Procurement Notes

Verify current availability status as distribution channels may indicate discontinuation or limited stock. Confirm that the specific ordering suffix matches the required packaging format, such as bulk or reel configurations. Ensure the selected variant aligns with the intended thermal and mechanical constraints of the target assembly process before finalizing procurement orders.

Selection Notes

Select this component when a 16 MHz fundamental frequency with 16 pF load capacitance is required for standard microcontroller or communication interfaces. The ±50 ppm stability across the -10°C to +60°C range suits industrial control and short-range communication scenarios without requiring external temperature compensation. Verify MCU drive strength compatibility with the 40 Ohm ESR limit to ensure reliable startup.
