1. Other tolerances available. Contact factory.
2. Unless specified otherwise.
3. Does not include calibration tolerance. The characteristics of the frequency stability over
temperature follow that of the AT thickness-shear mode.
4. 10 ppm MAX for frequencies below 40 MHz. For tighter tolerances and higher
frequencies contact factory.
5. Higher shock version available.
6. Per MIL-STD-202G, Method 204D, Condition D. Random vibration testing also available.
