Procurement Notes

Verify the specific revision suffix when ordering, as indicated by documentation references such as SF2467H(R). Confirm that the required packaging format matches available options like cut tape or reel. Ensure compatibility with standard reflow soldering profiles, typically peaking at 260°C for limited durations. Cross-reference the manufacturer part number with official RFMi datasheets to confirm exact electrical tolerances and mechanical dimensions before finalizing procurement.

Selection Notes

Select this component for designs requiring compact SAW filtering in GNSS front-ends. The SM2016-4 package offers a small footprint suitable for space-constrained mobile devices. Verify that the 3V voltage rating aligns with the system's power supply constraints. Consider the AEC-Q200 qualification if the application demands automotive-grade reliability. Ensure the 34 MHz bandwidth adequately covers the intended navigation signal spectrum without excessive signal degradation.
