					Testing Method  
					Standard test  
					conditions  
					Electrical characteristics shall be measured under the following conditions.  
					Temp. : 5 to 35 °C, Relative humidity : 85 ꢀ or less  
					The Varistor voltage is the voltage (VC,or VcmA) between both end terminals of a  
					Varistor when specified current (CmA) is applied to it. The measurement shall be  
					made as quickly as possible to avoid heating effects.  
					To meet the specified  
					value.  
					Varistor voltage  
					Maximum  
					To meet the specified  
					allowable voltage value.  
					The maximum DC voltage that can be applied continuously to a varistor.  
					To meet the specified Capacitance shall be measured at the specified frequency, bias voltage 0 V,  
					Capacitance  
					value.  
					and measuring voltage 0.2 to 2 Vrms.  
					The maximum current measured (Varistor voltage tolerance is within 10 ꢀ)  
					when a standard impulse current of  
					8/20 µ seconds is applied twice with an interval of 5 minutes.  
					Maximum peak  
					current  
					To meet the specified  
					value.  
					The maximum ESD measured (while the varistor voltage is within 30 ꢀ of its  
					nominal value) when exposed to ESD 10 times  
					(five times for each positive-negative polarity) based on IEC61000-4-2.  
					To meet the specified  
					value.  
					Maximum ESD  
					The part shall be immersed into a soldering bath under the conditions below.
