Crystals Procurement Notes

Verify the specific suffix (e.g., DG or T) against official Suntsu documentation to confirm exact temperature range and reel specifications. Ensure the ordering part number matches the required load capacitance and tolerance. Cross-reference datasheets for precise storage conditions and soldering profiles to maintain component integrity during assembly.

Crystals Selection Notes

Select this component when a stable 28.63636 MHz reference is required in a small form factor. Consider the ±25 ppm tolerance for applications sensitive to frequency drift. Evaluate the 21 pF load capacitance compatibility with the target microcontroller or oscillator circuit input requirements before finalizing the design.

Crystals Part Context

This model belongs to Suntsu's SXT series of surface-mount crystals. The series typically utilizes ceramic packages designed for automated pick-and-place assembly. These components are engineered to provide consistent performance across various consumer and industrial electronic applications requiring precise timing signals.

Crystals Replacement Considerations

Direct substitutes must match the 28.63636 MHz frequency, 21 pF load capacitance, and 3.2x2.5mm package dimensions. Verify equivalent ESR and tolerance ratings from alternative manufacturers to ensure circuit stability without modification.
