*1 The waveform of the maximum DC applied voltage is flat.
When a ripple voltage as from a rectifier source is applied, make
sure that the peak voltage is within the Vdcm rating.
The AC applied voltage (50/60Hz) is a sine waveform.
When waveform distortion is extensive, make sure that the peak
voltage is less than 2 times the Vacm rating.
2
* Energy Wtm
Transient energy rating are given in the Wtm column in Joules (Wattsecond). The rating is the maximum allowable energy of a single 2ms
square-waveform impulse current continuously applied.
Energy ratings are based on a shift of Vnom of less than ±10% of
the initial value.
*3 Transient peak current (Itm)
The peak current rating, Itm, is based on 8/20µs test impulse wave
form. This peak current is the maximum peak current at which the
nominal varistor voltage shift dose not exceed ±10% when the test
impulse is applied twice at a 5 minute interval.
4
* Nominal varistor voltage: Vnom
Indicates the varistor terminal voltage measured with 1mA DC
applied. 05A type 0.1mA DC
*5 Maximum clamping voltage: Vc
Indicates the peak terminal voltage measured with 8/20µs impulse
current applied.
