Crystals Procurement Notes

Verify the specific suffix 'CDR' to ensure correct packaging configuration, as ordering suffixes determine tape and reel specifications rather than electrical function. Confirm that the required load capacitance matches the target circuit design parameters before procurement. Ensure compatibility with standard reflow soldering profiles for SMD components.

Crystals Selection Notes

Select this component when a 54 MHz fundamental crystal with ±10ppm stability is required in a small form factor. Consider the 60 Ohm ESR value for oscillator circuit loading calculations. Verify that the -20°C to +70°C operating range meets the application's thermal requirements compared to wider industrial temperature options.
