Crystals Procurement Notes

Verify the specific datasheet version from Suntsu Electronics to confirm exact mechanical dimensions and soldering profiles. Ensure compatibility with reflow soldering temperatures specified in the official documentation. Check for any recent updates to the RoHS compliance status or material declarations before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 40 MHz reference with ±20 ppm stability is required in a small form factor. Consider the 12 pF load capacitance requirement for circuit matching. Evaluate the 50 Ohm ESR against the oscillator circuit design constraints. Compare against other series members if different frequencies or tolerances are needed.

Crystals Part Context

This part belongs to the SXT series of surface-mount crystals from Suntsu Electronics. It shares the same package type with variants offering different frequencies such as 24 MHz or 26 MHz. The numbering convention indicates specific electrical and mechanical characteristics unique to this model within the broader product family.

Crystals Replacement Considerations

Direct substitutes may include other 40 MHz crystals with identical 12 pF load capacitance and similar ESR values. Verify pinout compatibility for the 4-SMD No Lead package. Cross-reference with Suntsu's own series for alternative frequencies if system requirements allow modification.
