DESCRIPTION
The CC1A-T1AH 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.
For extreme operating temperature ranges up to 200°C.
Operates in fundamental mode.
High shock and vibration resistant.
100% Pb-free, RoHS-compliant.
