General Description
The CX-6V-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.
 Miniature tuning fork design
 Ultra-low profile (1mm)
 High shock resistance
 Designed for low power applications
 Compatible with hybrid or PCB packaging
 Low ageing
 Full military environmental testing available
 Ideal for battery operated applications
