• High-density industrial control systems

Crystals Procurement Notes

Verify the specific suffix 'DD17' against the manufacturer's current datasheet to confirm pinout compatibility and soldering profile requirements. Ensure the selected variant matches the required ±20ppm stability specification for the target application. Cross-reference the 4-SMD no-lead package dimensions with PCB footprint libraries to prevent assembly errors during production.

Crystals Selection Notes

Select this component when space constraints necessitate a 2520 footprint but electromagnetic interference immunity is critical. The four-terminal structure offers superior EMI reduction compared to standard two-lead crystals. Consider the ±20ppm tolerance sufficient for general wireless protocols while evaluating if tighter tolerances are needed for precise timing synchronization tasks.

Crystals Part Context

This part belongs to the SXT224 series of ceramic surface-mount crystals from Suntsu Electronics. The series is engineered for compact wireless devices requiring stable frequency references. The 2520 package size balances miniaturization with electrical performance, targeting modern portable electronics and IoT sensors where board real estate is limited.

Crystals Replacement Considerations

Direct substitutes must match the 14.7456 MHz frequency, 20pF load capacitance, and 4-SMD package. Verify that alternative sources provide identical ±20ppm stability and compatible ESR values to maintain oscillator circuit reliability without redesign.
