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 OUTLINE & DIMENSIONS 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.
