There are two different types of mica capacitors: silver mica capacitors and clamped mica capacitors. We no longer use clamped mica capacitors in electrical systems and circuits and they are now seen as obsolete components. This is because silver mica capacitors have much better characteristics than clamped mica capacitors.
Mica capacitor is one kind of capacitor where the mica (silicate mineral) is used as a dielectric material that can be found in rocks, granites, etc. This material plays a key role in electrical applications like an electrical insulator.
Silver mica capacitors are made by directly putting a layer of silver on the mica surface. This is then layered up until the required level of capacitance has been reached. Once the correct amount of layers has been added electrodes are added and the capacitor is then enclosed within a resin.
This is because silver mica capacitors have much better characteristics than clamped mica capacitors. 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.
The average temperature coefficient is around 50 ppm/°C. Mica capacitors have low resistive and inductive losses (high Q factor). Their characteristics are mostly frequency-independent, which allows for their use at high frequency. These superior characteristics come at a price: silver mica capacitors are bulky and expensive.
Mica capacitors are extremely accurate and stable components, this reflects the fact that their capacitance level hardly changes over time. The reason why they are so stable is the way that they are designed, as there are no air gaps present when they have been manufactured and designed.

What is Mica Capacitor – Construction & Its Working
In this capacitor, material like mica restricts the flow of current, so it can also be used in trimmer capacitors. The dielectric materials used in mica capacitor are white mica, muscovite, rose mica, amber mica, and ruby but from these three materials, muscovite mica material is used as a dielectric in mica capacitor manufacturing most frequently.
