Notes :
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
that the peak voltage is less than times the Vacm.
Energy : Wtm
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.
Transient peak current(Itm)
The peak current rating. Itm. of varistor is based on an 8/20
test impulse waveshape. This peak current is the
maximum peak current in which the nominal varistor
voltage shift does not exceed 10% when the test impulse
is applied once at 5 mimutes intervals.
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.
Maximum clamping voltage : Vc
Indicates the peak teminal voltage measured with an 8/20
impulse current applied.
Operating ambient temperature : -40 to +80
Storage temperature : -40 to +125
UL and CSA recognized(UL 1449, UL 497B or UL 1414, CSA)
SVC varistors have been tested by Underwiter’s
Laboratories, Inc. and Canadian Standards Association
UL File No. E97754, E151195, E154171.
CSA File No. LR78923.
