2. Measurement of Capacitance
1. Measure capacitance with the voltage and frequency
specified in the product specifications.
1-1. The output voltage of the measuring equipment may
decrease occasionally when capacitance is high.
Please confirm whether a prescribed measured
voltage is impressed to the capacitor.
1-2. The capacitance values of high dielectric constant
type capacitors change depending on the AC voltage
applied. Please consider the AC voltage
characteristics when selecting a capacitor to be used
in an AC circuit.

3. Applied Voltage
1. Do not apply a voltage to the capacitor that exceeds the
rated voltage as called out in the specifications.
1-1. Applied voltage between the terminals of a capacitor
shall be less than or equal to the rated voltage.
(1) When AC voltage is superimposed on DC voltage,
the zero-to-peak voltage shall not exceed the
rated DC voltage.
When AC voltage or pulse voltage is applied, the
peak-to-peak voltage shall not exceed the rated
DC voltage.
(2) Abnormal voltages (surge voltage, static
electricity, pulse voltage, etc.) shall not exceed
the rated DC voltage.

(E: Maximum possible applied voltage.)
1-2. Influence of over voltage
Over voltage that is applied to the capacitor may
result in an electrical short circuit caused by the
breakdown of the internal dielectric layers.
The time duration until breakdown depends on the
applied voltage and the ambient temperature.
2. Use a safety standard certified capacitor in a power
supply input circuit (AC filter), as it is also necessary to
consider the withstand voltage and impulse withstand
voltage defined for each device.
