DESCRIPTION
95SMX(G) crystals are miniature surface-mount crystals specifically
designed to provide a low-cost and reliable source of real time clock
frequency, 32.768kHz for mass-market applications, and also
frequencies in the range 30kHz to 100kHz. The parts are low-profile,
and of low mass. The package is encapsulated in epoxy resin.
