Crystals Procurement Notes

Verify the specific suffix 'CAR' against the official CTS datasheet to confirm lead frame material and plating specifications. Ensure the design-in load capacitance matches the 8pF requirement to maintain frequency accuracy. Confirm that the PCB footprint aligns with the 2.00mm x 1.60mm outline to prevent soldering defects.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency is required in a compact SMD form factor. Consider the 60 Ohm ESR limit for oscillator circuit compatibility. Evaluate the ±15ppm tolerance against system jitter requirements. Compare against the 402F400XXCJT variant if different load capacitance or packaging options are needed.
