Crystals Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm exact electrical tolerances and packaging configurations. Ensure that the selected variant matches the required load capacitance and frequency stability specifications for the target circuit design before finalizing procurement orders.

Crystals Selection Notes

Select this component when space constraints require a 2.5x2.0 mm footprint alongside strict electromagnetic compatibility requirements. The four-terminal design is optimal for reducing radiated emissions in 2.4 GHz wireless environments where standard two-pin crystals may fail EMC testing.

Crystals Part Context

This part belongs to the SXT224 series of industrial-grade ceramic surface-mount crystals. The series is characterized by its compact 2520 package dimensions and robust construction suitable for demanding electronic applications requiring high reliability and consistent frequency performance over varying environmental conditions.

Crystals Replacement Considerations

Direct substitutes within the same series include variants such as SXT2249DA48-16.000M or SXT22418EE48-16.000M, provided they match the required frequency tolerance and load capacitance parameters. Verify pinout compatibility and thermal ratings before substitution.
