Crystals Procurement Notes

Verify the specific suffix 'CKR' against official datasheets to confirm lead frame material and plating specifications, as these variants may differ from standard 'CDT' or 'IDR' packages. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into PCB assembly workflows to ensure supply chain compatibility.

Crystals Selection Notes

Select this component when an 8 pF load capacitance is required for the target circuit design. Ensure the operating environment remains within the specified -20°C to +70°C range. Verify that the 100 Ohm ESR aligns with the oscillator circuit's drive level constraints to prevent frequency instability or crystal damage during operation.
