Metal Oxide Varistors - 07D Series
Electrical Rating
ltem
Test Condition / Description
Requirement
The voltage between two terminals with the specified measuring current 1mA.
DC applied is call Vb.
Varistor Voltage
Maximum Allowable
Voltage
The recommended maximum sine wave voltage (RMS) or the maximum DC
voltage can be applied continuously.
To meet
the specified
value
The maximum average power that can be applied within the specified ambient
temperature.
Rated Wattaget
IEnergy
The maximum energy within the varistor voltage change of ±10% when one impulse
of10/1000μsec. or 2 msec. is applied.
Withstanding Surge
Current
The maximum current within the varistor voltage change of ±10% with the standard
impulse current (8/20μsec.) applied one time.
The change of Vb shall be measured after the impulse listed below is applied 10,000
times continuously with the interval of ten seconds at room temperature.
