Procurement Notes

Verify the specific impedance requirement (50 Ohm vs 120 Ohm) against your schematic, as datasheets indicate multiple variants within this series. Confirm the package dimensions match your PCB footprint constraints. Ensure the operating temperature range aligns with your system's thermal environment. Cross-reference the manufacturer part number to avoid confusion with similar SG7 series components.

Selection Notes

Select this component when a compact ceramic filter is required for 2.45 GHz applications. Consider the 1008 package size for space-constrained designs. Evaluate the 3.2 dB insertion loss against system link budget requirements. Verify compatibility with standard SMT reflow processes. Check if the specific impedance variant matches the surrounding circuit topology.
