Crystals Procurement Notes

Verify the specific frequency tolerance variant required, as documentation references both ±20 ppm and ±50 ppm specifications. Confirm package dimensions against PCB footprint requirements. Ensure the operating temperature range meets the environmental conditions of the final application. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability.

Crystals Selection Notes

Select this component when a 40 MHz reference signal is needed in a small form factor. Consider the load capacitance requirement of the host circuit to ensure accurate frequency tuning. Evaluate the thermal environment to confirm compatibility with the stated operating range. Compare alternative packages if space constraints differ from the 4-SMD configuration.
