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. 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. OUTLINE & DIMENSIONS Frequency Range AT-Cut Fundamental: 16.0MHz to 54.0MHz Calibration Tolerance at 25ºC: ±10ppm, ±20ppm, ±30ppm Frequency stability -10° to +60°C from ±10ppm (±5ppm available) -20° to +70°C from ±10ppm -40° to +85°C from ±15ppm Storage Temperature: -50°~+105°C Equivalent Series Resistance: See table Shunt Capacitance (C0): 2pF to 4pF typical, 5pF maximum Load Capacitance (CL): Series or from 9pF to 32pF Ageing: <±2ppm per year at +25°C Drive level: 50 microWatt, 100 microW max. Reflow Soldering: 10s maximum at 260°C twice or 180s at 230°C, once.
