Crystals Procurement Notes

Verify the specific suffix 'C' against official documentation to confirm the -40°C to +85°C industrial temperature rating, as variations exist within the 406 series. Ensure the 13pF load capacitance matches the target circuit design requirements. Confirm RoHS3 compliance status through the manufacturer's current environmental declarations before finalizing procurement specifications.

Crystals Selection Notes

Select this component when a 20.48 MHz reference is required for high-density surface-mount layouts. The 40-Ohm ESR value must be validated against the oscillator circuit's drive level constraints to prevent over-driving the crystal. Consider the 6.00mm x 3.50mm footprint availability during PCB layout planning to ensure adequate spacing and soldering reliability.
