Crystals Procurement Notes

Verify current availability status as the part may be discontinued or subject to supply limitations. Confirm that the required load capacitance matches the target circuit design specifications. Ensure the operating temperature range meets the environmental requirements of the final application. Check for alternative packages if space constraints differ from the standard 4-SMD form factor.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency is required with specific 12 pF load capacitance. Consider the ±15 ppm stability requirement against system timing accuracy needs. Evaluate the 100 Ohm ESR value for compatibility with the oscillator circuit's drive level constraints. Verify that the 4-SMD footprint fits within the available PCB area.
