Ceramic Capacitor

[sə′ram·ik kə′pas·əd·ər]Ceramic Capacitor
a capacitor in which the dielectric is a ceramic, usually based on titanates of zirconium (ZrTiO3), calcium (CaTiO3), nickel (NiTiO3), and barium (BaTiO3). In some special cases the ceramics used for capacitors are based on Al2O3, SiO2, MgO, and other compounds. The capacitance of ceramic capacitors ranges from fractions of a picofarad to several microfarads; their operating voltage ranges from several dozen volts to dozens of kilovolts.
