Metal Oxide Varistors (MOV)
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:
I = KV
n
Where I = The current in amperes
V = The voltage
K = A constant
n = A constant which shows the dependence of
the voltage V upon the current I. It is called
the voltage–dependant index
Features:
High Transient Current Capability – up to 6500A
Fast Response Time – less than 35ns
Excellent Voltage Clamping Characteristics
Very Low Temperature Coefficient
Low Standby Current
High Energy Capability
The Value for “n” is Greater
Very Low Leakage Current
Low Capacitance
Low Overshoot Characteristics
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 1000
μ
s 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 20
μ
s exponential waveform.
