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
eciency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qualication
testingwithmaximumoperationaltemperaturelifeup
to125ºCand150ºCrespectively.Thesecapacitorsare
manufacturedinanISOTS16949certiedplantsandare
subjectedtoPPAP/PSW,aswellaschangecontrol.
