Crystals Procurement Notes

Verify the specific suffix AA16 against official Suntsu documentation to confirm temperature range and stability specifications. Ensure the required load capacitance matches the target circuit design. Confirm package compatibility with PCB footprint requirements before procurement.

Crystals Selection Notes

Select this component for applications requiring a 40 MHz reference with ±50 ppm stability. Consider the 18 pF load capacitance requirement for circuit tuning. Evaluate the 100 Ohm ESR against driver strength limitations. Verify the -40°C to +85°C range meets environmental constraints.

Crystals Part Context

This part belongs to the SXT214 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and packages. The AA16 suffix typically denotes specific electrical and thermal characteristics within this family. Compare with other SXT214 variants for different frequency or package needs.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz crystals with identical 18 pF load capacitance and 4-SMD no-lead packaging. Verify pinout and dimensional compatibility. Check if alternative manufacturers offer equivalent ±50 ppm stability and ESR values.
