Crystals Procurement Notes

Verify the specific suffix code associated with the XX placeholder to confirm exact frequency tolerance and stability ratings, as these parameters vary across the 402F400XXCDR product family. Ensure the selected variant matches the required load capacitance and operating temperature range for the target application environment before finalizing procurement orders.

Crystals Selection Notes

Select this component when a surface-mount crystal is required for 40 MHz applications with moderate stability needs. Consider the 18 pF load capacitance requirement for circuit matching and verify that the 60 Ohm ESR limit aligns with the oscillator circuit design constraints. Evaluate the -20°C to +70°C operating range against environmental conditions.
