SURFACE-MOUNT CRYSTALS
UM-1SMD and UM-5SMD CRYSTALS
Surface-mount UM-1 and UM-5
DESCRIPTION
UM1-SMD and UM-5SMD crystals are standard UM-1/UM-5 crystals but
with formed leads and fitted with a clip to enable surface-mount PCB
assembly. The crystal therefore offers the ease of surface-mount assembly
with the technical benefits of close-tolerance crystal parameters achievable
by the use of circular AT-Cut crystal blanks.
