The Geyer Electronic 12.87159 is a 32.768 kHz tuning fork crystal designed for surface mount applications. It features a load capacitance of 12.5 pF, a frequency tolerance of ±20 ppm at 25°C, and a typical frequency stability of -0.035 ppm/°C² over the operating temperature range of -40°C to +85°C. The crystal has a maximum equivalent series resistance of 50 kΩ and operates in fundamental mode.
This crystal is housed in a compact 2-SMD, no lead package measuring 3.20 mm x 1.50 mm x 0.80 mm, making it suitable for space-constrained designs. It is supplied on 180 mm reels with a standard quantity of 3000 pieces per reel. The part is recommended for use in Intel 8/C220-series and PCH-LP chipsets.
Additional electrical characteristics include a motional capacitance of 0.0036 pF, shunt capacitance of 1.3 pF, a maximum drive level of 1.0 µW, and a minimum quality factor of 20000. The aging rate is ±3 ppm in the first year at 25°C.
The frequency is 32.768 kHz.
The load capacitance is 12.5 pF.
The operating temperature range is -40°C to +85°C.
The package is 2-SMD, no lead, measuring 3.20 mm x 1.50 mm x 0.80 mm.
The frequency tolerance is ±20 ppm at 25°C.
The maximum ESR is 50 kΩ.
The part is listed as RoHS3 Compliant, but this is unverified.
