Crystals Procurement Notes

Verify the specific suffix code (e.g., FD07) against the required temperature range and frequency tolerance before ordering. Confirm that the 4-SMD footprint matches the target PCB layout. Ensure the load capacitance requirement aligns with the host circuit design to maintain accurate frequency performance.

Crystals Selection Notes

Select this component when a 12.288 MHz reference is required for serial communication standards such as RS-232 or Ethernet. Compare stability requirements to choose between ±10 ppm and ±20 ppm variants. Ensure the operating environment temperature falls within the specified range for the selected suffix to guarantee long-term reliability.
