Crystals Procurement Notes

Verify the specific load capacitance requirements against the target circuit design to ensure accurate oscillation. Confirm that the operating environment remains within the specified -40°C to +85°C range. Check datasheet specifications for ESR limits to guarantee stable startup conditions. Ensure PCB footprint matches the 4-SMD no-lead package dimensions provided in the official documentation.

Crystals Selection Notes

Select this component when a standard 20 MHz reference is required for commercial-grade devices. Consider the 18 pF load capacitance requirement during schematic design. Evaluate the 60 Ohm ESR limit against oscillator circuit capabilities. Compare physical size constraints against alternative packages if space is limited.
