Procurement Notes

Verify the specific datasheet revision and RoHS compliance status before integration, as manufacturing notifications may update material compositions. Confirm that the 5-SMD leadless package dimensions align precisely with the target PCB footprint. Ensure handling procedures account for moisture sensitivity levels during storage and reflow soldering processes to maintain component integrity.

Selection Notes

Select this component when a dedicated SAW filter is required for the 869 MHz ISM band within a minimal footprint. The 50 Ohm impedance matches standard RF transmission lines. Consider the wide operating temperature range for industrial environments. Verify that the 2.7dB insertion loss meets system link budget requirements compared to alternative filter technologies.
