Procurement Notes

Verify the current lifecycle status before procurement, as this component is scheduled for obsolescence and discontinuation by the manufacturer. Confirm that the 0805 package dimensions and 50Ω impedance requirements align with the target circuit design. Ensure compatibility with existing supply chains given the end-of-life designation.

Selection Notes

Select this component when a 50Ω bandpass filter is required for RF signals near 1.9GHz or broader ranges up to 5.95GHz. The 0805 package suits space-constrained designs. Verify that the 2.2dB insertion loss meets system sensitivity requirements. Consider alternative components if long-term availability is critical due to the discontinued status.

Part Context

This part belongs to Murata's line of chip multilayer LC filters intended for communication equipment.
