Silver Mica Capacitors

Silver Mica Capacitor

Silver Mica Capacitors are capacitors that are made from depositing a thin layer of silver on a mica dielectric.

Silver Mica Capacitors are very stable with respect to time; they have tolerances of 1 percent or less. They also have a good temperature coefficient and excellent endurance. However, they don't come in high capacitance values and can be expensive.

They are used in resonance circuits and high-frequency filters, due to good stability with temperature. They are also used in high-voltage circuits, because of their good insulation.

Their temperature coefficient, in regard to oscillators, isn't as low as can be achieved by other types, and some silver micas have been known to behave erratically.
