Crystals Procurement Notes

Verify the specific lot code and date code upon receipt to ensure compliance with project timelines. Confirm that the delivered components match the exact SXT11412FC27-38.400M designation, as suffix variations may indicate different tolerances or packaging types. Request official datasheets from the manufacturer to validate electrical characteristics against current production batches before final integration.

Crystals Selection Notes

Select this component when a precise 38.4 MHz reference is required for space-constrained designs. The 4-SMD no-lead package offers improved solder joint reliability compared to traditional leaded crystals. Ensure the host circuit supports the 12pF load capacitance to maintain the specified ±10ppm accuracy. Consider thermal management requirements given the -20℃ to +70℃ operating range.

Crystals Part Context

This part belongs to Suntsu Electronics' SXT11412 series of surface-mount crystals. The FC27 suffix typically denotes specific dimensional and electrical characteristics within this family. It serves as a direct replacement for legacy through-hole crystals where board space is limited. The series is designed for high-volume manufacturing environments requiring consistent frequency performance.

Crystals Replacement Considerations

Direct substitutes must match the 38.4 MHz frequency, 12pF load capacitance, and 4-SMD no-lead footprint. Verify that alternative manufacturers offer comparable ±10ppm tolerance and similar ESR values to ensure circuit compatibility without redesigning the oscillator tank circuit.
