Crystals Procurement Notes

Verify the specific suffix 'D' against official CTS documentation to confirm exact load capacitance and stability specifications, as variations exist within the 406 series. Ensure compatibility with reflow soldering profiles suitable for leadless SMD packages. Cross-reference the manufacturer part number with authorized distributors to confirm current production status and RoHS compliance details before procurement.

Crystals Selection Notes

Select this component when a 14.31818 MHz reference is required in space-constrained designs utilizing 6x3.5 mm footprints. Consider the ±30 ppm tolerance and 60 Ohm ESR for oscillator circuit design. Evaluate the -20°C to +70°C operating range against environmental conditions. Compare against alternative series like 405 or 406I if tighter stability or wider temperature ranges are necessary.

Crystals Part Context

This part belongs to the CTS 406 Series of surface-mount crystals, designed for general-purpose timing applications. It utilizes standard AT-cut quartz technology housed in a small outline package. The series offers a balance of performance and size, targeting consumer electronics and industrial control systems where moderate stability and cost-effectiveness are prioritized over high-precision requirements.
