)andinsomeothergeographicalareassuchasChina(ChinaRoHS),legislationhasbeenenacted
topreventorotherwiselimittheuseofcertainhazardousmaterials,includinglead(Pb),inelectronicequipment.KEMET
monitorslegislationgloballytoensurecomplianceandendeavorstoadjustourmanufacturingprocessesand/orelectronic
componentsasmayberequiredbyapplicablelaw.
Formilitary,medical,automotive,andsomecommercialapplications,theuseoflead(Pb)intheterminationisnecessary
and/orrequiredbydesign.KEMETiscommittedtocommunicatingRoHScompliancetoourcustomers.Informationrelated
toRoHScompliancewillbeprovidedindatasheetsandusingspecicidentiersonthepackaginglabels.
AllKEMETpowerlmcapacitorsareRoHScompliant.
Materials & Environment
The selection of raw materials that KEMET uses for the production of its electronic components is the result of extensive
experience.KEMETdirectsspecicattentiontowardenvironmentalprotection.KEMETselectsitssuppliersaccordingto
ISO9001standardsandperformsstatisticalanalysesonrawmaterialsbeforeacceptanceforuseinmanufacturingour
electroniccomponents.Allmaterialsare,tothebestofKEMET’sknowledge,non-toxicandfreefromcadmium;mercury;
chromeandcompounds;polychlorinetriphenyl(PCB);bromideandchlorinedioxinsbromurateclorurate;CFCandHCFC;
andasbestos.
Dissipation Factor
Dissipationfactorisacomplexfunctioninvolvedwithcapacitorineciency.Thetgδmayvaryupanddownwithincreased
temperature. For more information, refer to Performance Characteristics.
Sealing
Hermetically Sealed Capacitors
As the temperature increases, the pressure inside the capacitor increases. If the internal pressure is high enough, it can
causeabreachinthecapacitor.Suchabreachcanresultinleakage,impregnation,llinguid,ormoisturesusceptibility.
Barometric Pressure
Thealtitudeatwhichhermeticallysealedcapacitorsareoperatedcontrolsthecapacitor'svoltagerating.Asthebarometric
pressuredecreases,thesusceptibilitytoterminalarc-overincreases.Non-hermeticcapacitorscanbeaffectedbyinternal
stressesduetopressurechanges.Theseeffectscanbeintheformofcapacitancechanges,dielectricarc-over,and/orlow
insulationresistance.Altitudecanalsoaffectheattransfer.Heatthatisgeneratedinanoperationcannotbedissipated
properly, and high RI

losses and eventual failure can result.
