EQ156 CRYSTALS
3.2 x 1.5 x 0.9mm Ultra-miniature 32.768kHz Crystal
Frequency 32.7680kHz
Ultra-miniature package: 3.2 x 1.5 x 0.75mm
Low mass, rugged construction
Packaged in standard EIA tape and reel
DESCRIPTION
EQ156 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. Their miniature size and rugged
construction make them ideal for battery powered, hand-held
equipment.
