Procurement Notes

Verify current availability status as this component is scheduled for obsolescence and will be discontinued by the manufacturer. Confirm that the RoHS3 compliance and MSL 1 ratings meet specific project requirements before finalizing procurement plans. Ensure sourcing channels provide authentic products to avoid counterfeit risks associated with end-of-life components.

Selection Notes

Select this component when designing systems requiring precise attenuation above 2.5GHz while maintaining signal integrity below 2.4GHz. The 0805 package size suits high-density PCB layouts. Consider the 0.9dB insertion loss impact on overall system gain. Verify that the 100MHz bandwidth aligns with the specific spectral mask requirements of the target application.

Part Context

This part belongs to Murata's LFB series of band-pass and low-pass filters, widely used in wireless infrastructure and consumer electronics. The LFB212G45CG1C187 specifically targets ISM band applications. Its design emphasizes minimal signal distortion and high rejection ratios outside the passband, supporting robust RF performance in noisy environments.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the scheduled obsolescence, engineers should identify alternative components from Murata or other manufacturers with compatible 0805 footprints, 2.45GHz center frequencies, and similar electrical specifications.
