LFB212G45BF5D072

Overview

The LFB212G45BF5D072 is a bandpass filter manufactured by Murata Electronics, designed for RF signal conditioning. It operates at a nominal center frequency of 2450 MHz with a bandwidth of 100 MHz. The component features an insertion loss of 3.3 dB and maintains a system impedance of 50 Ohms. It utilizes SMD/SMT termination styles and is housed in a compact 0805 (2012 Metric) package measuring 2 mm x 1.25 mm x 0.7 mm. The device supports surface mount board mounting and functions within a minimum operating temperature of -40 C.

Feature Summary

• Provides bandpass filtering characteristics for RF applications
• Optimized for operation at 2450 MHz center frequency
• Utilizes a compact 0805 surface mount package

Applications

• WLAN systems
• Bluetooth connectivity modules

Procurement Notes

Verify the specific datasheet version and RoHS compliance status before integration. Confirm that the 0805 footprint dimensions align with the target PCB layout. Ensure the 50 Ohm impedance matches the circuit design requirements. Check for any recent product discontinuation notices or lifecycle changes from the manufacturer to ensure long-term availability.

Selection Notes

Select this component when a narrow bandpass response centered at 2.45 GHz is required. The 3.3 dB insertion loss represents a moderate signal attenuation trade-off for the specified bandwidth. The 0805 package offers a balance between size constraints and thermal performance for surface mount assembly processes.

Part Context

This part belongs to Murata's LFB series of RF filters. These components are engineered for wireless communication devices requiring precise frequency selection. The series typically includes various center frequencies and bandwidth options to support different global wireless standards and protocols.

Replacement Considerations

LFL212G45TC1A007 is a low-pass alternative in the same package but differs in filter type.
