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 = KVn

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:

D High Transient Current Capability – up to 6500A

D Fast Response Time – less than 35ns

D Excellent Voltage Clamping Characteristics

D Very Low Temperature Coefficient

D The Value for “n” is Greater

D Very Low Leakage Current

D Low Capacitance

D 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 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.
