摘要：
A ceramic dielectric composition contains a base material powder represented by one or more of (Ca1−xSrx)(Zr1−yTiy)O3, Ca(Zr1−yTiy)O3, Sr(Zr1−yTiy)O3, (Ca1−xSrx)ZrO3, and (Ca1−xSrx)TiO3, in which x and y satisfy 0≦x≦1.0 and 0.2≦y≦0.9, respectively. The ceramic dielectric composition may have high room-temperature permittivity and excellent ESD protection characteristics and may secure withstand voltage characteristics while implementing relatively high capacitance.
