<Fig. 3 (continued)> Allowable Voltage (Sine Wave Voltage) -
Frequency Characteristics
(At Ambient Temperature of 85°C or less)
Because of the influence of harmonics, when the applied
voltage is a rectangular wave or pulse wave voltage
(instead of a sine wave voltage), the heat generated by
the capacitor is higher than the value obtained by
application of the sine wave with the same fundamental
frequency.
Roughly calculated for reference, the allowable voltage
for a rectangular wave or pulse wave corresponds
approximately to the allowable voltage for a sine wave
whose fundamental frequency is twice as large as that of
the rectangular wave or pulse wave.
This allowable voltage, however, varies depending on the
voltage and current waveforms.
Therefore, you are requested to make sure that the self-
heating temperature is not higher than the value specified
in Table 1.
