Mica Capacitor

mica capacitor

[′mī·kə kə′pas·əd·ər]
(electricity)
A capacitor whose dielectric consists of thin rectangular sheets of mica and whose electrodes are either thin sheets of metal foil stacked alternately with mica sheets, or thin deposits of silver applied to one surface of each mica sheet.

Mica Capacitor

 

a capacitor in which the dielectric is sheet mica (muscovite, phlogopite) split into thin layers (to 0.01 mm) and the electrodes are either of foil or of metal that is deposited directly on the mica through evaporation of the metal in a vacuum. The capacitance of mica capacitors ranges from several picofarads to hundreds of nanofarads; the rated voltage reaches tens of kilovolts. Mica capacitors are used for frequencies of up to several megahertz.
