Performance The following specications will be satised when the capacitor is restored to 20°C:
CapacitanceChange Within±20%oftheinitialvalue
Dissipation Factor Doesnotexceed200%ofthespeciedvalue
Leakage Current Doesnotexceedspeciedvalue
Shelf Life
Thecapacitance,ESRandimpedanceofacapacitorwillnotchangesignicantlyafterextendedstorageperiods,however,
theleakagecurrentwillveryslowlyincrease.
KEMET'sEaluminumelectrolyticcapacitorsshouldnotbestoredinhightemperaturesorwherethereisahighlevelof
humidity.ThesuitablestorageconditionforKEMET'sEaluminumelectrolyticcapacitorsis+5to+35°Candlessthan75%
inrelativehumidity.KEMET'sEaluminumelectrolyticcapacitorsshouldnotbestoredindampconditionssuchaswater,
saltwatersprayoroilspray.KEMET'sEaluminumelectrolyticcapacitorsshouldnotbestoredinanenvironmentfullof
hazardousgas(hydrogensulphide,sulphurousacidgas,nitrousacid,chlorinegas,ammonium,etc.)KEMET'sEaluminum
electrolyticcapacitorsshouldnotbestoredunderexposuretoozone,ultravioletraysorradiation.
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.
Re-Age (Reforming) Procedure
Applytheratedvoltagetothecapacitoratroomtemperatureforaperiodofonehour,oruntiltheleakagecurrenthasfallen
toasteadyvaluebelowthespeciedlimit.Duringre-agingamaximumchargingcurrentoftwicethespeciedleakage
currentor5mA,whicheverisgreater,issuggested.
