Procurement Notes

Verify the specific suffix or variant against official Murata documentation to ensure compatibility with design requirements. Confirm that the AEC-Q200 qualification aligns with target application standards. Check for any recent lifecycle status updates, as availability may vary by region. Ensure the 10-SMD package dimensions fit the intended PCB layout constraints prior to finalizing procurement decisions.

Selection Notes

Select this component when a 611 MHz center frequency and 10 MHz bandwidth are required for SAW filtering. Consider the 10-SMD footprint for space-constrained designs. Verify thermal performance within the specified operating range. Ensure the low insertion loss meets system sensitivity requirements. Compare against alternative frequencies if the application spectrum differs from the 611 MHz specification.
