Crystals Procurement Notes

Verify component authenticity through authorized channels as the part status indicates discontinuation at major distributors. Confirm that the specific suffix corresponds to the required 10pF load capacitance and 100 Ohm ESR specifications. Ensure compatibility with existing PCB footprints and reflow soldering profiles before integration into production lines.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency with 10pF load capacitance is required in a small form factor. Consider the ±20ppm stability for timing-critical applications. Evaluate the 100 Ohm ESR against oscillator circuit requirements to ensure proper startup and sustained oscillation within the specified temperature range.
