Crystals Procurement Notes

Verify the specific lot date code and packaging configuration upon receipt to ensure compliance with storage and handling requirements. Confirm that the received components match the ordered part number exactly, paying attention to any suffix variations that may indicate different tolerances or specifications. Ensure proper ESD precautions are maintained during inspection and installation.

Crystals Selection Notes

Select this component when a 27 MHz reference signal is required in a space-constrained application. The 18 pF load capacitance must align with the host circuit's design parameters to ensure accurate frequency generation. Consider the ±30 ppm stability requirement against the system's timing sensitivity needs before finalizing the selection.

Crystals Part Context

This part belongs to the SXT214 series of surface-mount crystals from Suntsu Electronics. The series offers various frequency options within a standardized 4-SMD footprint. The DB38 suffix typically denotes specific electrical characteristics within this family, distinguishing it from other variants like CB27 or ED38 which may have different stability or tolerance ratings.

Crystals Replacement Considerations

Direct replacements must maintain the 27 MHz frequency, 18 pF load capacitance, and 4-SMD package dimensions. Verify that substitute components meet or exceed the ±30 ppm stability and 100 Ohm ESR specifications to ensure circuit compatibility without modification.
