DISCHARGE CHARACTERISTICS

Backup time of 196 HVC 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 Fig. 20 to Fig. 23 (charging time

 24 h and CC-CV

charging according to table 3).
