Crystals Procurement Notes

Verify the specific lot code and date code upon receipt to ensure compliance with RoHS standards. Confirm that the delivered quantity matches the purchase order exactly. Inspect the components for physical damage or contamination before soldering. Ensure storage conditions remain within specified humidity and temperature limits to maintain performance integrity until installation.

Crystals Selection Notes

Select this component when a 38.4 MHz frequency is required for space-constrained applications. The 8 pF load capacitance must match the circuit design requirements. Consider the ±30 ppm stability for precision timing needs. The 60 Ohm ESR should be compatible with the driving circuit's power constraints. Verify the -10°C to +60°C temperature range meets environmental specifications.

Crystals Part Context

This part belongs to the SXT224 series of surface-mount crystals from Suntsu Electronics. It shares the SMD2520-4P form factor with other variants in the lineup but differs in frequency and electrical parameters. The series is designed for high-volume manufacturing environments requiring consistent performance and reliable supply chain integration.

Crystals Replacement Considerations

Direct substitutes include SXT2248AA48-38.400M, which offers similar frequency but different stability ratings. Verify pin compatibility and electrical characteristics before swapping. Ensure the replacement maintains the same load capacitance and ESR values to prevent circuit malfunction.
