Crystals Procurement Notes

Verify the specific suffix and packaging configuration when ordering, as availability may vary between cut tape, reel, or mouse reel formats. Confirm that the required frequency tolerance and temperature range align with the target application's environmental constraints before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 30 MHz fundamental mode crystal is required with moderate stability specifications. Ensure the circuit design accommodates the specified 18 pF load capacitance and 60 Ohm ESR to achieve optimal oscillator performance. Compare against higher stability variants if tighter ppm tolerances are necessary for the system.

Crystals Part Context

This part belongs to the 7M series of quartz crystals from TXC Corporation, which focuses on general-purpose surface-mount resonators. The series offers various frequency options within a standardized small footprint, allowing designers to maintain consistent board layout practices across different product lines while varying only the frequency parameters.

Crystals Replacement Considerations

Direct substitutes include other 30 MHz SMD crystals with matching 18 pF load capacitance and similar physical dimensions. Verify that any alternative component meets the same ±30 ppm stability and -20°C to +70°C operating temperature requirements to ensure functional compatibility.
