Abstract :
In response to the demand for MLCs with high capacitance per units volume (C/V value), Y7R-designated 6.8 μF MLCs with 240 dielectric layers 3.2 μm thick were successfully fabricated in EIA1206 size (3.2 mm×1.6 mm×1.5 mm) using a relaxor dielectric ceramic. The C/V value of this MLC is approximately 900 μF/cm3, which is comparable with that for tantalum capacitors. In addition, the new MLC has a low dissipation factor of 1.3% and stable dependence of capacitance on dc bias voltage as compared with BaTiO3-based MLCs. This new relaxor-based MLC exhibits indicate the potential for replacing tantalum capacitors
