All BME capacitors with C0G dielectric material were processed for the fabrication of BME capacitors as following: High purity powders of nominal formulation (Ca. 0.7Sr 0.3) (Zr 0.97Ti 0.03)O 3 were used with an average particle size of 0.7μm. The dielectric slips were prepared for tape-casting by milling the above powders in water for 16 hours.
