Notes :

①The 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 √2times the Vacm.

②Energy : 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.

③Transient peak current (ltm)

The peak current rating. ltm. 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 twice at 5 mimutes intervals.

④Nominal 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.

⑤Maximum 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℃
