LFB212G45SG8A166

Overview

The Murata LFB212G45SG8A166 is a surface-mount ceramic bandpass filter designed for communication equipment. It features a center frequency of 2.45 GHz and a bandwidth of 50 MHz. The component operates within a temperature range of -40°C to +85°C. Key electrical specifications include a maximum insertion loss of 1.4 dB at the center frequency. The device is housed in an 0805 (2012 Metric) package with four pad contacts, suitable for automated assembly processes.

Feature Summary

• Utilizes ceramic technology for stable RF signal filtering
• Optimized for compact surface-mount integration
• Designed for high-reliability wireless applications

Applications

• Wireless LAN modules
• Bluetooth transceivers
• ISM band communication devices

Procurement Notes

Verify the specific suffix code against official Murata documentation to confirm exact electrical tolerances and tape-and-reel packaging specifications. Ensure compatibility with standard 0805 footprint designs during PCB layout. Confirm RoHS compliance status through current manufacturer declarations prior to final procurement approval.

Selection Notes

Select this component when a narrow 50 MHz bandwidth is required around the 2.45 GHz ISM band. The low insertion loss characteristic supports efficient power transmission in sensitive RF front-ends. The small form factor aids in minimizing board space consumption for portable wireless devices requiring robust signal isolation.

Part Context

This part belongs to Murata's LFB series of ceramic filters, which are engineered for cost-effective and reliable performance in consumer electronics. The series provides standardized solutions for common wireless frequencies, ensuring consistent quality across various communication standards and reducing design complexity for manufacturers.

Replacement Considerations

Cross-reference with other Murata LFB series variants sharing the same 0805 footprint and 2.45 GHz center frequency. Verify that substitute components maintain identical bandwidth and insertion loss requirements to ensure circuit performance integrity without redesigning the surrounding RF matching network.
