Crystals Procurement Notes

Verify the specific suffix designation against official Suntsu documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with target PCB footprint dimensions and soldering profiles. Cross-reference the load capacitance value with the host oscillator circuit design to guarantee proper frequency accuracy and startup reliability under operating conditions.

Crystals Selection Notes

Select this component for designs requiring robust EMI performance in compact form factors. The four-pad architecture offers superior grounding compared to standard two-lead crystals. Evaluate the 80 Ohm ESR against the microcontroller or oscillator IC drive level requirements. Confirm that the ±30 ppm tolerance aligns with system timing constraints for wireless protocols.

Crystals Part Context

This model belongs to the SXT224 series of ceramic surface-mount crystals. The series is characterized by small 2.5x2.0 mm footprints suitable for space-constrained portable electronics. The specific part number indicates a 24 MHz frequency variant within the broader product line offering various frequencies and tolerance grades.

Crystals Replacement Considerations

Direct substitutes must match the 24 MHz frequency, 18 pF load capacitance, and 4-SMD no-lead package. Verify equivalent ESR values and temperature range specifications. Alternative components from other manufacturers require validation of pinout compatibility and mechanical height restrictions.
