Crystals Procurement Notes

Verify the complete part number including suffixes to ensure correct frequency tolerance and packaging specifications. Confirm that the supplier provides original manufacturer documentation or test reports to validate authenticity. Check RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure storage conditions meet humidity sensitivity levels before soldering to prevent moisture-induced damage during thermal cycling.

Crystals Selection Notes

Select this component when a 18.432 MHz reference frequency is required for synchronous digital logic. The 15 pF load capacitance must match the external circuit requirements to achieve accurate frequency output. Consider the ±20 ppm stability limit against system jitter requirements. The 4-SMD package size should fit within the available PCB footprint constraints compared to through-hole alternatives.

Crystals Part Context

This crystal belongs to Suntsu Electronics' SXT series of surface-mount resonators. These components are engineered for high-volume production environments where consistent electrical characteristics and mechanical reliability are critical. The series offers various frequency options and package sizes to support diverse embedded system architectures.

Crystals Replacement Considerations

Direct replacements include other 18.432 MHz crystals with identical 15 pF load capacitance and 4-SMD no-lead packages. Verify that substitute parts maintain the same ±20 ppm stability and 200 Ohm ESR limits to ensure circuit compatibility without redesign.
