DESCRIPTION
X3215 crystals provide 32.768kHz in an ultra-miniature package. The
part is designed to provide the smallest possible component size for
real-time clock applications. The micro-miniature size and rugged
construction make them ideal for real time clocks and battery powered,
hand-held equipment.
