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