Procurement Notes

Verify the specific orderable part number through authorized distributors such as DigiKey to ensure correct packaging options like tape and reel or cut tape. Confirm that the required frequency tolerance and load capacitance match your circuit design requirements before finalizing procurement. Check current availability due to potential supply chain fluctuations affecting lead times.

Selection Notes

Select this component when a compact, low-voltage ceramic oscillator is required for 25 MHz applications. Ensure the PCB layout accommodates the 4-SMD no-lead footprint dimensions. Verify that the system power supply remains within the 1.8V to 3.6V operational range. Consider the ±30 ppm stability requirement against your system's timing accuracy needs.
