Crystals Procurement Notes

Verify the specific suffix 'V' against the official TXC datasheet to confirm package dimensions and termination finish. Ensure the design accounts for the 100 Ohm ESR limit during oscillator circuit tuning. Confirm that the -20°C to +70°C operating range meets the environmental requirements of the final application before integration.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental frequency is required with ±20 ppm stability. The 8 pF load capacitance must match the oscillator circuit's external capacitors. Consider the 100 Ohm ESR maximum for drive level sensitivity. This part is suitable for space-constrained designs requiring a 3.2x2.5 mm footprint.

Crystals Part Context

This crystal belongs to the 8Q series of ceramic and quartz components from TXC Corporation. The series focuses on small-form-factor surface-mount devices. The 8Q designation typically indicates specific dimensional constraints and mounting styles common in modern portable electronics and compact industrial modules.
