1. Other tolerances available. Contact factory . 2. Unless specified otherwise.
3. Crystals are characterized and tested at 50 µW, unless specified otherwise. Operation at higher drive levels can result in sub-optimal behavior . 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.
