| SURFACE-MOUNT CRYSTALS MJ2 CRYSTALS 5mm x 3.2mm SMD 2 Pad DESCRIPTION MJ crystals are ultra-miniature surface-mount mount crystals. Produced with both ceramic substrate and ceramic lid the compact size and low mass make this an ideal crystal for high-density applications. OUTLINES AND DIMENSIONS FEATURES * * * * * Ultra miniature size: 5.0mm x 3.2mm x 1.2mm height All-ceramic construction with epoxy seal and Au plated pads Extremely low ageing High shock and vibration resistance Ideal for PDAs, GPS, Wireless LAN, and hand-held equipment GENERAL SPECIFICATION Frequency Range AT-Cut Fundamental: Calibration Tolerance at 25C*: Frequency stability over temp*: Storage Temperature: Shunt Capacitance (C0): Load Capacitance (CL): Ageing: Drive level: Reflow Soldering: Holder: Supply Packaging: 12MHz to 50MHz 50ppm 50ppm over -20 to +70C -40~+85C 5pF maximum 16pF <5ppm per year at +25C 100mW max 10s maximum at 235C 5C Ceramic base, ceramic lid, epoxy seal 12mm EIA tape and reel 1000 pieces per reel PART NUMBER GENERATION MJ2 crystal part numbers are derived as follows: Example: 16.000MHz MJ2/ 20/50/10/16pF * Note: Tighter tolerance, stability and lower ESR parameters are available, check with Euroquartz technical sales. EQUIVALENT SERIES RESISTANCE Frequency (MHz) 12.0 ~ 15.99 16.0 ~ 19.99 20.0 ~ 50.0 ESR (max) (Ohms) 80 60 40 Frequency Package - MJ2 Calibration Tolerance at 25C (in ppm) Temperature Stability (in ppm) Operating Temperature Range -10~+60C (lower figure of temperature range) Circuit Condition CL = 16pF STOCKHOLDING AND CUSTOM PARTS Certain frequencies and specification of MJ2 crystals are stocked by Euroquartz. Custom frequencies and specifications are readily manufactured to order on short lead times. Contact Euroquartz sales office for details.
