Crystals Procurement Notes

Verify the specific suffix AA07 against official Suntsu documentation to confirm exact electrical tolerances and temperature ratings. Ensure the required load capacitance matches the circuit design. Confirm RoHS compliance status through current datasheets as specifications may evolve. Cross-reference the manufacturer part number to avoid confusion with similar series variants that may have different stability or packaging requirements.

Crystals Selection Notes

Select this component when a 16.384 MHz reference is required with ±50 ppm stability over an extended industrial temperature range. The 18 pF load capacitance must align with the oscillator circuit design. Consider the 4-SMD package dimensions for PCB layout constraints. Evaluate ESR limits against oscillator drive level specifications to ensure reliable startup and operation without overdriving the crystal.

Crystals Part Context

This part belongs to the SXT224 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and stability options in a standardized small outline package. The SXT22418AA07-16.384M specifically targets applications requiring precise timing at 16.384 MHz with robust performance across industrial thermal conditions.

Crystals Replacement Considerations

Direct substitutes include other SXT224 series parts with identical 16.384 MHz frequency, 18 pF load capacitance, and 4-SMD footprint.
