Crystals Procurement Notes

Verify the specific suffix 'AAJ' against the manufacturer's current datasheet to confirm the exact load capacitance and ESR specifications, as suffixes often denote critical electrical variations. Ensure the procurement channel provides valid traceability documentation for AEC-Q200 certified components intended for automotive use. Cross-reference the package dimensions with the PCB footprint library to prevent assembly errors due to potential minor design revisions.

Crystals Selection Notes

Select this component when a 27.12 MHz reference signal is required with ±30 ppm stability in a small form factor. The 18 pF load capacitance must match the oscillator circuit design to ensure accurate frequency generation. Consider the -20°C to +70°C operating range against environmental conditions; if wider temperature stability is needed, alternative series with lower ppm drift should be evaluated. Verify that the 100 Ohm ESR limit aligns with the host oscillator's drive level requirements.

Crystals Part Context

This part belongs to the 8Q series of crystals from TXC Corporation, which focuses on small-sized, low-power solutions for portable and automotive electronics. The series utilizes advanced manufacturing techniques to achieve high frequency stability in miniature packages. The 8Q line is specifically engineered to meet the rigorous demands of modern digital interfaces and wireless communication protocols requiring precise clock synchronization.

Crystals Replacement Considerations

Direct substitutes include other 27.12 MHz crystals with identical 18 pF load capacitance, 100 Ohm ESR, and 1.6x1.2 mm SMD packaging. Ensure any replacement maintains AEC-Q200 certification if used in automotive applications. Verify that the substitute's frequency stability meets or exceeds ±30 ppm across the specified temperature range.
