Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact electrical tolerances and temperature ratings. Ensure compatibility with the target PCB footprint and reflow soldering profile. Confirm RoHS compliance status if required by project specifications, as availability may vary by production batch. Cross-reference part numbers carefully to avoid substitution errors.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency is required in a surface-mount format. Consider the 16 pF load capacitance requirement for oscillator circuit design. Evaluate the ±50 ppm stability against system timing requirements. The HC49S package size must fit within the available board space constraints.
