Mica Capacitors

Mica Capacitors Points : Mica Capacitors Mica is one of the best natural insulating materials. Consequently capacitors with mica as the dielectric have very low losses and can be made with high voltage ratings (up to 10,00 volt dc. or so). Their capacitance range is from 1 pF to 0.01 uF.
The mica capacitors consist of layers of mica alternated with layers of metal foil. The entire assembly is dipped in plastic or encapsulated in a molded plastic jacket. Mica capacitors are used for audio frequency and radio frequency coupling and tuning.
