15 / 24 page  15 Performance Characteristics Characteristics Test Method and Specifications Standard Test Condition Temperature range : 5 to 35 C Relative humidity : 45 to 85% R.H. Varistor Voltage Voltage across the varistor measured at 1 mA DC rectangular pulse current Maximum Allowable Voltage Maximum continuous sinusoidal rms voltage or DC voltage which may be applied within the specified environmental temperature range Maximum Clamping Voltage Peak voltage across the varistor under condition of a specified standard impulse current (8/20µs) Withstanding Surge Current Maximum current across the varistor measured at a given standard waveform (8/20µs) applied one time or two times with the varistor voltage less than ±10% Rated Transient Average Power Dissipation Maximum average power which may be dissipated due to a group of pulses occurring within a specified isolated time period, without causing device failure Maximum Energy The maximum energy within the varistor voltage change of ±10% when one impulse of 2ms or 10/1000µs is applied Capacitance (Reference) Capacitance between the terminals of the varistor measured at 1 kHz, 1 Vrms, zero bias and room temperature (Exception 100pF below measured at 1MHz) Temperature Coefficient of Varistor Voltage (V at 85°C －V at 25°C) /( V at 25°C×60) ×100(%/°C) should be less than -0.05%/°C Withstanding Voltage (Body insulation) The specified voltage shall be applied both terminals of the varistor connected together and metal foil closely wrapped round its body for 1 min without breakdown Performance Characteristics Crest value Time Impulse width |
