PACKAGING OPTIONS
3. Does not include calibration tolerance. The characteristics of the frequency stability over
temperature follow that of the AT thickness-shear mode.
4. 5 ppm MAX for frequencies below 40 MHz. For tighter tolerances and higher frequencies
contact factory.
5. Higher shock version available. Refer to data sheet model CX1HGSM AT (10108).
6. Per MIL-STD-202G, Method 204D, Condition D. Random vibration testing also available.
