Crystals Procurement Notes

Verify the specific load capacitance requirement against the target circuit design, as this component utilizes an 18 pF value which differs from standard 20 pF configurations. Confirm that the application environment remains within the specified -40°C to +105°C operational limits to ensure long-term frequency stability. Ensure compatibility with the 4-SMD footprint dimensions during PCB layout verification.

Crystals Selection Notes

Select this component when an extended temperature range is required for industrial applications, distinguishing it from commercial-grade alternatives limited to -20°C to +70°C. Consider the 80 Ohm ESR specification to ensure proper oscillator circuit loading and startup conditions. Evaluate the ±30 ppm tolerance against system jitter requirements to determine if tighter specifications are necessary for high-precision timing applications.
