Crystals Procurement Notes

Verify the specific suffix 'D' against the manufacturer's latest datasheet to confirm the 18pF load capacitance specification, as variations exist within the series. Ensure the ordering documentation explicitly matches the full part number 405C35D08M00000 to avoid confusion with similar 20pF variants like the 406C35E series. Confirm package dimensions align with PCB footprint requirements prior to procurement.

Crystals Selection Notes

Select this component when an 8 MHz fundamental frequency is required with moderate stability specifications suitable for general digital applications. The 18pF load capacitance must match the oscillator circuit design. Consider the 4-SMD package size for space-constrained layouts. Evaluate the -20°C to +70°C temperature range against environmental conditions to ensure operational reliability without requiring extended grade components.

Crystals Part Context

This part belongs to the CTS 405 Series of surface-mount crystals, designed for cost-effective frequency control in consumer and industrial electronics. The series utilizes standard AT-cut quartz technology optimized for mass production. The 405C35D08M00000 represents a specific configuration within this family, balancing performance metrics with standard SMD packaging constraints for widespread integration.

Crystals Replacement Considerations

Direct substitutes include other 8 MHz crystals with identical 18pF load capacitance and 4-SMD footprint. Verify ESR compatibility to ensure oscillator startup reliability. Cross-reference pinout and dimensional tolerances to guarantee mechanical fit. Alternative parts must maintain equivalent frequency tolerance and stability ratings for functional equivalence.
