Procurement Notes

Verify the specific suffix P810 to confirm the tape and reel packaging configuration. Ensure compatibility with the target PCB footprint dimensions of 1.40mm by 1.10mm. Confirm that the 5MHz bandwidth aligns with the system's spectral requirements. Check for any recent Product Change Notifications regarding assembly or material updates.

Selection Notes

Select this component when a narrow 5MHz bandwidth is required at 922.5MHz. The low profile of 0.45mm suits space-constrained designs. Consider the AEC-Q200 rating if automotive environmental resilience is necessary. Compare insertion loss specifications against other SAW options to ensure signal integrity meets system thresholds.
