Crystals Procurement Notes

Verify the specific manufacturer designation Shenzhen SCTF Electronics against the physical marking on the component to ensure authenticity. Confirm that the 4-SMD footprint matches the target PCB layout dimensions. Ensure the load capacitance requirement aligns with the host circuit's oscillator design specifications before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 40 MHz reference signal is required for industrial-grade applications. The ±30 ppm stability rating suits general timing needs where high precision is not critical. The SMD package facilitates efficient placement in space-constrained designs. Evaluate thermal requirements to ensure operation remains within the specified -40°C to +85°C limits.

Crystals Part Context

This part belongs to the SCTF S-X3CY series of surface-mount crystals. The series provides standard frequency options for embedded timing applications. The model number encodes the frequency, tolerance, load capacitance, and ESR values. It serves as a passive frequency control element in digital logic and communication circuits.

Crystals Replacement Considerations

Cross-reference with other 40 MHz SMD crystals from the same manufacturer family. Verify identical pinout and mechanical dimensions for direct substitution. Check if alternative suppliers offer matching electrical parameters including 15pF load capacitance and 30 Ohm ESR.
