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.
