Crystals Procurement Notes

Verify the specific suffix 'M' against official Suntsu documentation to confirm it denotes standard tape and reel packaging rather than bulk or tray formats. Ensure the requested quantity aligns with manufacturer minimum order requirements. Cross-reference the date code on incoming shipments to guarantee freshness and prevent moisture sensitivity issues during soldering processes.

Crystals Selection Notes

Select this component when a 40 MHz timing source is required with moderate stability specifications. The 18 pF load capacitance must match the circuit design requirements to ensure accurate frequency output. Consider the 40 Ohm ESR value for impedance matching purposes. This part is appropriate for space-constrained designs requiring reliable surface-mount integration without complex mounting hardware.

Crystals Part Context

This model belongs to the SXT32418 series of surface-mount crystals from Suntsu Electronics. The series offers various frequency options while maintaining consistent physical dimensions and electrical characteristics. The AA48 suffix typically indicates specific casing and electrode configurations common to this product line, ensuring compatibility with existing board layouts designed for similar components.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz SMD crystals with identical 18 pF load capacitance and comparable ESR values. Verify that alternative parts support the same -40°C to +85°C temperature range. Check mechanical footprint compatibility to ensure the replacement fits the existing 4-SMD no-lead pad layout without requiring PCB modifications.
