Crystals Procurement Notes

Verify the exact operating temperature range specified in the official datasheet, as conflicting data exists between -40°C to +85°C and 0°C to +70°C across different sources. Confirm the package type matches the HC-49/US designation or SMD variant required for your PCB layout. Ensure the load capacitance requirement aligns with your circuit design before procurement.

Crystals Selection Notes

Select this component when a 27 MHz surface-mount crystal with ±30 ppm stability is required. Consider the 18 pF load capacitance compatibility with your oscillator circuit. Evaluate the physical dimensions against available board space. Compare ESR specifications if driving capability is critical for the application.
