Crystals Procurement Notes

Verify the specific suffix codes against official Suntsu documentation to confirm exact electrical tolerances and temperature ranges. Ensure that the procurement channel provides genuine components with traceable manufacturing batches. Cross-reference the package outline drawing with PCB footprints to guarantee mechanical fitment. Request updated datasheets to validate current production status and any potential lifecycle changes before finalizing supply agreements.

Crystals Selection Notes

Select this component when a 27 MHz reference signal is required within a 2.5x2.0mm footprint. Consider the 80 Ohm ESR value for oscillator circuit design to ensure adequate start-up margins. Evaluate the ±30 ppm stability against system timing requirements. The four-terminal configuration is advantageous for noise-sensitive RF environments where shielding is critical for compliance.

Crystals Part Context

This model belongs to the SXT224 series of ceramic surface-mount crystals from Suntsu Electronics. The series targets miniaturized electronics, offering various frequency options within the same physical envelope. Differentiation within the series arises from load capacitance values, stability grades, and specific application-oriented suffixes defined in the manufacturer's naming convention.

Crystals Replacement Considerations

Direct substitutes must match the 27 MHz frequency, 11 pF load capacitance, and 4-SMD no-lead package. Verify equivalent ESR and stability specifications to maintain circuit performance. Consult Suntsu's official cross-reference lists for validated replacements.
