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 voltage 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	High Energy Capability
D Fast Response Time – less than 35ns	D The Value for “n” is Greater
D Excellent Voltage Clamping Characteristics	D Very Low Leakage Current
D Very Low Temperature Coefficient	D	Low Capacitance
D Low Standby Current	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 1000 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 s exponential waveform.
