Mica is a group of natural minerals. Silver mica capacitors are the ones that use mica as the dielectric. There are two types of mica capacitors; viz clamped mica capacitors and silver mica capacitors. Clamped mica capacitors are obsolete due to their inferior characteristics. Silver mica capacitors are made by sandwiching mica sheets covered with metal on both the sides.
Mica capacitors are typically used when the design calls for stable, dependable capacitors of moderately small values. They are low-loss capacitors, which allow them to be used at elevated frequencies, and their worth does not change much over time. Mica minerals are very stable electrically, chemically, and mechanically. Because of its exact crystalline structure binding, it has a typical layered structure. This makes it possible to manufacture thin sheets in the order of 0.025-0.125 mm.
The Global mica capacitors are having characteristics as Precision and Tolerance.The smallest amount tolerance for silver mica capacitor values can be as low as ±1. This is much better than virtually all the other types of capacitors. Mica capacitors are very stable and precise. Their capacitance minimally changes over the period of time. This is due to the fact that there are no air gaps in the design that could change over time. Also, the assembly is secluded from moisture and other effects by an epoxy resin. This means that outside effects such as air humidity does not affect mica capacitors. Not only is their capacitance stable over the period of time, it is also stable over a wide temperature, voltage, and frequency range. The average temperature co-efficient is around 50 ppm/°C.
