Procurement Notes

Verify the exact datasheet version as multiple sources cite varying insertion losses (3dB vs 3.8dB). Confirm package compatibility during integration. Note that availability may be limited due to potential end-of-life status or discontinuation notices found in distributor records. Ensure compliance with current environmental regulations such as RoHS3.

Selection Notes

Select this component when a SAW filter is required for 942.5MHz applications. Consider the 35MHz bandwidth relative to system requirements. Evaluate the 6-SMD footprint against PCB layout constraints. Compare insertion loss specifications across different supplier datasheets to ensure alignment with link budget calculations.
