Store the reels dry: the 4-SMD no-lead exposed-pad package is moisture-sensitive; a bake before reflow may be required if the moisture-barrier bag is compromised or the shelf life in the bag has been exceeded.
Package and temperature grade — board-fit notes
4-SMD, no-lead exposed-pad package, 7.00 mm x 5.00 mm body, 0.90 mm seated height. Supply current is 4 mA typ at 54 MHz — the MEMS resonator draws less than a comparable quartz oscillator at the same frequency, which matters in a thermally constrained enclosure where every milliwatt adds to the internal temperature rise.
