Crystals Procurement Notes

Verify the specific suffix DD17 against official Suntsu documentation to confirm exact stability and temperature ratings. Ensure the required load capacitance matches the target circuit design. Confirm package dimensions align with PCB layout constraints. Request current datasheets for updated electrical characteristics before finalizing procurement specifications.

Crystals Selection Notes

Select this component when a 26 MHz fundamental frequency is required with ±20 ppm stability. The 18 pF load capacitance must match the oscillator circuit requirements. Consider the -10°C to +70°C operating range for environmental suitability. Evaluate the 100 Ohm ESR against driver strength limitations. Compare physical dimensions of the 4-SMD package against available board space.

Crystals Part Context

This part belongs to the SXT214 series of surface-mount crystals from Suntsu Electronics. The series offers various frequency options and stability grades. The SXT21418DD17 variant specifically targets applications requiring moderate stability in compact electronic designs. It serves as a timing reference for digital logic and communication interfaces.

Crystals Replacement Considerations

Direct substitutes include other 26 MHz crystals with identical 18 pF load capacitance and 4-SMD No Lead packages. Verify that alternative parts meet or exceed the ±20 ppm stability and 100 Ohm ESR specifications. Check compatibility with existing oscillator circuit parameters before substitution.
