SURFACE-MOUNT CRYSTALS MJ2 CRYSTALS 5mm x 3.2mm SMD 2 Pad DESCRIPTION OUTLINES AND DIMENSIONS 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. 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 25ºC*: 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 +70°C -40°~+85°C 5pF maximum 16pF <±5ppm per year at +25°C 100mW max 10s maximum at 235°C ±5°C Ceramic base, ceramic lid, epoxy seal 12mm EIA tape and reel 1000 pieces per reel * Note: Tighter tolerance, stability and lower ESR parameters are available, check with Euroquartz technical sales.
