<p>PURPOSE:To obtain a voltage non-linear resistor having desirable resistance to surge and electro-mechanical lifetime with little variance in electric characteristics, by specifying the thickness and the porosity of a metallicon electrode. CONSTITUTION:In a voltage non-linear resistor subjected to extremely large current, porosity of its metallicon electrode layer and a certain range of thicknesses thereof improve resistance to surge and electro-mechanical lifetime. The porosity of the metallicon electrode should be Y<=X/10+7 when Y is a porosity(%) and X is a thickness of the metallicon(mum). Thus, the voltage non- linear resistor is allowed to have desirable characteristics with little variance in various properties, such as resistance to surge, electro-mechanical lifetime or the like.</p> |
