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.
