Maximum working voltage determined by E = √PR , E should not exceed value listed in column above. Dielectric strength is rated the same as the maximum working voltage.
Peak pulse voltage is highly dependent on pulse waveform and resistance value. Voltage levels given indicate maximum levels for the series. These levels are not attainable for all values and pulse
waveforms. Consult factory for application assistance.
