Procurement Notes

Verify the specific suffix designation, as bulk packaging variants may differ from reel configurations regarding factory pack quantities. Confirm RoHS compliance status through official documentation prior to procurement. Ensure the selected part number matches the required load capacitance and frequency tolerance for the target circuit design to avoid compatibility issues during implementation.

Selection Notes

Select this component when a 14.31818 MHz reference is required for SMD applications. Consider the 18 pF load capacitance requirement for oscillator circuit design. Evaluate the -10°C to +60°C temperature range against environmental constraints. Compare ESR and drive level specifications with the host oscillator's capabilities to ensure stable operation without overdriving the crystal element.

Part Context

This part belongs to the CFPX-104 series of quartz crystals manufactured by IQD Frequency Products. It serves as a passive timing element essential for establishing clock frequencies in electronic systems.
