Crystals Procurement Notes

Verify the specific suffix 'D' against the manufacturer's official datasheet to confirm the exact frequency tolerance and temperature range specifications. Ensure that the 4-SMD footprint matches the PCB land pattern dimensions precisely. Confirm that the load capacitance requirements of the host circuit align with the component's 20pF rating to maintain accurate frequency performance. Check for any recent product change notices regarding material or manufacturing location updates.

Crystals Selection Notes

Select this component when a 14.31818 MHz fundamental frequency is required for digital logic synchronization. The 4-SMD package offers space efficiency compared to through-hole alternatives. Consider the ±30 ppm tolerance if higher precision is not critical. Evaluate the -20°C to +70°C operating range against the environmental conditions of the final assembly. Compare ESR values with oscillator input impedance requirements to ensure reliable startup.
