ALC12 85°coperational dataOperational LifetimePlease see separate BHC applicationnotes TD003 for calculating operationallife expectancy under customer specificconditions.ReliabilityThe failure rate is derived from our periodictest results. The failure rate (λ R) is thereforeonly given at test temperature for life tests.An estimation is also given at 40°C. Theexpected failure rate for this capacitor rangeis based on our periodic test results forcapacitors with structural similarity. Failurerate is frequently quoted in FIT (Failures InTime) where 1 FIT = 1 x 10 -9 failures perhour.T aFailure rate per hour85°C 250 FIT40°C 12 FITFailure rate per hour for catastrophic plusparametric failures.Mechanical dataMounting positionThe capacitor can be mounted upright orinclined to a horizontal position.Vibration10Hz to 500Hz at 0.75mm or 10g for 3x2hrsduration. 10Hz to 55Hz at 0.35mm or 5gfor 3x0.5hrs duration (45/50mm diametercans).Insulating resistance> 100 Mohms at 100V d.c., across insulatingsleeve.Voltage Proof> 2500V d.c., across insulating sleeve.Safety ventA safety vent for over pressure is featuredon either the base (opposing end to theterminals) or on the the side of the can. Thisis in the form of a grooved section on thesurface of the can which is a weakened areaand is designed to relieve build up of internalpressure due to over stress or catastrophicfailure.KEMET Electrolytic Capacitors105
