The invention relates to a ceramic multilayer capacitor having a number of ceramic layers on the basis of a doped (Ba,Ca)[Ti,Zr]O3 as well as a number of electrode layers of Ni, the ceramic layers and the electrode layers being alternately stacked to form a multilayer structure which is provided with electric connections at two side faces, said electric connections being connected to a number of the electrode layers. The invention is characterized in that the composition of the main component of the doped (Ba,Ca)[Ti,Zr]O3 corresponds to the formula(Ba1-xCax)(Ti1-a-b-yZryMnaMobAc)kO3- delta wherein: 0.00</=x</=0.05 0.10</=y</=0.25 0.00<a</=0.01 0.00<b</=0.01 0.00</=c</=0.01 0.99<k</=0.999 and wherein A stands for at least one element selected from the series including Y, Ho, Dy, Er, Yb, Ga, Ni, Mg, Zn and Al, the elements Y, Ga and Zn being preferred. The invention also relates to a ceramic composition of this kind as well as to a method for the manufacture of the above-mentioned ceramic multilayer capacitors. |
