EURO QUARTZ X22 CRYSTALS 16.0MHz to 60MHz 2.5 x 2.0 x 0.6mm SMD Frequency range 16MHz to 60MHz, 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 60MHz in fundamental mode. Their small size (2.5 x 2.0mm) and low mass makes these crystals ideal for miniaturized hand-held equipment and similar high-density applications.
