DESCRIPTION
X42 crystals are micro-miniature surface-mount mount crystals. The crystals have a gold plated ceramic base with a seam welded metal lid providing a stable crystal with very low ageing. The rugged construction ensures that this crystal has high shock and vibration resistance. The crystal has been optimized for WI-Fi applications: Bluetooth/ Bluetooth Low Energy (BLE), Bluetooth Smart, Zigbee, ISM, Wi-FI / WLAN, LPWAN and others. Miniature package: 4.0 x 2.5 x 0.6mm Gold-plated ceramic base with metal seam-welded package Very low ageing Optimized for Wi-Fi applications High shock and vibration resistance OUTLINE & DIMENSIONS Operating Mode: AT-Cut Fundamental: Calibration Tolerance at 25ºC: ±10ppm Frequency stability -20° to +70°C ±10ppm -40° to +85°C ±15ppm -40° to +105°C ±30ppm Storage Temperature: -50°~+105°C Equivalent Series Resistance: Shunt Capacitance (C0): 2pF to 4pF typical, 5pF maximum Load Capacitance (CL): Series or from 10pF to 32pF Ageing: <±ppm per first year at +25°C Drive level: 100 µW maximum Reflow Soldering: 10s maximum at 260°C twice or 180s at 230°C, once. Packaging: 12mm EIA tape and reel SPECIFICATION PART NUMBER GENERATION Part numbers for X42-W crystals are generated as follows: X42-W CRYSTALS
