Crystals Procurement Notes

Verify the specific suffix 'S' against the official CTS datasheet to confirm the exact package dimensions and lead-free plating specifications. Ensure the ordering quantity aligns with the manufacturer's standard reel packaging requirements. Confirm that the application circuit matches the specified 20pF load capacitance for accurate frequency calibration. Cross-reference the ESR value with the target oscillator circuit design to guarantee stable startup conditions.

Crystals Selection Notes

Select this component when a 16 MHz fundamental crystal is required in a compact 2.5x2 mm footprint. The ±30 ppm tolerance suits general-purpose digital logic and communication interfaces. Consider the 40 Ohm ESR relative to the driving circuit capabilities. This part is suitable for designs requiring RoHS3 compliance and industrial temperature resilience without needing high-precision automotive certification.

Crystals Part Context

This part belongs to the CTS 406 Series of surface-mount crystals. The series offers various frequencies and package sizes optimized for space-constrained electronics. The 406C35S16M00000 specifically addresses the need for a standard 16 MHz reference in modern SMD-based PCB layouts, balancing size, cost, and performance for non-critical timing applications.

Crystals Replacement Considerations

Direct substitutes within the same series include other 16 MHz variants from CTS-Frequency Controls with compatible packages. Verify pinout compatibility and electrical parameters before swapping. Generic replacements must match the 20pF load capacitance and 40 Ohm ESR to maintain circuit stability.
