UULLTTRRAA--LLOOWW PPRROOFFIILLEE
MMIINNIIAATTUURREE SSMMDD CCRRYYSSTTAALL
Miniature tuning fork design
Ultra-low profile (1mm)
High shock resistance
Designed for low power applications
Compatible with hybrid or PCB packaging
Low ageing
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.
Full military environmental testing available
Ideal for battery operated applications
