A NEW RELAXOR DIELECTRIC FOR HIGH-VOLTAGE MULTILAYER CERAMIC CAPACITORS WITH LARGE CAPACITANCE

A new ceramic dielectric, based on (Pb0.65Ba0.35)(Zr0.7Ti0.3)O3 has be en developed. This dielectric, fired at low temperature of 1080-degree s-C, showed a high dielectric constant of 4500, a less than 0.3% dissi pation factor and flat temperature characteristics of capacitance sati sfying Y5P specifications in the EIA (Electronic Industries Associatio n) Standard. Evaluation as a multilayer ceramic capacitor (MLC) reveal ed an excellent capacitance dependence under a high DC field. Thus, th is dielectric is one of the promising candidates for high voltage MLCs with large capacitance.
