Crystals Procurement Notes

Verify the specific suffix ILR against the manufacturer's current datasheet to confirm package and tape specifications. Confirm that the ±20 ppm tolerance aligns with the target application's timing requirements. Check for updated lead times as availability may vary. Ensure the 12 pF load capacitance matches the oscillator circuit design parameters before finalizing procurement.

Crystals Selection Notes

Select this component when a 40 MHz fundamental crystal with ±20 ppm stability is required. The 60 Ohm ESR must be compatible with the driving circuit's power constraints. The 4-SMD footprint requires appropriate PCB land pattern design. Consider the -40°C to +85°C temperature range against environmental conditions. Verify compatibility with standard SMD reflow profiles during manufacturing integration.
