UM1SMD Datasheet, PDF (1/1 Pages) EUROQUARTZ limited – SMD form of UM-1 & UM-5 Crystals

EURO QUARTZ
UM-1SMD amd UM-5SMD Crystals
SMD form of UM-1 & UM-5 Crystals
1.0MHz to 200.0MHz
Tight tolerance and stability, ideal for comms. applications
AT-Cut round crystal blank, optimized for low harmonics
Available up to 200MHz using 5th overtone mode
Annealed and pre-aged for low frequency drift
Surface mount assembly
DESCRIPTION
UM-1SMD and UM-5SMD crystals are standard UM-1 and UM-5
crystals with ormed leads and fitted with a clip to enable surface
mounting. This offers the benefits of maintaining a highly specified
crystal while facilitating surface mount assembly.
