EUROQUARTZ LIMITED Blacknell Lane CREWKERNE Somerset UK TA18 7HE EURO QUARTZ X4115 SERIES CRYSTALS
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.
