Crystals Procurement Notes

Verify the specific suffix 'D' against the official CTS datasheet to confirm the exact load capacitance and temperature grade, as ordering suffixes define critical electrical parameters. Ensure the design-in process accounts for the 13 pF load requirement to maintain the specified ±30 ppm tolerance. Cross-reference the 406 series mechanical dimensions with the PCB footprint library to prevent soldering defects during reflow processes.

Crystals Selection Notes

Select this component when a 14.31818 MHz reference is required for industrial applications demanding extended temperature performance. The 406 series offers a balance of size and stability suitable for space-constrained designs. Compare the 60 Ohm ESR limit against the oscillator circuit drive level specifications to ensure stable startup and avoid overdriving the crystal element during operation.
