Description
KEY FEATURES
Temperature pensation Small SMD ceramic package Low power consumption of 6µA Tri state output
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
