Disc Ceramic Capacitors General Specifications - Class III Semi Conducting DIELECTRIC - CLASS III A thin dielectric layer is grown on a disc of conductive ceramic. Very large capacitances can be obtained due to reduced thickness of this barrier layer and its inherently high dielectric constant. Due to its small dimensions, they are a less expensive replacement of multilayer ceramic or polyester capacitors. An equivalent circuit is shown below: Meets IEC 324 (1970).
