The CM7V-T1A 0.3 is a low frequency SMT Quartz Crystal Unit that

incorporates a tuning fork Quartz Crystal Resonator. It operates under

vacuum in a hermetically sealed ceramic package with metal lid.

FEATURES

Ultra low proﬁle (maximum height 0.35 mm).

Outstanding hermetic sealing with gold-tin preform.

High stability and low aging guaranteed by hermetic sealing.

Available for extended operating temperature range.

High shock and vibration resistant.

100% Pb-free, RoHS-compliant.
