Crystals Procurement Notes

Verify the specific suffix 'D' against datasheet documentation to confirm the exact electrical parameters, particularly the ESR value which may vary between series variants. Ensure the required load capacitance matches the circuit design, as this unit is specified for 18 pF. Confirm that the operating temperature range of -20°C to +70°C meets the environmental requirements of the target application before finalizing procurement.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency is required in a small form factor. Compare the 50 Ohm ESR against circuit drive level requirements to ensure stable oscillation. Consider the 4-SMD footprint compatibility with PCB layout constraints. Evaluate the ±30 ppm tolerance against system synchronization needs relative to higher precision alternatives.
