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.

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.

4. Type of Applied Voltage and Self-heating Temperature
1. Confirm the operating conditions to make sure that no large
current is flowing into the capacitor due to the continuous
application of an AC voltage or pulse voltage.
When a DC rated voltage product is used in an AC voltage
circuit or a pulse voltage circuit, the AC current or pulse
current will flow into the capacitor; therefore check the
self-heating condition.
Please confirm the surface temperature of the capacitor so
that the temperature remains within the upper limits of the
operating temperature, including the rise in temperature due
to self-heating. When the capacitor is used with a
high-frequency voltage or pulse voltage, heat may be
generated by dielectric loss.
<Applicable to Rated Voltage of less than 100VDC>
1-1. The load should be contained to the level such that
when measuring at atmospheric temperature of 25°C,
the product's self-heating remains below 20°C and the
surface temperature of the capacitor in the actual circuit
remains within the maximum operating temperature.
