Crystals Procurement Notes

Verify the specific suffix 'S' against official datasheets to confirm package dimensions and sealing integrity, as variations exist within the 406 series. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability. Confirm that the hermetic seal meets project requirements for harsh environments. Validate RoHS compliance status through current documentation before integration.

Crystals Selection Notes

Select this component when hermetic sealing is required for surface mount quartz crystals. The 406 series offers larger physical dimensions compared to standard SMD crystals, providing robustness. Ensure the 20 pF load capacitance matches the oscillator circuit design. Verify that the 80 Ohm ESR is compatible with the driving level specifications of the target application.

Crystals Part Context

This part belongs to the CTS 406 series of surface mount quartz crystals. The series is characterized by hermetic ceramic packages suitable for demanding environments. It provides fundamental mode operation with high frequency stability. The 406 series is distinct from the smaller 403 and 405 series due to its larger footprint and sealed construction.

Crystals Replacement Considerations

Direct substitutes include other hermetic 406 series crystals with identical electrical parameters. Verify package compatibility if space is constrained. Alternative non-hermetic options require circuit re-evaluation for environmental protection.
