CX MINIATURE CRYSTALS 18kHz to 600kHz 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-6V-SM Page 1 of 2 General Description The CX-6V-SM 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.         Miniature tuning fork design Ultra-low profile (1mm) High shock resistance Designed for low power applications Compatible with hybrid or PCB packaging Low ageing Full military environmental testing available Ideal for battery operated applications Specification Frequency Range: Functional Mode: Calibration Tolerance*: Motional Resistance (R1): Motional Capacitance (C1): Quality Factor (Q): Shunt Capacitance (C0): Drive Level: Turning Point (T0)**: Temperature Coefficient (k): Ageing, first year: Shock, survival***: Vibration, survival***: Operating Temperature: Storage Temperature: Process Temperature: 18kHz to 600kHz Tuning Fork (Flexure) A, B or C (see table below) See Figure 1 Max.: 18~25kHz, 2x typ. 25~600kHz, 2.5x typ.
