Mica capacitors exhibit low losses, which means they have a high quality factor (Q) and low dissipation factor (DF). For an explanation of these terms, read: The engineer’s capacitor glossary: All terms and acronyms defined. Mica capacitors can withstand high voltages, operate at high temperatures and have low leakage current.
The advantages and disadvantages of mica capacitors mainly include; Stable capacitance, Operates at high temperatures, Withstand at very high voltages, Low losses, Highly accurate and Dielectric provides good insulation, High cost and Proper sealing is required
The largest capacitance mica capacitors can reach values of 1µF, although these are uncommon. Silver mica capacitors are usually rated for voltages between 100 and 1000 volts, although there are special high-voltage mica capacitors designed for RF transmitter use which are rated at up to 10 kV.
There are 2 distinct types of mica capacitor. Now obsolete, these were in use in the early 20th century. They consisted of sheets of mica and copper foil sandwiched together and clamped. These had even worse tolerance and stability than other clamped capacitors since the mica surface is not perfectly flat and smooth.
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.
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.
Construction of Mica Capacitor And its Application
Silver mica capacitors have a comparatively tiny capacitance value (between a few pF, upto a few nF). The largest capacitance capacitors can attain values of 1µF, even though these are unusual.

Silver mica capacitor
Silver mica capacitors are high precision, stable and reliable capacitors. They are available in small values, and are mostly used at high frequencies and in cases where low losses (high Q) and low capacitor change over time is desired. Mica has been used as a capacitor dielectric since the mid-19th century.
