DESCRIPTION
STATEK's next generation ultra-miniature CX-7V-SM quartz
crystals feature an innovation in quartz crystal miniaturization
design and manufacturing process. The CX-7V-SM quartz
crystals are hermetically sealed in the smallest surface mount
ceramic package in the world! This high quality tuning fork
resonator is intended for use in Pierce oscillators.
