| Standard test condition |
Environmental conditions under which every
measuring is done without doubt on the measuring results. Unless specified, the
temperature and relative humidity should be to 5 to 35 oC and 45 to 85%
respectively. |

| Varistor voltage |
The varistor voltage is measured with an
impressed current of 1mA (exception, ø5: 0.1mA) and serves to characterize each varistor type. |
To meet the specified value |
| Maximum operating voltage |
The maximum sinusoidal RMS voltage or maximum
DC voltage that can be applied continuoulsy in the specified environmental temperature
range. |
| Maximum clamping voltage |
Maximum clamping voltage is the maximum
voltage Vp between two terminals with the specified standard impulse current Ip (8 x 20µs). |
| Withstanding surge current |
The maximum current within the varistor
voltage change of ±10% with the standard impulse current (8 x 20µs )applies one
or two times. |
| Energy |
The maximum energy within the varistor
voltage change of ± 10% when one impulse of 10/1000 µs or 2 msec is applied. |
| Rated power |
The maximum power that can be applied within
the specified ambient temperature. |
| Capcitance |
The capacitance of varistor is the typical
value measured at 1KHz, 1Vrms max, OV bias and 20 ± 2 oC |
