The sinusoidal voltage is assumed as the normal operating condition. If a non-sinusoidal voltage is present, type selection should be based on multiplying the peak voltage by a factor of 0.707. 2. The voltage measured at 1 mA meets the requirements of "paragraph 4.3 of CECC specification 42000". 3. The maximum non-repetitive surge current is given for one impulse 8 x 20 s applied during the life of the component. Figures 2 and 3 give the derating for different numbers and longer a duration of pulses. 4. A current wave of 8 x 20 s (requirement of "paragraph B.2.10.1 of CECC specification 42000" ) is used as a standard for pulse current and clamping voltage ratings. 5. Energy is calculated by multiplying the peak voltage, peak current and transient duration for a standard impulse 10 x 1000 s (correction factor: x 1.4). 2002 Jan 25 3 BCcomponents Preliminary specification Surface mount multilayer varistors 2322 574 .....
