Abstract :
A low firing-temperature lanthanum-modified lead-zirconate titanate (PLZT) dielectric has been developed to meet EIA Characteristic X7R specifications. Multilayer ceramic capacitors made from this material were sintered below 1100°C and exhibited the following electrical characteristics: dielectric constant, 2050; dissipation factor at I kHz, 1 Vrms/mil of dielectric <0.25 percent; BX temperature-voltage characteristic, 90-100 V/mil; insulation resistance at 25°C, 50 V/mil, > 106 
-F, and at + 125°C, 50 V/mil, > 105 -F. Long-term life test at 2 x rated voltage made very little change in any of the electrical properties.
