Description
EM7602 is a low power, low frequency crystal oscillator, with a three
times better thermal drift than any conventional tuning fork crystal.
It consists of a torsional tuning fork crystal and a CMOS integrated
circuit, both assembled in the same package. It is ideal for applications
requiring a high timekeeping accuracy over full temperature range.
The oscillator are supplied in trays (91 oscillators per tray).
For pick-and-place equipment, the parts are available in 16mm tapes:
7” (178 mm) reel with 1000 oscillators
10” (254 mm) reel with 2000 oscillators
13” (330 mm) reel with 4000 oscillators
