V
w(DC)
- Maximum Continuous DC Voltage with which the waveform is flat. When a ripple voltage is supplied as
from a rectifier source, make sure that the peak voltage is kept under the Vdcm.
V
w(ac)
- Maximum Continuous AC Voltage from a sine-wave shape. When the distortion in the waveform is
extensive, make sure that the peak voltage is less than
times the V
