1) Other tolerances available. Contact factory.
2) Does not include calibration tolerance. The characteristics of the frequency stability over
temperature follow that of the AT thickness-shear mode.
SUGGESTED LAND PATTERN
3) 5 ppm MAX for frequencies below 40 MHz. For tighter tolerances and higher frequencies
contact factory.
4) Higher shock version available.
5) Per MIL-STD-202G, Method 204D, Condition D. Random vibration testing also available.
