Axial Leaded Multilayer Ceramic Capacitors
Aximax, 400, Conformally Coated, X7R Dielectric, 25 – 250 VDC (Automotive Grade)
Storage & Handling
The un-mounted storage life of a leaded ceramic capacitor is dependent upon storage and atmospheric conditions as
wellaspackagingmaterials.Whiletheceramicchipsenvelopedundertheepoxycoatingthemselvesarequiterobust
inmostenvironments,solderabilityofthewireleadonthenalepoxy-coatedproductwillbedegradedbyexposureto
hightemperatures,highhumidity,corrosiveatmospheres,andlongtermstorage.Inaddition,packagingmaterialswillbe
degradedbyhightemperatureandexposuretodirectsunlight–reelsmaysoftenorwarp,andtapepeelforcemayincrease.
KEMET recommends storing the un-mounted capacitors in their original packaging, in a location away from direct sunlight,
andwherethetemperatureandrelativehumiditydonotexceed40degreescentigradeand70%respectively.Foroptimum
solderability,capacitorstockshouldbeusedpromptly,preferablywithin18monthsofreceipt.Forapplicationsrequiring
pre-tinningofcomponents,storagelifemaybeextendedifsolderabilityisveried.Beforecleaning,bondingormoldingthese
devices,itisimportanttoverifythatyourprocessdoesnotaffectproductqualityandperformance.KEMETrecommends
testingandevaluatingtheperformanceofacleaned,bondedormoldedproductpriortoimplementingand/orqualifyingany
of these processes.
