General Description
The ultra-miniature CX-4V-SM quartz crystals are hermetically
sealed in a very small surface-mount package measuring 5.0mm x
1.83mm. The high quality tuning-fork resonator is intended for
use in Pierce oscillators. (Single inverter.)
 Surface-mount - infrared, vapour phase,
wave solder or epoxy mount techniques
 Low profile, hermetically sealed package
 Available with glass or ceramic lid
 High shock and vibration resistance
 Custom designs available
 Full military environmental testing available
