X4115 SERIES CRYSTALS
32.768kHz
DESCRIPTION
X4115 crystals are 32.768kHz in an ultra-miniature package. The part
is designed to provide the smallest possible component size for real-
time clock applications. Their miniature size and rugged construction
make them ideal for battery powered, hand-held equipment.
