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 (R1): D (TO P) Motional Capacitance (C1): Quality Factor (Q): A Shunt Capacitance (C0): Calibration Tolerance*: D Outline B C Load Capacitance: Drive Level: CX-6-SM Package Dimensions Dimension Temperature Stability**: Typical Maximum (mm) (mm) Ageing, first year: Vibration, survival: A 6.73 7.11 B 2.62 2.90 C - see below D 1.27 1.52 Dimension Glass Lid Ceramic Lid C (mm max.)
