Crystals Procurement Notes

Verify the complete part number including suffix CKR to ensure correct packaging configuration. Confirm that the required load capacitance matches the target circuit design specifications. Check datasheet for moisture sensitivity level handling requirements during storage and reflow soldering processes to maintain component integrity.

Crystals Selection Notes

Select this component when a 40MHz fundamental frequency crystal is required in a small SMD footprint. Ensure the application environment stays within the specified -20°C to +70°C operational range. Verify that the circuit's load capacitance aligns with the 8pF specification to achieve accurate frequency output without additional trimming adjustments.

Crystals Part Context

This part belongs to the CTS 402F series of surface-mount crystals. It shares the same form factor as other members in the family but differs in frequency and electrical parameters. The series provides various options for different clock speeds while maintaining consistent mechanical dimensions for board layout flexibility across product lines.

Crystals Replacement Considerations

Direct substitutes must match the 40MHz frequency, 8pF load capacitance, and 4-SMD 2.0x1.6mm package. Verify ESR compatibility and temperature range alignment before substitution.
