1 / 2 page CX-4V-SM 30kHz to 200kHz MINIATURE SMD CRYSTAL CX-4V-SM 30kHz to 200kHz ULTRA-MINIATURE SMD CRYSTAL General Description The ultra-miniature CX-4V-SM quartz crystals are hermetically sealed in a very small surface-mount package measuring 5.0mm x 1.83mm. The high quality tuning-fork resonator is intended for use in Pierce oscillators. (Single inverter.) Outline Surface-mount - infrared, vapour phase, wave solder or epoxy mount techniques Low profile, hermetically sealed package Available with glass or ceramic lid High shock and vibration resistance Custom designs available Full military environmental testing available Specification CX-4V-SM Package Dimensions Dimension “C” SM1 1.14 1.27 SM2 1.17 1.30 SM3 1.22 1.35 Glass Lid (mm max.)
