Procurement Notes
Verify current product status as this component has been announced End-of-Life. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing PCB layouts and reflow soldering profiles. Check for RoHS compliance documentation if required for specific regulatory environments. Validate substitute components if original supply is unavailable.
Selection Notes
Select this component for applications requiring precise low-pass filtering in the 5GHz band. Consider the 0603 package size for space-constrained designs. Evaluate insertion loss and attenuation specifications against system noise floor requirements. Ensure impedance matching with surrounding circuitry to minimize signal reflection. Verify thermal stability for intended operating temperature ranges.
