EURO QUARTZ X32 CRYSTALS 3.2 x 2.5 x 0.7mm SMD 12.0MHz to 60MHz FEATURES Frequency range 12MHz to 60MHz, fundamental mode Ultra-small package 3.2mm x 2.5mm x 0.6mm Packaged in standard EIA tape and reel Ideal for PDAs, hand-held GPS, PCMCIA etc. DESCRIPTION X32 crystals are ultra-miniature AT-cut crystals covering the frequency range 12MHz to 60MHz in fundamental mode and up to 150MHz in 3rd overtone mode. Their small size and low mass makes these crystals ideal for miniaturized hand-held equipment and similar high-density applications.
