THROUGH-HOLE CRYSTALS
UM-1SL SLIMLINE CRYSTALS
DESCRIPTION
UM-1 Slimline crystals are popular for communications applications such
as pagers where their small size and slimline profile is easily incorporated
into equipment designs. The crystal blank used in this package is capable
of being manufactured to close tolerances and is readily produced with
custom frequencies and specifications.
