General Description
The CX-6-SM quartz crystals are leadless devices designed for
surface mounting on printed circuit boards or hybrid substrates.
The crystals are intended for use in Pierce oscillators. Hermetically
sealed in a miniature ceramic package, the crystals are produced
utilizing a photo-lithographic process ensuring consistent high
quality production units.
