Crystals Procurement Notes

Verify the specific suffix 'W31' against official CTS documentation to confirm the exact frequency tolerance and temperature range specifications. Ensure the application circuit supports the 18 pF load capacitance and 100 uW excitation level. Confirm that the 0°C to +50°C operating range meets the environmental requirements of the final product. Cross-reference the 5x3.2mm footprint with the PCB layout guidelines provided in the manufacturer's datasheet.

Crystals Selection Notes

Select this component when a 13 MHz fundamental frequency with ±30 ppm stability is required for surface-mount applications. Consider the 18 pF load capacitance compatibility with the host oscillator circuit. Evaluate the 50 Ohm ESR against the oscillator driver strength. Verify that the 0°C to +50°C temperature range is sufficient for the intended operational environment compared to wider industrial ranges.
