Crystals Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm exact tolerance, load capacitance, and ESR specifications. Ensure the ordering part number matches the required frequency stability and package type for your PCB layout. Cross-reference the RoHS status and material composition if environmental compliance is mandatory for your project requirements.

Crystals Selection Notes

Select this component when space constraints require a 2520 footprint but electromagnetic compatibility is critical due to the four-pad grounded design. It is suitable for applications requiring stable 12MHz timing without complex impedance matching networks. Consider the ±20ppm stability limit for Bluetooth and Zigbee protocols where moderate frequency drift is acceptable.

Crystals Part Context

This model belongs to the SXT224 series of ceramic surface-mount crystals from Suntsu Electronics. The series is engineered for miniaturized wireless electronics, offering a balance between small form factor and electrical robustness. The 4-pad configuration distinguishes it from standard 2-pin variants by providing superior noise immunity for sensitive RF circuits.

Crystals Replacement Considerations

Direct substitutes include other SXT224 series variants with different load capacitances or tolerances, such as SXT22418FD48-12.000M. Verify pin compatibility and electrical parameters before swapping to ensure circuit integrity.
