Crystals Procurement Notes

Verify that the specific part number matches the required load capacitance and frequency tolerance for your circuit design. Confirm the package dimensions align with your PCB footprint requirements. Ensure compliance with RoHS3 regulations if applicable to your manufacturing process. Check availability status as supply levels may vary. Request official datasheets to validate electrical parameters before integration.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for 40 MHz applications. Consider the 12 pF load capacitance requirement for oscillator circuit compatibility. Evaluate the ±30 ppm tolerance against system timing accuracy needs. The 60 Ohm ESR value should be compatible with the driving circuit's output impedance. Verify the -40°C to +85°C temperature range meets environmental specifications.
