EURO QUARTZ X11 CRYSTALS 24.0MHz to 48.0MHz 1.6 x 1.2 x 0.4mm SMD Frequency range 24MHz to 48MHz, fundamental mode Ultra-miniature package 1.6 x 1.2 x 0.4mm Packaged in standard EIA tape and reel Exceptionally low ageing High shock and vibration resistance Ideal for PDAs, hand-held GPS, PCMCIA etc. OUTLINE & DIMENSIONS DESCRIPTION X11 crystals are ultra-miniature AT-cut crystals covering the frequency range 24MHz to 48MHz in fundamental mode. Their exceptionally small outline (1.6 x 1.2mm) and low mass coupled with high shock and vibration resistance makes these crystals ideal for miniaturized handheld equipment and similar high-density applications.
