Crystals Procurement Notes

Verify the specific lot code and date code upon receipt to ensure recent manufacturing dates. Confirm that the received components match the exact part number SXT11412DA38-27.000M, as suffix variations may indicate different tolerances or packaging types. Ensure storage conditions comply with moisture sensitivity level requirements before soldering.

Crystals Selection Notes

Select this component when space constraints require a sub-0402 footprint size. Choose this model for applications demanding strict frequency stability over wide temperature ranges without active compensation. Consider the low ESR value for designs where minimal loading on the oscillator circuit is critical for performance.

Crystals Part Context

This part belongs to the SXT114 series of ultra-small crystals from Suntsu Electronics. The series is characterized by its 4-pad grounding structure, which provides superior interference rejection compared to traditional two-pad designs. The naming convention encodes the frequency tolerance, temperature range, and physical dimensions directly into the part number.

Crystals Replacement Considerations

Direct substitutes must maintain the 1.6x1.2mm 4-pad form factor and 27MHz frequency. Verify that alternative parts offer comparable ESR values below 150 Ohms to prevent cold-start issues. Ensure replacement components support the same -30°C to +85°C operating range for industrial compatibility.
