Test Methods
Specifications
Standard Test
Condition
Electrical measurements (initial/after tests) shall be conducted at
temperature of 5 to 35 ¡C, relative humidity of maximum 85 %
ÑÑ
Varistor Voltage
The voltage between two terminals with the specified measuring
current CmA DC applied is called Vc or VCmA. The measurement
shall be made as fast as possible to avoid heat affection.
Maximum Allowable
Voltage
The recommended maximum sinusoidal wave voltage (rms) or
the maximum DC voltage that can be applied continuously.
Clamping Voltage
Rated Power
The maximum voltage between two terminals with the specified
impulse current (8/20 µs).
The maximum power that can be applied within the specified
ambient temperature.
To meet the
specified value.
Maximum Energy
Maximum energy at less than ±10 % of varistor voltage change
when the standard impulse (2 ms) is applied one time.
Maximum
Peak Current
Maximum current at less than ±10 % of varistor voltage change
when impulse current (8/20 µs) is applied two times continuously
with the interval of 5 minutes.

The change of Vc shall be measured after the specified impulse
is applied 10000 times continuously with the interval of 10
seconds at room temperature.
