If fill mica between the air gaps between capacitors will how?
We need consider mica as conductor?

berkeman said:No, mica is an insulator. Look up the dielectric constant of mica, and compare that value to the dielectric constant of air. Do you see now why mica is used in capacitor construction?
ahjie said:If the dielectric constant of mica is 5, then apply this formula?(C=κC。)
so make the capacitance of that capacitors higher?is it like this?
Fill mica is a type of mineral that has excellent dielectric properties, making it a suitable material for use in capacitors. It is used to insulate the conductive plates in a capacitor and prevent electrical leakage.
Fill mica has a high breakdown voltage and low dielectric loss, which allows for a higher capacitance and better energy storage in a capacitor. It also has good thermal stability and can withstand high temperatures, making it suitable for use in a wide range of applications.
One potential disadvantage of using fill mica in capacitors is its high cost compared to other materials. It can also be brittle and difficult to shape, which can make it challenging to use in certain capacitor designs.
Fill mica capacitors are commonly used in high-frequency and high-voltage applications, such as in power supplies, electronic filters, and radio frequency circuits. They are also used in spark plugs, ignition systems, and other automotive components.
Yes, there are various alternatives to fill mica, including ceramic, plastic film, and electrolytic capacitors. Each type has its advantages and disadvantages, and the choice of capacitor material depends on the specific application and performance requirements.
