6-2-2. Electrostatic Capacity (for reference)
1) Follow next measuring method in the circuit shown in Fig. 6-2-1.
2) Set DC voltage (E) as listed in Table 6-2.
3) Turn SW toward 1 for charging. Charge and impress listed voltage (E) for listed
time (T) in Table 6-2 through protective resistance (R).
4) After having impressed the voltage for listed time, then turn SW toward 2 for
discharging by listed discharging current (I) in Table 6-2 through constant-current
load device.
5) Measure the time while the tab-voltage of product (capacitor) changes from listed
starting voltage (V1) to ending voltage (V2) in Table 6-2 (Td=T2-T1). Then
calculate capacity (C) by following formula. Please refer to Fig. 6-2-2.

Measure by alternating method with Frequency 1kHz.
6-4. Charging Current (for reference)
After test sample is charged in the circuit shown in Fig.6-4 by listed voltage (E) and
listed protective resistance (R) for listed time in Table 6-4, measure the voltage (V)
between tabs of protective resistance (R).
Then calculate charging current (I) by following formula.
