  • 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

    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. Operating Ambient Temperature : -40° to +85°C Storage Temperature: -40° to +125°C Response Time : less than 35ns Voltage Temperature Coefficient less than 0.05%/ : °C Non-Linear Exponent: 15 to 50 Maximum Leakage Current: 10µA
    Cautions:
    NTE varistors short-circuit when subjected to surges beyond their peak current and energy ratings. NTE varistors short-circuit when operated at steady-state voltages well beyond their voltage ratings, which may eventually result in open-circuiting leaving the circuit without protection.
    The following precautions should be taken to minimize this potential hazard:
    • Fusing the varistor to limit high fault currents.
    • Protecting the surrounding circuitry by physical shielding.
    • Locating the varistor away from other components.
