Procurement Notes

Verify the specific packaging configuration required for production, as the component is available in tape and reel or cut tape formats. Confirm that the selected variant matches the exact dimensional and electrical specifications documented in the official datasheet. Ensure compliance with RoHS3 standards and check for any recent part number revisions or obsolescence notices issued by the manufacturer before finalizing procurement orders.

Selection Notes

Select this component when a 16 MHz reference signal is required within a compact surface-mount footprint. The 16 pF load capacitance must align with the oscillator circuit's input capacitance requirements to ensure accurate frequency performance. Consider the ±30 ppm initial tolerance and ±50 ppm total stability limits against the system's timing accuracy constraints. Verify that the 40 Ohm ESR value is compatible with the driving circuit's gain capabilities.
