X21-20.000-12-30/30/-40+85 Mercury United

X21 CRYSTALS Frequency range 20MHz to 54MHz, fundamental mode 2.05 x 1.65 x 0.6mm SMD Ultra-miniature package 2.05 x 1.65 x 0.6mm Packaged in standard EIA tape and reel Ideal for PDAs, hand-held GPS, PCMCIA etc. Extremely low ageing and shock & vibration resistance OUTLINE & DIMENSIONS DESCRIPTION X21 crystals are ultra-miniature AT-cut crystals covering the frequency range 20.0MHz to 54.0MHz in fundamental mode. The X21 crystal package is grounded via the top metal lid and two solder pads. the part exhibits very low ageing and has high shock and vibration resistance. The small size and low mass makes these crystals ideal for miniaturized hand-held equipment and similar high-density applications.
