Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct packaging configuration and compliance status. Confirm that the selected variant matches the required load capacitance and frequency tolerance specifications for the target circuit design. Cross-reference the part number with official distributor catalogs to validate availability and lead times prior to finalizing procurement orders.

Selection Notes

Select this component when a compact surface-mount solution is required for 12 MHz timing applications within commercial temperature limits. Ensure the circuit design accommodates the specified 18 pF load capacitance to maintain accurate frequency performance. Verify that the PCB footprint aligns with the 3.2mm x 5.0mm package dimensions and that the thermal environment remains within the -10°C to +60°C operational range.

Part Context

This component is part of the CFPX-104 series from IQD Frequency Products, which specializes in miniature quartz crystals for space-constrained electronics.
