MICA PLATES FOR CAPACITORS
mica plates are specially made of superior quality muscovite
ruby clear mica films, split and gauged to a specified range
of thickness varying between 20 to 100 microns into a close
controllable tolerance within a micron, suitable for use in
the manufacture of silvered mica plates and mica capacitors.
Plain smooth surface, clean punched sharp edges, uniform thickness,
free from metallic stains, spots, finger prints, scratches,
cracks, tears, pin-holes, stones, buckles, ridges, etc., are
some of the important points observed while manufacturing cut
mica plates. They are manufactured as per ASTM Specifications:
