Capacitance (Discharge System)

In the diagram below, charging is performed for a duration of 30 minutes, once the voltage of the condensor terminal

reaches 5.5 V.

Then, use a constant current load device and measure the time for the terminal voltage to drop from 3.0 to 2.5 V upon

discharge at 0.22 mA for 0.22 F, for example, and calculate the static capacitance according to the equation shown below.

Note: The current value is 1 mA discharged per 1F.

(1) Capacitance ( Charge System )

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

measurement, short between both pins of the capacitor for 30 minutes or more to let it discharge. In addition, follow the indication

of the product when determining the polarity of the capacitor during charging.
