OUTLINE & DIMENSIONS

DESCRIPTION

X21 crystals are ultra-miniature AT-cut crystals covering the frequency

range 20MHz to 54MHz in fundamental mode. Their exceptionally

small size (2.0 x 1.6mm) and low mass coupled with high shock and

vibration resistance makes these crystals ideal for miniaturized

handheld equipment and similar high-density applications.
