Crystals Procurement Notes

Verify the exact load capacitance and ESR specifications against the official datasheet before integration, as these parameters are critical for oscillator circuit stability. Ensure that the PCB footprint matches the four-terminal no-lead SMD package dimensions provided in the manufacturer's documentation to prevent soldering defects. Confirm compliance with RoHS standards if required by your supply chain regulations.

Crystals Selection Notes

Select this component when a 16.384 MHz frequency is specifically required for digital logic timing or serial communication baud rates. The 18 pF load capacitance must match the external capacitors used in the oscillator circuit to achieve the specified frequency accuracy. Consider the ±15 ppm stability requirement relative to the system's tolerance needs, and ensure the 200 Ohm ESR limit is compatible with the driving circuit's capabilities.

Crystals Part Context

This part belongs to the SXT21418EB series of surface-mount crystals from Suntsu Electronics, Inc. The series offers various frequencies and stability options within a standardized small form factor.
