Crystals Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm exact tolerance and stability grades. Ensure the ordering part number matches the required load capacitance and ESR specifications for your circuit design. Confirm RoHS compliance status if restricted substances are a project constraint. Cross-reference the package dimensions with your PCB footprint library to ensure mechanical compatibility before finalizing procurement.

Crystals Selection Notes

Select this component when space constraints require a 2.5mm x 2.0mm footprint but electromagnetic interference immunity is critical. The four-pad layout offers superior noise rejection compared to standard two-pin crystals. Choose this model for applications demanding fundamental frequency operation to reduce circuit complexity. Verify that the 80 Ohm ESR limit aligns with your oscillator circuit's drive level requirements to prevent overdriving.
