General Description
The CX-6-SM AT-cut 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)
Ideal for use with microprocessors
Designed for low power applications
Compatible with hybrid or PCB packaging
High shock and vibration resistance
Low ageing
Full military environmental testing available
Custom designs available
