196 DLC www.vishay.com Vishay BCcomponents DISCHARGE CHARACTERISTICS Backup 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). MGA695 10 5 Backup time (s) Figure 10 shows the backup time when a 196 DLC capacitor is discharged by a constant resistance (charging time 24 h).
