Description:
The NTE Metal Oxide Varistors feature a barrier layer that gives the user fast response time. These devices have a high
transient current handling capability when high voltage is applied. Static resistance is, however, very high under low volt-
age conditions, permitting low standby drain currents.
The NTE 1V Series Varistors have a non−linear voltage/current characteristic as expressed by the relationship:

Electrical Ratings:
Varistor Voltage
The voltage across the varistor at a DC current of 1.0mA.
Energy
The maximum electrical energy which can be dissipated within the varistor by a single impulse of 10 x 1000μs current
waveform with continuous voltage applied. Energy ratings are based on a shift of varistor voltage of less than 10% of the
initial value. The unit is expressed in joules.
Peak Current
The maximum current allowable for a single pulse of 8 x 20μs exponential waveform.
