General Description
The miniature CX-3V-SM crystals are leadless devices designed for
surface-mounting on printed circuit boards or hybrid substrates.
These crystals are intended for use in Pierce oscillators.
Hermetically sealed in a rugged, miniature ceramic package the
crystals are produced using a photo-lithographic process giving
repeatability and consistency.
