 Varistor Voltage (V1mA)
The voltage across the varistor measured with the specified DC current 1mA.
 Max. Continuous (or Operating) Voltage (Vac/Vdc)
The max. continuous or operating voltage (AC/DC) that can be applied continuously across the varistor.
 Max. Clamping Voltage (Vp)
The max. voltage across the varistor with the specified standard impulse current (Ip, 8/20μs waveform) applied as shown
below.

 Max. Energy (Wmax)
The max. energy within the varistor voltage change of ±10% when a single impulse current of 10/1000μs is applied.
 Max. Surge Current (Imax)
The max. current within the varistor voltage change of ±10% with a single standard impulse current of 8/20μs is applied or
two times with an interval of 5 minutes.
 Rated Power (P)
The power can be applied in the specified ambient temperature.
 Reference Capacitance (Cp)
The capacitance of the varistor at a specified frequency (1KHz or 1MHz) and bias (1Vp-p).
