Crystals Procurement Notes

Verify the specific suffix 'E' against the manufacturer's official datasheet to confirm that the electrical parameters match the required design specifications. Ensure the ordering documentation explicitly references part number 403C35E18M43200 to avoid confusion with similar variants in the 403 series. Cross-check the supplier's certificate of conformity for RoHS3 compliance prior to final procurement authorization.

Crystals Selection Notes

Select this component when a 18.432 MHz fundamental frequency is required with a 20pF load capacitance. The ±30 ppm tolerance suits general digital logic timing where high precision is not critical. Consider the 60 Ohm ESR value for oscillator circuit compatibility. The operating temperature range of -20°C to +70°C defines the suitable environmental limits for the application.

Crystals Part Context

This part belongs to the CTS 403 Series of surface-mount crystals. It shares the standard 4-SMD footprint dimensions common to this family but differs in specific electrical ratings defined by its unique model code. The series is characterized by lead-free construction and suitability for reflow soldering processes used in modern electronics manufacturing.

Crystals Replacement Considerations

Direct substitutes within the same series include 403C35D18M43200 or 403I35E18M43200. Verify that alternative part numbers maintain identical frequency, load capacitance, and physical dimensions before implementation.
