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 Figs 9 and 10 (charging time 24 hours).

Figure 11 shows the backup time when a 196 DLC capacitor is discharged by a constant resistance (charging time 24 hours). The horizontal axis shows the initial value of discharge current if 5 V is connected to the capacitor via a fixed series resistor. EXAMPLE: 1 A CORRESPONDS TO 5 M AND 0.1 A CORRESPONDS TO 50 M The vertical axis shows that period of time during which the voltage drops from 5 to 2 V.
