l
Multilayer varistor of Zinc oxide ceramic.  
suppresses the pulse noise(ESD, burst-noise) and  
protects the equipment from the transient surge.  
This Varistor is suitable for high-speed signal line  
due to small capacitance.

Test Method  
Specifications  
After securing the specimen by the body with tweezers and  
dipping in to the specified soldering flux, the specimen shall  
be completely immersed into a soldering bath having a  
temperature of 235±5 ¡C for 4±1 seconds. And then the  
specimen shall be visually examined.  
Approximately 75 %  
of the terminals shall  
be covered with new  
solder  
Solderability  
Use the specified soldering flux and solder following:  
Soldering Flux: Ethanol solution of rosin about 25 % by weight  
Solder: Eutectic solder (Sn 63 : Pb 37)  
uniformly,  
After preheating the specimen according to the following  
conditions in Table-1, the specimen shall be completely  
immersed into a soldering bath having a temperature of 270±5  
¡C for 3±0.5 seconds. And then be stored at room No remarkable  
temperature for 24±2 hours. Thereafter, the change of V
