DESCRIPTION:
This very small SMD ceramic package has been specially designed to
combine the 32.768 kHz crystal unit with the CMOS-based oscillator circuit.
Ultra Low Power consumption, as low as 300 nA, are made possible
through 32.768 kHz Tuning-Fork-Crystals and sophisticated CMOScircuitry.
For pick-and-place equipment, the parts are available in 12 mm tape:
7” (178 mm) reel with 1'000 oscillators
7” (178 mm) reel with 3'000 oscillators
