Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact packaging configuration and compliance status. Ensure the selected variant matches the required load capacitance and frequency tolerance specifications for the target circuit design. Cross-reference the datasheet revision date to confirm current manufacturing parameters and availability constraints before finalizing procurement orders.

Selection Notes

Select this component when a 20 MHz fundamental frequency with tight ±20 ppm tolerance is required for precision timing applications. The 18 pF load capacitance must align with the host oscillator circuit requirements. Consider the 40 Ohm ESR and 100 uW drive level limits to ensure reliable operation within the specified -40°C to +85°C industrial temperature range without exceeding electrical stress limits.
