Note :
1. After charging a capacitor at the rated voltage of 5.5V for an hour, the capacitance is
calculated by the following formula, measuring the time of duration,
∆T (Sec.) from
4V down to 3V when constant current dischage at i (mA) = 0.02 × nominal capacitance
is carried out.
Capacitance (mF) = i ×
∆T
2. Current value (20°C) after applying the rated voltage of 5.5V for an hour.
3. Voltage value maintained after the capacitor is subjected to 1 hour voltage application
at 5V and then left at room temperature (lower than 25°C) for 24 hours.
