Procurement Notes

Verify the specific suffix '947' against official Murata documentation to confirm exact electrical tolerances and manufacturing lot details. Ensure compatibility with existing PCB footprints and thermal requirements before integration. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a fixed 2.45 GHz bandpass response is required for communication systems. Consider the 50 Ohm impedance match for standard RF interfaces. Evaluate the -40°C to +85°C operating range against environmental conditions. Confirm SMD package dimensions fit the design constraints.

Part Context

This component belongs to Murata's EMIFIL line of filters for communication equipment. It serves as a passive RF element used to isolate desired frequencies from noise or interference. The product falls under the broader category of signal conditioning devices essential for maintaining signal purity in wireless technologies.

Replacement Considerations

Consult official Murata substitution guides for verified equivalents. Generic replacements may not match the precise 2.45 GHz bandwidth or insertion loss characteristics. Verify that any substitute maintains the same 50 Ohm impedance and SMD footprint.
