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).
