Global Mica Capacitors Market Analysis , Size , Share , Growth and Forecast to 2021- Hexa Research
" 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 is a group of natural minerals . Silver mica capacitors are the ones that use mi ca 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 .
