EUROQUARTZ LIMITED Blacknell Lane CREWKERNE Somerset UK TA18 7HE EURO QUARTZ 90SMX(N) CRYSTALS
DESCRIPTION
90SMX(N) crystals are miniature surface-mount crystals specifically designed to provide a low-cost and reliable source of real time clock 32.768kHz frequency fro mass-marlet applications. The crystals are low-profile and encapsulated in epoxy resin.
