EQUIVALENT CIRCUIT
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.
