Crystals Procurement Notes

Verify the specific suffix 'S' against the official CTS datasheet to confirm environmental ratings and material composition. Ensure the selected variant matches the required load capacitance and ESR specifications for the target application circuit. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Crystals Selection Notes

Select this component when a standard 18.432 MHz reference is required in a small form factor. The 13 pF load capacitance must align with the oscillator circuit design. Consider the ±50 ppm stability requirement relative to system timing accuracy needs. Verify compatibility with reflow soldering profiles specified for the 4-SMD package.

Crystals Part Context

This part belongs to the CTS 406 series of surface-mount crystals. The series provides various frequencies and package sizes for general-purpose timing applications. The 406I35S18M43200 specifically addresses the common 18.432 MHz requirement used in serial communication and digital logic interfaces.

Crystals Replacement Considerations

Direct substitutes include other 18.432 MHz SMD crystals with matching 13 pF load capacitance and similar physical dimensions. Verify that alternative parts meet the same ±30 ppm tolerance and 40 Ohm ESR requirements to ensure circuit performance parity.
