The mica dielectric provides a stable capacitance over a wide range of temperatures and frequencies, making them ideal for applications where consistent performance is crucial, such as in precision analog circuits or high-frequency oscillators.
Mica capacitors can withstand high voltages, operate at high temperatures and have low leakage current. Because mica capacitors have a very small inductive characteristic and low losses, they are often used in radio frequency (RF) circuits. Silver is used to form mica capacitor plates.
The tolerance for a mica capacitor can be as low as +/-1%. When compared to something like ceramic which has a tolerance of +/-20%, mica is much more useful in environments where stability is important. It is common in applications where low capacitance but high stability is called for, such as RF transmitters and power circuits.
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.
In low power RF applications, a good replacement for silver mica capacitors is ceramic capacitors. If small capacitance tolerances, low losses and a low temperature coefficient are needed, Class I ceramic capacitors can be used. These ceramic capacitors have characteristics like silver mica capacitors, but at a fraction of the price.
