CX MINIATURE CRYSTALS 9.6MHz to 160MHz ULTRA-LOW PROFILE MINIATURE SMD CRYSTAL EURO QUARTZ Telephone: +44(0)1460 230000 Fax: +44(0)1460 230001 Email: sales@euroquartz.co.uk Web: www.euroquartz.co.uk CX-6-SM CX-6-SM Page 1 of 2 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 Specification Frequency Range: Motional Resistance (R): Motional Capacitance (C): Quality Factor (Q): Shunt Capacitance (C): D (TO P) A D Calibration Tolerance*: Outline B C Load Capacitance: Drive Level: Temperature Stability**: CX-6-SM Package Dimensions Dimension Typical (mm) Maximum (mm) Ageing, first year: Shock, survival***: Vibration, survival: Operating Temperature: A B C D Dimension “C” 6.73 2.62 1.27 Glass Lid (mm max.) 7.11 2.90 see below 1.52 Ceramic Lid (mm max.)
