Crystals Procurement Notes

Verify the specific suffix FA17 against official Suntsu documentation to confirm exact electrical characteristics and mechanical dimensions. Ensure compatibility with reflow soldering profiles specified in the manufacturer datasheet. Cross-reference part numbers carefully as minor suffix variations may indicate different tolerances or packaging options.

Crystals Selection Notes

Select this component when a 40 MHz reference with ±10 ppm stability is required for space-constrained designs. The 18 pF load capacitance must match the circuit design requirements. Consider the 40 Ohm ESR for drive level limitations. Verify that the 4-SMD form factor fits the available PCB footprint constraints.

Crystals Part Context

This model belongs to the SXT324 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and tolerances in a compact 3.2mm x 2.5mm footprint. It is designed for applications requiring reliable frequency control in consumer electronics and industrial equipment.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz crystals with identical 18 pF load capacitance and similar ESR values. Check mechanical compatibility with the 4-SMD no-lead package. Verify thermal performance matches the original specification if operating in extreme environments.
