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 µA CORRESPONDS TO 5 MΩ AND 0.1 µA
CORRESPONDS TO 50 MΩ

The vertical axis shows that period of time during which the
voltage drops from 5 to 2 V.
