Silver mica capacitors offer tight tolerances from ±0.05% to ±5%. It is difficult to manufacture silver mica capacitors with large capacitance values, and they run from 0.5 pF to a few nanofarads. Typical capacitance values range from 1 pF to 91,000 pF, while voltage ratings range from 50 V to 2500 V.
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.
Silver mica capacitors are used in high-frequency RF tuned circuits such as those found in filters, oscillators and power amplifiers. In filters, the tolerances and low losses (high Qs) of silver mica capacitors result in precise and predictable tuned-circuit performance.
1.Mica Dielectric: The heart of the capacitor lies within the mica dielectric—a wafer-thin sheet of mica material. Mica assumes this role by virtue of its stability and insulating prowess. 2.Metallic Foil Electrodes: Positioned on either side of the mica dielectric are two metallic foil electrodes.
Silver is used to form mica capacitor plates. Other metals, like copper and aluminum, have been used, but do not perform as well. Silver mica capacitors offer tight tolerances from ±0.05% to ±5%. It is difficult to manufacture silver mica capacitors with large capacitance values, and they run from 0.5 pF to a few nanofarads.
There are two types of mica capacitors: clamped mica capacitors and silver mica capacitors. Clamped mica capacitors are now considered obsolete due to their inferior characteristics. Silver mica capacitors are used instead. They are made by sandwiching mica sheets coated with metal on both sides.
