Procurement Notes

Verify the specific suffix and packaging configuration against the manufacturer's latest documentation before ordering. Confirm that the required frequency tolerance and temperature range align with the design specifications. Ensure compatibility with the target PCB footprint dimensions. Check for any recent part number revisions or obsolescence notices from IQD Frequency Products to avoid sourcing delays.

Selection Notes

Select this component when a precise 32.768 kHz reference is required for low-power applications. Consider the 30 ppm stability requirement against the environmental temperature variations expected in the final product. Evaluate the 3.3 V supply constraint relative to the system power rails. The small 2x1.6 mm package size should be weighed against available board space and assembly capabilities.

Part Context
