Introduction to Dielectric Capacitor (i). A capacitor fundamentally is composed of two conducting surfaces or two metal surfaces, which are mutually separated through an insulating medium. The insulating medium is called dielectric. Any one of the materials like air, oil, ceramics, plastics, mica, and glass, etc., can be used as a dielectric.

Definition – A mica capacitor uses mica as the internal dielectric. Mica capacitors come in two different types: clamped and silver mica capacitors. They are extremely stable components and have low resistive and inductive losses. Mica capacitors are created by layering mica sheets that have been coated with metal on either side.
Mica capacitors are also classified as low-loss capacitors, this means that they can be used in high-frequency applications as they are stable and their values do not differ much over time. Silver mica capacitors are generally used for applications where only a small level of capacitance is required.
Not only is their capacitance stable over time, it is also stable over a wide temperature, voltage and frequency range. The average temperature coefficient is around 50 ppm/°C. Mica capacitors have low resistive and inductive losses (high Q factor).
When aluminum and copper were substituted with silver, the performance of mica-metal capacitors increased. Thin sheets of mica separated by thin sheets of silver were stacked to form an assembly in these clamped mica capacitors. Before connecting the mica-silver layers, they were clamped.
As a result, they are suitable for coupling circuits, tuned circuits with high frequencies, power RF circuits, and pulsed applications. The low loss feature of mica capacitors in RF oscillators enables low phase noise and excellent stability. What Construction and properties does a mica capacitor have?
Silver mica capacitors are used in its place of clamped mica due to their lower characteristics. Generally, mica capacitors are low loss capacitors which are used where the high frequency is required and their value doesn't change much over time.
