SPECIFICATION
DESCRIPTION
Um-1 and UM-5 crystals are a long-established design, being widely
used in telecommunications applications where their compact size
and ease of producing to close tolerances makes them an ideal
crystal. In addition to the standard packages a 'Slimline' package is
also available.
