Supercapacitors – FC Series

Measurement Conditions

Capacitance (Charge System)

Capacitance is calculated from expression (9) by measuring the charge time constant (τ) of the capacitor (C). Prior to measurement, the

capacitor is discharged by shorting both pins of the device for at least 30 minutes. In addition, use the polarity indicator on the device to

determine correct orientation of capacitor for charging.

Eo:

3.0 (V) Product with maximum operating voltage of 3.5 V

5.0 (V) Product with maximum operating voltage of 5.5 V

6.0 (V) Product with maximum operating voltage of 6.5 V

10.0 (V) Product with maximum operating voltage of 11 V

12.0 (V) Product with maximum operating voltage of 12 V

τ:

Time from start of charging until Vc becomes 0.632 Eo (V) (seconds)

Rc:

See table below (Ω).
