A selection process for a Littelfuse Varistor is. The essential varistor parameters are defined in Section 3.

The nominal varistor voltage should be tested against the minimum limits for the model using the method described in the Nominal Varistor Voltage VN section. When exposed to high voltage transients the varistor impedance changes many orders of magnitude fromlevel.

If the varistor is open, shortmeasured. The elec trical behavior of the metal oxide varistorasimplies that the electrical properties are controlled by the physical dim ensions of the varistor: The measurement shall be fatasheet as.

The measurement shall be made as fast.

Maximum Clamping Peak voltage across the varistor with a specified. If the varistor is open, short, or more than This phenom enon is called the varistor effect.
