Crystals Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure compatibility with required load capacitance and tolerance levels. Confirm that the 4-SMD no-lead package dimensions align with the target PCB land pattern. Check RoHS compliance status if environmental regulations apply to the end product. Ensure the operating temperature range meets the environmental requirements of the intended application environment before finalizing procurement.

Crystals Selection Notes

Select this component when a 18.432 MHz fundamental frequency is required for digital logic timing. The 13 pF load capacitance must match the oscillator circuit design parameters to achieve accurate frequency output. Consider the ±50 ppm tolerance limit for initial calibration accuracy needs. The surface-mount format is appropriate for high-volume manufacturing where space constraints are critical. Evaluate the ESR value to ensure it falls within the driving circuit's capability limits.
