Ceramic Capacitor


ceramic capacitor

[sə′ram·ik kə′pas·əd·ər] (electricity) A capacitor whose dielectric is a ceramic material such as steatite or barium titanate, the composition of which can be varied to give a wide range of temperature coefficients.

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.
