Notes :
① The waveform of the maximum DC applied voltage is flat.
When a ripple voltage as from a rectifier source is supplied
make sure that the peak voltage is kept under th Vdcm An
AC applied voltage(50/60Hz) form a since waveshape.
When the distortion in the waveform is extensive make sure
is applied once at 5 mimutes intervals.
④ Nominal varistor voltage : Vnom
Indicates the varistor terminal voltage measured with a 1mA
DC applied. -0.1mA DC in the case of the 0.5A and 05B
series.
that the peak voltage is less than
times the Vacm.
② Energy : Wtm
⑤ Maximum clamping voltage : Vc
Transient energy ratings are given in the Wtm column of the
specifications in Joules(watt-second). The rating is the
maximum allowable energy for a single impulse of 2ms
square-waveform current with continuous voltage applied.
Energy ratings are based on a shift of Vnom of less than
±10% of initial value.
Indicates the peak teminal voltage measured with an 8/20㎲
impulse current applied.
