Crystals Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical parameters, as variations exist within the 402F204 series. Confirm availability status directly with authorized distributors, as supply conditions may change. Ensure the selected variant matches the required load capacitance and tolerance specifications for the target application circuit design.

Crystals Selection Notes

Select this component when a 20.48 MHz reference with 8 pF load capacitance is required. Compare ESR values and stability requirements against system specifications. Evaluate the 4-SMD package dimensions against PCB layout constraints. Consider alternative suffixes if different tolerances or packaging options are needed for the specific design implementation.
