QUARTZ

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 54MHz in fundamental mode. Their small size and low

mass makes these crystals ideal for miniaturized hand-held equipment

and similar high-density applications.
