4. Does not include calibration tolerance. The characteristics of the frequency stability over temperature
follow that of the AT thickness-shear mode.
5. 5 ppm MAX for frequencies 50 MHz and lower. For tighter tolerances and higher frequencies
contact factory.
6. Higher shock version available.
7. Per MIL-STD-202G, Method 204D, Condition D. Random vibration testing also available.
