Crystals Procurement Notes

Verify the specific suffix 'BA16' against official Suntsu datasheets to confirm package dimensions and pinout compatibility. Ensure the required load capacitance matches the target circuit design specifications. Confirm RoHS compliance status through current manufacturer documentation rather than distributor summaries. Validate the operating temperature range requirements against the -30°C to +85°C specification before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 40 MHz surface-mount crystal with ±30 ppm accuracy is required for industrial applications. Consider the 7 pF load capacitance requirement to ensure proper circuit tuning. Evaluate the 4-SMD package size constraints against available PCB real estate. Compare ESR values of 50 Ohms against driver capability limits to prevent oscillation failure or excessive power consumption in the host circuit design.

Crystals Part Context

This part belongs to the SXT2247 series of surface-mount crystals from Suntsu Electronics. The series offers various frequency options including 38.4 MHz and 48 MHz variants. These components are engineered for compact electronic designs requiring stable frequency references. The BA16 designation indicates specific physical packaging characteristics distinct from other series members like the SXT22410EB17.

Crystals Replacement Considerations

Direct substitutes include the SXT2247AA38-40.000M, which shares the 40 MHz frequency but differs in tolerance specifications. Verify package compatibility when considering alternative manufacturers. Cross-reference load capacitance and ESR values to ensure electrical equivalence. Check for updated RoHS compliance declarations if replacing older inventory batches.
