■ Performance Characteristics
Characteristics
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 %
———
The voltage between two terminals with the specified measuring
CmA
Varistor Voltage
current CmA DC applied is called Vc or V . The measurement
should be made as fast as possible to avoid heat effects.
Maximum Allowable
Voltage
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).
Clamping Voltage
Rated Power
To meet the
specified value.
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 Energy
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.
