Crystals Procurement Notes

Verify the specific suffix configuration against the manufacturer's official datasheet to ensure compliance with required frequency tolerance and stability specifications. Confirm that the 406I35D40M00000 designation matches the intended load capacitance and ESR requirements for the target circuit design before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency is required with ±30 ppm initial tolerance. Ensure the application circuit supports an 18 pF load capacitance to maintain accuracy. Verify that the 6x3.5 mm footprint aligns with the available board space and that the 40 Ohm ESR is compatible with the oscillator driver circuit capabilities.

Crystals Part Context

This part belongs to the CTS 406 Series, which provides standard surface-mount quartz crystals designed for general-purpose timing applications. The series offers various frequency options within a compact form factor, catering to modern electronics that require reliable frequency references without occupying excessive board area.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz SMD crystals from CTS with identical 18 pF load capacitance and 6x3.5 mm dimensions. Cross-manufacturer replacements must match the 40 MHz frequency, 18 pF load, ±30 ppm tolerance, and physical footprint to ensure functional compatibility.
