CX MINIATURE CRYSTALS 9.6MHz to 160MHz MINIATURE AT-CUT 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-2-SM CX-2-SM Page 1 of 2  General Description The miniature CX-2-SM AT-cut crystals in leadless ceramic packages have been designed for surface-mounting on printed circuit boards or hybrid circuits. These crystal have a low profile and a very small footprint. Manufactured by a photo-lithographic process, the CX-2-SM is a robust crystal that has gained widespread acceptance in the industry.      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 Frequency Range: Calibration Tolerance*: 9.6MHz to 160MHz A ±0.01% (±100ppm) B ±0.1% C ±1.0% 20pF (unless other required) See table See table See table See table 500mW max. -10° to +70°C from ±10ppm -40° to +85°C from ±20ppm -55° to +125°C from ±30ppm ±5ppm max. 3000g 0.3ms, ½ sine 20g rms 10-2,000Hz random -10°~+70°C (commercial) -40°~+85°C (industrial) -55°~+125°C (military) -55°C~+125°C 260°C for 20 seconds 1 (TO P) A I G 2 H 3F D E Load Capacitance: Motional Resistance (R): Motional Capacitance (C): Quality Factor (Q): Shunt Capacitance (C): Drive Level: Temperature Stability**: Ageing, first year: Shock, survival***: Vibration, survival: Operating Temperature: Storage Temperature: Process Temperature: B C Outline Terminal 1 is electrically connected to terminal 3 CX-2-SM Package Dimensions Dimension Typical (mm) Maximum (mm) A B C D E F G H I Dimension “C” 6.60 2.39 0.89 1.50 1.27 2.67 3.94 5.33 Glass Lid (mm max.) 6.99 2.74 see below 1.14 1.75 1.52 2.92 4.19 5.59 Ceramic Lid (mm max.)
