Crystals Procurement Notes

Verify the specific suffix EA16 against official Suntsu documentation to confirm exact stability and temperature ratings. Ensure the 18 pF load capacitance matches the target circuit design requirements. Cross-reference the 60 Ohm ESR specification with oscillator driver strength capabilities to prevent over-driving or failure to start.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency is required with moderate stability specifications. Consider the 18 pF load capacitance compatibility with the host oscillator circuit. Evaluate the -10°C to +60°C operating range against environmental conditions. Confirm the 4-SMD package fits the available PCB footprint constraints.

Crystals Part Context

This part belongs to the SXT214 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and stability options. The EA16 suffix typically denotes specific performance characteristics within this family. Compare with other variants like SXT21418CB27-26.000M for different frequency needs.

Crystals Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 18 pF load capacitance, and 4-SMD package. Verify that alternative components meet the ±50 ppm stability and 60 Ohm ESR requirements. Check for identical temperature range specifications to ensure environmental compatibility.
