Supercapacitors – FT 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).
