FAQ
Why the is derating of high frequency voltage necessary?
The high frequency voltage is to be limited by the allowable current value for high frequency as mentioned above. However, this voltage refers strictly to the AC components. In case when DC voltage is overlapped on it, the peak voltage should never exceed the DC rated voltage.
Moreover, in case of the waveforms different from the sine wave, it is also necessary to check and confirm whether the following conditions are satisfied.
(1) Current conditions are satisfied (less than the allowable current).
(2) In case when the pulse rated voltage is specified, Up-p voltage is lower than the rated voltage.
