| EURO QUARTZ 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. X22 CRYSTALS 2.5 x 2.0 x 0.6mm SMD 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. OUTLINE & DIMENSIONS SPECIFICATION Frequency Range AT-Cut Fundamental: Calibration Tolerance at 25C: Frequency stability -10 to +60C -20 to +70C -40 to +85C Storage Temperature: Equivalent Series Resistance: Shunt Capacitance (C0): Load Capacitance (CL): Ageing: Drive level: Reflow Soldering: Packaging: 16.0MHz to 54.0MHz 10ppm, 20ppm, 30ppm from 10ppm (5ppm available) from 10ppm from 15ppm -50~+105C See table 2pF to 4pF typical, 5pF maximum Series or from 9pF to 32pF <2ppm per year at +25C 50 microWatt, 100 microW max. 10s maximum at 260C twice or 180s at 230C, once. EIA tape and reel EQUIVALENT SERIES RESISTANCE Frequency Range MHz 16.0~21.0 21.0~26.0 26.1~54.0 ESR Ohms Max. 100 80 60 PART NUMBER GENERATION Part numbers for MT crystals are generated as follows: Example: 20.000MHz X22/10/30/-10+60/12pF/100R Nominal Frequency Package Calibration tolerance at 25C (ppm) Temperature Stability over temp. range (ppm) Operating Temp.
