Multilayer ceramic capacitors based on Bi(Zn,Ti)O.sub.3--BaTiO.sub.3 dielectrics can be integrated with wide band gap power electronics. The large permittivity values can be stable with both voltage and temperature; combined with the low equivalent series resistance typical of ceramic capacitors, these characteristics make the materials extremely attractive for high operating temperature inverter applications. In addition, the high resistivity values and large activation energies provide reliability over a long capacitor lifetime.
