General Description
The miniature CX-1-SM crystals in leadless ceramic packages have
been designed for surface-mounting on printed circuit boards or
hybrid circuits. It is a robust crystal that has gained widespread
acceptance in the industry.
 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
