The mica group comprises 37 phyllosilicate minerals. All crystallize in the monoclinic system, with a tendency towards pseudohexagonal crystals, and are similar in structure but vary in chemical composition. Micas are translucent to opaque with a distinct vitreous or pearly luster, and different mica minerals display colors ranging from white to green or red to black. Deposits of mica tend to have a flaky or platy appearance.

Mica a mineral, is one of the oldest dielectric materials used in capacitor construction. Mica is very stable electrically, mechanically, and chemically. It has a dielectric constant in the range 5-7. The crystalline structure of Mica is asymmetrical, and so while the binding forces in one plane are strong, those along a perpendicular plane are very weak.
Mica capacitor is of two types. One uses natural minerals and the other uses silver mica as a dielectric. "Clamped capacitor" uses natural minerals as a dielectric. Whereas "Silver mica capacitor" uses silver mica as …

In 1896, the first electrolytic capacitor was patented by using a less impurity etching aluminum leaf with alumina as dielectric. Some prominent capacitors have also appeared in succession including mica dielectric capacitor (1909), polyethylene terephthalate–based capacitor (1941), and plastic dielectric capacitor (1959).
Capacitors with a mica dielectric have significantly higher Q than other capacitors partly because of ESR (equivalent series resistance) that is 10 to 20% lower. Lower ESR also leads to lower losses, less self-heating, and the ability to tolerate higher currents. Mica capacitors are incredibly stable over time, temperature, frequency, and voltage, proving …

Mica capacitors utilize the natural mineral mica as their dielectric material. Mica is a silicate mineral, and because it is made from a mineral, it maintains stable characteristics even at high temperatures. It also has good high-frequency characteristics. Capacitance tolerance, which indicates the accuracy of capacitance, can be made very small, and since equivalent series …
