PURPOSE:To obtain a voltage-nonlinear resistance ceramic composition for low-voltage use having excellent resistance to surge current by using zinc oxide as a main component, adding specific amounts of oxides of Bi, Co, Mn and Ti as subsidiary components and adding oxides of Dy, Er, Yb, etc., to the obtained composition. CONSTITUTION:The objective voltage-nonlinear resistance ceramic composition for low-voltage use and useful for the stabilization of circuit voltage of various electronic apparatuses and the absorption of surge and noise is produced by including 0.01-1.00mol% of at least one kind of Dy, Er and Yb in terms of Dy2O3, Er2O3 and Yb2O3 in a composition composed mainly of ZnO and containing Bi, Co, Mn and Ti as subsidiary components in amounts of 0.05-3.00mol%, 0.05-3.00mol%, 0.05-3.00mol% and 0.10-2.00mol% in terms of Bi2O3, Co2O3, MnO2 and TiO2, respectively. |
