Crystals Procurement Notes

Verify that the ordered part number exactly matches SX3B38.400F1010F30 to ensure correct frequency and package specifications. Confirm that the supplier provides documentation verifying the 30 Ohm ESR and 10 pF load capacitance values. Ensure storage conditions comply with manufacturer guidelines for surface-mount crystals to prevent degradation of solderability or frequency stability prior to assembly.

Crystals Selection Notes

Select this component when a 38.4 MHz fundamental frequency crystal is required for surface-mount applications. The 10 pF load capacitance must match the external circuit design requirements. Consider the 30 Ohm ESR limit for oscillator circuit drive level constraints. Verify that the ±10 ppm initial tolerance and ±30 ppm total stability meet the system's timing accuracy specifications.

Crystals Part Context

This component belongs to the SCTF SX3B series of surface-mount crystals. The series offers various frequencies and package options for general-purpose timing needs. The SX3B designation indicates a specific form factor within the manufacturer's portfolio, distinct from through-hole or other surface-mount variants like the SX1B series which may differ in ESR or package dimensions.

Crystals Replacement Considerations

Direct substitutes must maintain the 38.4 MHz frequency, 4-SMD no-lead package, 10 pF load capacitance, and ≤30 Ohm ESR. Verify that alternative manufacturers specify identical frequency tolerances and stability ratings. Cross-reference pinout and footprint dimensions to ensure mechanical compatibility without PCB redesign.
