LFB215G51SG8A132

Overview

The LFB215G51SG8A132 is a surface-mount bandpass ceramic filter manufactured by Murata Electronics. It operates at a center frequency of 5.512 GHz with a bandwidth of 363 MHz and an insertion loss of 1.9 dB. The component utilizes an 0805 (2012 Metric) package, designed for signal conditioning in RF applications.

Feature Summary

• Provides effective EMI/RFI suppression through bandpass filtering characteristics
• Engineered for high-frequency signal conditioning in communication equipment
• Utilizes compact surface-mount technology for efficient PCB integration

Applications

• RF local circuits in communication equipment
• Signal conditioning modules requiring specific frequency selection
• EMI/RFI suppression in wireless transmission systems

Procurement Notes

Verify the current lifecycle status before procurement, as this part is scheduled for obsolescence and will be discontinued by the manufacturer. Confirm that the 0805 package dimensions align with existing board layouts. Ensure compatibility with the target 5.512 GHz operating environment. Review official datasheets for precise electrical tolerances and thermal handling requirements to prevent integration issues during final assembly.

Selection Notes

Select this component when a fixed center frequency of 5.512 GHz is required for RF signal processing. The narrow bandwidth of 363 MHz suits applications needing precise frequency isolation. Consider the 1.9 dB insertion loss impact on system gain. The 0805 footprint offers space efficiency for dense circuit designs. Evaluate alternative components if long-term supply availability is a critical constraint due to the end-of-life status.

Part Context

This component belongs to Murata’s line of filters for communication equipment, specifically designed for RF and local signal paths. It serves as a passive signal conditioning element within larger radio frequency subsystems. The product represents Murata’s expertise in miniaturized ceramic filter technologies for modern wireless infrastructure and portable devices.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the specific 5.512 GHz center frequency and 363 MHz bandwidth, generic replacements may not match performance. Designers should consult Murata for approved alternatives or consider redesigning around available active solutions.
