CLG04P050L28 Datasheet, PDF (14/26 Pages) List of Unclassifed Manufacturers – Super Capacitors To Improve Power Performance.

Measuring Method of Characteristics
Capacitance
1) Charge the capacitor at constant current to nominal voltage(V1) and hold
the nominal voltage for 10 minutes.
2) Discharge the capacitor with constant current (A) to the voltage of (V2 )
while measure discharge time (T).
3) Calculate capacitance using following formula
Equivalent Series ^{1) Measure ESR by HIOKI Model 3560 AC Low Ohmmeter}
Resistance
(ESR @1Khz)
Leakage Current
1) Apply Nominal voltage to the capacitor.
2) Measure Vr after 12±1 hours.
3) Calculate current using following formula.
Supercapacitor should be shorted before each measurement as follows:
Capacitance:60 min., ESR: 15 min., LC: 12 hours
