Crystals Procurement Notes

Verify the specific ordering suffix and package variant against the official Suntsu Electronics datasheet before purchase. Confirm that the load capacitance and ESR values match the target circuit design requirements. Ensure the operating temperature range aligns with the intended application environment. Request the latest manufacturing documentation to validate compliance with current industry standards and material specifications.

Crystals Selection Notes

Select this component when a 38.4 MHz reference signal is required with moderate stability. Consider the 9 pF load capacitance compatibility with the host oscillator circuit. Evaluate the 60 Ohm ESR against the drive level limitations of the connected system. Assess the 4-SMD footprint availability on the printed circuit board layout prior to finalizing the design.

Crystals Part Context

This part belongs to the SXT2249 series of surface-mount crystals from Suntsu Electronics. The series offers various frequency options within a standardized small form factor.
