Crystals Procurement Notes

Verify current availability status as the part may be discontinued or limited in stock. Confirm that the 18 pF load capacitance matches the target circuit design requirements. Ensure the ±10 ppm stability meets system precision needs. Check for RoHS3 compliance if required by project specifications. Validate package dimensions against PCB footprint constraints before procurement.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency with 18 pF load capacitance is required. Consider the 60 Ohm ESR value for oscillator circuit compatibility. Evaluate the -20°C to +70°C temperature range against operational environments. Compare physical size constraints with alternative packages if space is limited. Assess frequency stability requirements against the ±10 ppm specification.
