Crystals Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm exact electrical tolerances and temperature ranges. Ensure compatibility with the target PCB footprint and soldering profile requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when a small 2520 form factor is required alongside enhanced EMI performance compared to standard two-pin variants. Consider the ±20 ppm stability sufficient for general-purpose timing applications where strict high-frequency precision is not mandated.

Crystals Part Context

This part belongs to the SXT224 series of industrial-grade ceramic crystals. The series is characterized by its AT-cut fundamental frequency design, which simplifies oscillator circuit requirements by eliminating the need for additional matching inductors often associated with overtone modes.

Crystals Replacement Considerations

Direct substitutes include other SXT224 series variants with different frequencies or load capacitances, such as SXT22421DD17-13.560M. Cross-model replacements from other manufacturers require careful verification of pinout, ESR, and drive level specifications.
