Crystals Procurement Notes

Verify the specific datasheet version and mechanical dimensions against the target PCB footprint before integration. Confirm that the 4-SMD no-lead package compatibility aligns with the manufacturing equipment capabilities. Ensure the ±10ppm tolerance meets the system timing requirements. Check for any RoHS compliance documentation if required by the end product regulations.

Crystals Selection Notes

Select this component when a 40 MHz quartz crystal with ±10ppm stability is required in a small surface-mount form factor. Consider the 10pF load capacitance to ensure proper oscillator circuit tuning. Evaluate the 50 Ohm ESR against the driving capability of the host oscillator IC. This part is suitable for general-purpose frequency control where moderate stability suffices.
