Procurement Notes

Verify the specific suffix 'MEIV' against official QST documentation to confirm exact frequency tolerance and temperature range specifications, as suffix variations often denote distinct performance grades. Ensure compatibility with existing PCB footprints for 4-SMD no-lead packages. Confirm that the application environment remains within the -40°C to +85°C operational limits to maintain the stated ±30 ppm stability. Check for any specific reflow soldering profile requirements associated with the MSL 1 classification during manufacturing processes.

Selection Notes

Select this component when a 25 MHz fundamental frequency with tight ±30 ppm stability is required for industrial-grade environments. It is appropriate for designs prioritizing moisture resistance due to its MSL 1 rating. Consider this part for space-constrained applications benefiting from the 4-SMD no-lead form factor. Evaluate if the specified operating temperature range aligns with the system's thermal profile before integration into final assemblies.
