EURO QUARTZ X22 CRYSTALS 2.5 x 2.0 x 0.6mm SMD Frequency range 16MHz to 54MHz, fundamental mode Ultra-miniature package 2.5 x 2.0 x 0.6mm Packaged in standard EIA tape and reel Ideal for PDAs, hand-held GPS, PCMCIA etc. DESCRIPTION X22 crystals are ultra-miniature AT-cut crystals covering the frequency range 16MHz to 54MHz in fundamental mode. Their small size and low mass makes these crystals ideal for miniaturized hand-held equipment and similar high-density applications. SPECIFICATION Frequency Range AT-Cut Fundamental: Calibration Tolerance at 25ºC: Frequency stability -10° to +60°C -20° to +70°C -40° to +85°C Storage Temperature: Equivalent Series Resistance: Shunt Capacitance (C0): Load Capacitance (CL): Ageing: Drive level: Reflow Soldering: Packaging: OUTLINE & DIMENSIONS 16.0MHz to 54.0MHz ±10ppm, ±20ppm, ±30ppm from ±10ppm (±5ppm available) from ±10ppm from ±15ppm -50°~+105°C See table 2pF to 4pF typical, 5pF maximum Series or from 9pF to 32pF <±2ppm per year at +25°C 50 microWatt, 100 microW max. 10s maximum at 260°C twice or 180s at 230°C, once.
