Crystals Procurement Notes

Verify the specific suffix 'AAQ' against the official datasheet to confirm the exact frequency tolerance and temperature range specifications. Ensure the ordering quantity aligns with the manufacturer's standard reel packaging requirements. Cross-reference the package dimensions with the target PCB footprint to guarantee mechanical compatibility during assembly.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency is required with ±30 ppm stability. The 10 pF load capacitance must match the oscillator circuit design. Consider the 60 Ω ESR value for drive level sensitivity. The -40°C to +85°C range suits industrial applications requiring robust thermal performance compared to commercial grade alternatives.

Crystals Part Context

This part belongs to the 7V series of ceramic crystals manufactured by TXC Corporation. The series offers various frequencies and packages optimized for surface mount technology. The 7V designation indicates a specific form factor within the broader portfolio of passive timing components designed for consumer and industrial electronics.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz SMD crystals with identical 10 pF load capacitance and similar ESR values. Verify that alternative parts support the same 4-SMD 3.2x2.5mm footprint and meet the -40°C to +85°C temperature requirement to maintain system reliability.
