PARAMENTERS DEFINITION 10 Varistor (breakdown voltage): The varistor voltage is the voltage across the varistor measured at a specified current IC(0.1mA or 1mA) of specified duration. 10 allowable voltage: The allowable voltage corresponds to the rest state of the varistor. The rest state voltage offers a low leakage current in order to limit the power consumption of the protected device and not to disturb the circuit to be protected. 10 Non linear exponent ( \ ): The varistor voltage-current characteristic is defined by the equation: I=KV \ where K is a constant dependent on geometry, and is the non linear exponent. We usually take two points(v1, I1)(V2, I2) to estimate the of \. log I1/I2 In which, and I2 are the current value \= log V1/V2 corresponding to the voltage value V1 and V2 10 clamping voltage: clamping voltage is the maximum voltage Vp between two terminals with the specified standard impulse current I (8x20 µ sec.). The voltage value is an indication on the protective function of the varistor. HOW TO ORDER
