MS2 CRYSTALS
10.7mm x 4.7mm x 2.0mm SMD
DESCRIPTION
The MS2 crystal provides an ideal source of low frequency clock
signals (under 10MHz) in a low-profile SMD package height of
2.0mm. The crystal features a glass to metal substrate and resistance-
welded metal lid offering enhanced hermetic properties. Premium
grade AT-strip crystal plate is mounted at both ends for high shock
and low g sensitivity.
