Procurement Notes

Verify the specific suffix designation carefully, as availability varies between T2 and T3 variants. Confirm current manufacturing status, as some listings indicate this model may be obsolete or discontinued. Ensure compatibility with existing PCB footprints and reflow soldering profiles suitable for moisture-sensitive devices.

Selection Notes

Select this component when a narrow 20 MHz bandwidth is required specifically at the L5 GNSS frequency band. Compare insertion loss specifications against system link budget requirements. Evaluate the 4-SMD footprint dimensions against available board space constraints. Consider thermal performance limits relative to the intended operational environment.
