Performance Characteristics
Characteristics
Standard Test
Condition
Test Methods
Electrical measurements (initial/after tests) shall be conducted at
temperature of 5 to 35 °C, relative humidity of maximum 85 %
The voltage between two terminals with the specified measuring
current 1mA DC applied is called V
1
or V
1mA
. The measurement
should be made as fast as possible to avoid heat effects.
The recommended maximum sinusoidal wave voltage (rms) or
the maximum DC voltage that can be applied continuously.
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.
Maximum energy of less than ±10 % of the varistor voltage
change when the standard impulse (2 ms) is applied one time.
Maximum current of less than ±10 % of the varistor voltage change
when impulse current (8/20 μs) is applied twice continuously with an
interval of 5 minutes.
