Crystals Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to ensure correct load capacitance and tolerance ratings. Confirm RoHS compliance status through current datasheets as regulatory requirements may evolve. Validate physical dimensions against PCB footprint libraries prior to procurement to prevent mechanical interference during assembly processes.

Crystals Selection Notes

Select this component when a fundamental parallel resonant crystal is required for 8 MHz applications. Ensure the circuit design accommodates the specified 18 pF load capacitance to maintain frequency accuracy. Verify that the driving circuitry limits power consumption to the rated 100 µW to prevent frequency drift or damage to the quartz element during operation.

Crystals Part Context

This part belongs to the C5S series of surface-mount crystals from Aker Technology Corp. The series offers various frequency options and package sizes optimized for modern electronics manufacturing. The C5S designation indicates a standard size surface-mount configuration suitable for high-volume production environments requiring reliable timing components.

Crystals Replacement Considerations

Direct replacements must match the 8.000 MHz frequency, 18 pF load capacitance, and 4-pin SMD form factor. Cross-reference with other manufacturers' 3225-sized crystals ensuring identical electrical parameters and mounting compatibility.
