Metal Oxide VaristOrs - eV series  
Definition of Terms (according to IEEE specifications C62.33)  
Average Power Dissipation: Tested using two consecutive pulses at rated peak current using a 10/1000µs test  
waveform with a minimum pulse period of 60 seconds between pulses (IEC 61000-4-5).  
Rated RMS Voltage, Rated DC Voltage: The maximum designated values of power system voltage that may be applied  
continuously between the terminals of a device.  
Varistor Voltage: Test characteristic that is used to classify varistors by type. A test current of 1mA DC is typically  
used to determine varistor voltage classification type. Varistor voltage clamping characteristics can be defined  
at various test levels.  
Rated Peak Single Pulse Transient Current: Maximum surge current, 8/20μs waveform which a varistor is rated to  
withstand for a single surge.  
Rated Single Pulse Transient Energy: Maximum allowable energy for a single impulse (see specified waveforms).  
Maximum Clamping Voltage: Measured peak voltage across the device terminals when a current impulse of specified  
amplitude and waveform is conducted through the varistor.  
Typical Capacitance: Typical capacitance values are measured at a test frequency of 1KHZ.

Voltage change 10% from initially measured Varistor Voltage. When  
determining if varistor is within aforementioned criteria the same temperature  
must be observed as was used for initial Varistor Voltage measurements.  
Failure Criteria  
*Rating is for standard epoxy, for flame retardant coating (suffix “S”) disk sizes 5mm to 20mm rating is 2000 VDC, for disk  
sizes 22mm & 34mm rating is 2500VDC.
