Crystals Procurement Notes

Verify the specific ordering suffix against official Suntsu documentation to confirm exact frequency stability and temperature range specifications. Ensure the selected variant matches the required load capacitance and ESR values for the target oscillator circuit design. Cross-reference the part number with authorized distributors to confirm current availability and authenticity before finalizing procurement orders.

Crystals Selection Notes

Select this component when a compact 3225 footprint is required alongside improved noise immunity provided by the four-pad ground structure. Consider the -10°C to +60°C operational range suitability for the intended environment. Evaluate the ±20 ppm stability requirement against system timing constraints. Confirm compatibility with the host circuit's load capacitance requirements to ensure accurate frequency generation without external trimming.

Crystals Part Context

This model belongs to the SXT324 series, which specializes in small-form-factor industrial-grade crystals. The series differentiates itself through enhanced grounding capabilities inherent to the four-pad layout. It targets applications where space constraints and signal integrity are critical priorities, offering a reliable alternative to larger or less robust packaging technologies in modern electronic assemblies.

Crystals Replacement Considerations

Direct substitutes must match the 3225 footprint, 20 MHz frequency, 18 pF load capacitance, and similar stability ratings. Verify that any replacement maintains the four-pad configuration for equivalent grounding performance. Check if alternative manufacturers offer comparable temperature ranges and ESR values to ensure seamless integration into existing designs without circuit modification.
