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. References to mica capacitors from the 1920s often refer to this type.
Standard silver mica capacitors are normally designed to handle voltages from 100 to 1000 volts. High-voltage RF transmitter applications can call for higher tolerances.
