The CC7A-T1A is a high frequency SMT Quartz Crystal Unit that
incorporates an AT-cut Quartz Crystal Resonator. It operates under
vacuum in a hermetically sealed ceramic package with ceramic lid.
FEATURES
Outstanding hermetic sealing with gold-tin preform.
High stability and low aging guaranteed by hermetic sealing.
Available for extended operating temperature range.
Small size, low profile, lightweight (9.2 mg).
Operates in fundamental mode.
High shock and vibration resistant.
100% Pb-free, RoHS-compliant.
