Crystals Procurement Notes

Verify the specific suffix 'CB27' against official datasheets to confirm exact ESR and load capacitance values, as variations exist within the SXT324 series. Ensure the required temperature range (-20℃ to +70℃) aligns with system operational requirements. Confirm RoHS compliance status matches current regulatory standards for the target market before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 18.432 MHz frequency is specifically required with ±25ppm tolerance. Consider the 70 Ohm ESR value for oscillator circuit compatibility. The 4-SMD package is appropriate for space-constrained PCB layouts. Verify that the ±30ppm stability meets the system's jitter and phase noise specifications compared to higher-stability alternatives.

Crystals Part Context

This part belongs to the SXT324 series of MHz crystals from Suntsu Electronics, Inc. The series offers various frequencies and packages, including 4-SMD configurations. The SXT32410CB27 variant specifically targets applications needing 10pF load capacitance. It is distinct from other series members like the SXT32418CA07 which may feature different capacitance or stability ratings.

Crystals Replacement Considerations

Direct substitutes include other SXT32410 variants with identical 18.432 MHz frequency and 10pF load capacitance, such as SXT32410CB16-18.432M, provided ESR and package compatibility are verified. Cross-reference with generic 18.432 MHz 4-SMD crystals only if electrical parameters match exactly.
