Abstract

In order to improve the ESD(Electrical Static Discharge) resistance of multilayer chip varistors, we have investigated ZnO-$Pr_6O_{11}$ based chip varistor by applying tape casting technology, whose fundamental component were ZnO : $Pr_6O_{11}$ :$Co_3O_4$: $Y_2O_3$: $Al_2O_3$=93.67: 2.53:2.53:1.25 : 0.015 (wt %). The effect of sintering condition on the multilayer chip varistors and electric properties was studied. The electrical properties and ESD resistance of multilayer chip varistor could be influenced the sintering temperature and condition.
