Procurement Notes

Verify the specific suffix Z810 against official Qualcomm documentation to confirm exact electrical characteristics and packaging details. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Confirm current availability status as product lifecycles may change. Cross-reference with authorized distributors for genuine sourcing to avoid counterfeit components.

Selection Notes

Select this component for designs requiring precise 315MHz filtering with low insertion loss. Consider the 8-SMD package size for space-constrained layouts. Verify that the AEC-Q200 rating meets specific automotive or industrial reliability requirements. Compare performance metrics against alternative SAW filters if wider bandwidth or different frequency ranges are needed.

Part Context
