Introduction Ceramic capacitors are those wherein the dielectric material is a high-temperature, sintered, inorganic ceramic compound. As a general rule, these materials are based on mixtures of complex titanates or niobate compounds, i.e., barium titanate, titanium oxide, calcium titanate, strontium titanate, etc. Stannate and zirconate compounds are also used. Because of the great variety of electrical characteristics found in ceramic capacitors, the Electronic Component Industry Association (ECIA) has categorized ceramic capacitors into four separate classes.
