THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENTARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT CHARACTERISTICSB ackup time of 196 DLC series Capacitors depends on minimum memory holding voltage and discharge current (corresponding with the current consumption of the load). For minimum backup times of standard and vertical miniaturized series see Figures 8 and 9 (charging time 24 h).

10 Fig. 8 - Typical backup time as a function of discharge currentFig. 9 - Typical backup time as a function of discharge currentFigure 10 shows the backup time when a 196 DLC capacitor is discharged by a constant resistance (charging time 24 h).The horizontal axis shows the initial value of discharge current if 5 V is connected to the capacitor via a fixed series : 1 A corresponds to 5 M and A corresponds to 50 M The vertical axis shows that period of time during which the voltage drops from 5 V to 2 10 - Typical backup time as a functionof initial discharge current10 MGA695110510410310210 Backuptime(s)Discharge current (mA)10-310-210-154321 Curve 1: F, VCurve 2: F, VCurve 3: F, VCurve 4: F, VCurve 5.
