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.
Ultra-low profile (1mm)
Extensional mode
Ideal for use with microprocessors
Designed for low power applications
Compatible with hybrid or PCB packaging
Low ageing
Full military environmental testing available
Ideal for battery operated applications
