Crystals Procurement Notes

Verify the specific suffix 'S' against official CTS documentation to confirm functional differences from standard variants like 'D' or 'E'. Ensure the required load capacitance matches the circuit design. Confirm RoHS3 compliance requirements are met for the target application environment. Check lead-free soldering profiles compatible with the specified package dimensions.

Crystals Selection Notes

Select this component when a precise 19.6608 MHz frequency is required for digital logic timing. The 20pF load capacitance must align with the oscillator circuit's parasitic capacitance. Consider the ±30ppm tolerance for system synchronization accuracy. The 4-SMD footprint suits automated assembly processes requiring space-constrained layouts.

Crystals Part Context

This part belongs to the CTS 406 Series of surface-mount crystals. It shares the same physical dimensions and electrical characteristics as other variants within the series, differing primarily in packaging suffixes or specific calibration tolerances. The series is designed for general-purpose timing applications in consumer and industrial electronics.
