<Fig. 3> Allowable Voltage (Sine Wave Voltage) - Frequency Characteristics (At Ambient Temperature of 85°C or less)
Because of the influence of harmonics, when the applied
to the allowable voltage for a sine wave whose fundamental
voltage is a rectangular wave or pulse wave voltage (instead
frequency is twice as large as that of the rectangular wave or
of a sine wave voltage), the heat generated by the capacitor
pulse wave. This allowable voltage, however, varies
is higher than the value obtained by application of the sine
depending on the voltage and current waveforms.

Therefore, you are requested to make sure that the self-
Roughly calculated for reference, the allowable voltage for a
heating temperature is not higher than the value specified in
rectangular wave or pulse wave corresponds approximately
