MULTILAYER CHIP VARISTORS
Terminology
①
Working Voltage
Vw(dc) - Maximum Continuous DC Voltage with which the waveform is flat. When a ripple voltage is
supplied as from a rectifier source, make sure that the peak voltage is kept under the Vdcm.
Vw(ac) - Maximum Continuous AC Voltage from a sine-wave shape. When the distortion in the waveform is
extensive, make sure that the peak voltage is less than
√
2 times the Vw (AC)
②
Varistor Voltage ( Vb (@1mA) , Breakdown Voltage )
The varistor terminal voltage which measured with supplying 1㎃ DC current.
③
Maximum Transient Clamping Voltage ( Vc )
The peak terminal voltage which measured with an 8/20㎲ impulse of a given peak current
Transient Energy Rating

④
Maximum Transient Peak Current ( Ip )
Maximum single peak current which is based on 8/20㎲ current wave shape , without the device failure
⑤
Maximum Transient Energy ( Et )
Maximum allowable transient energy for a single impulse of 10/1000㎲ current without device failure
⑥
Capacitance
The Capacitance measured at a specified frequency 1MHz and zero voltage bias with 0.5 Vrms
