Capacitance (Discharge System:3.5V)

In the diagram below, charging is performed for a duration of 30 minutes, once the voltage of the capacitor terminal reaches 3.5V.

Then, use a constant current load device and measure the time for the terminal voltage to drop from 1.8 to 1.5V upon

discharge at 1 mA per 1F, and calculate the static capacitance according to the equation shown below.

Capacitance (Discharge System:HVseries)

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

Max. operating voltage.

Then, use a constant current load device and measure the time for the terminal voltage to drop from 2.0 to 1.5V upon discharge

at 1 mA per 1F, and calculate the static capacitance according to the equation shown below.

Equivalent series resistance (ESR)

ESR shall be calculated from the equation below.

Current (at 30 minutes after charging)

Current shall be calculated from the equation below.

Prior to measurement, both lead terminals must be short-circuited for a minimum of 30 minutes.

The lead terminal connected to the metal can case is connected to the negative side of the power supply.
