Uac shall be a substantially sinusoidal voltage (less than 5% total harmonic distortion). 2) 壓敏電壓：直流參考電流流過壓敏電阻器时，壓敏電阻器兩端的直流電壓值。 Varistor voltage: dc voltage across the varistor when the dc reference current flows through the varistor. 3) 標稱脈衝電流：是一個電流峰值，它是以每分鐘2次的方式用8/20μs脈衝電流衝擊100次，壓敏電阻器可以 通過的電大峰值電流的1/10。 Nominal pulse current: it is a current peak value. It is pulsed 100 times with 8/20μs pulse current in 2 times per minute, and the varistor can pass 1/10 of the peak current. 4) 抑制電壓：是指在標准大氣條件下，壓敏電阻器中通過標稱脈衝電流时，其兩端呈現的電壓峰值。 Clamping voltage: refers to the voltage peak appearing between the two terminals of a varistor when passing a nominal pulse current under standard atmospheric conditions. 5) 耐衝擊電流：壓敏電阻器允許通過的規定波形的每個脈衝的最大電流值。 Withstanding surge current: the maximum current value of each pulse of the specified waveform that the varistor is allowed to pass. 6) 能量耐量：能被壓敏電阻器吸收指定波形的最大單個脈衝能量，除非另有規定應使用10/1000μs脈衝。 Maximum energy: the maximum single pulse energy of the specified waveform that can be absorbed by the varistor. Unless otherwise specified, 10/1000μs pulses should be used. 7) 額定功耗：在25℃的环境溫度下的最大允許功耗。 Rated power: the maximum allowable power dissipation of varistors at an ambient temperature of 25ºC. 8) 漏電流：在25℃或規定的其他溫度下，施加最大直流電壓时，通過壓敏電阻器中的電流。 Leakage current: the current through the varistor at the maximum dc voltage applied at 25ºC or other specified temperature.
