LFB182G45SG9A293

Overview

The LFB182G45SG9A293 is a ceramic bandpass filter from the Murata LFB182G series, designed for RF signal conditioning. It operates at a center frequency of 2.45 GHz with a bandwidth of 50 MHz and maintains a 50 Ohm impedance. The component utilizes SMD/SMT termination and is housed in a compact 0603 (1608 metric) package. It supports an operating temperature range from -40°C to +85°C and offers power handling capacities of 500 mW or 1 W.

Feature Summary

• Compact surface-mount design suitable for space-constrained PCB layouts
• High selectivity filtering characteristics centered at 2.45 GHz
• Robust thermal performance across industrial temperature ranges

Applications

• Wireless LAN modules requiring 2.4 GHz band filtering
• Bluetooth device front-end signal conditioning
• ISM band communication systems

Procurement Notes

Verify the specific suffix code against official Murata documentation to confirm exact electrical tolerances and packaging options. Ensure compatibility with standard reflow soldering profiles for 0603 ceramic components. Cross-reference part numbers with authorized distributors to avoid counterfeit sources. Confirm RoHS compliance status through current manufacturer declarations.

Selection Notes

Select this component when a narrow 50 MHz bandwidth is required at 2.45 GHz within a minimal footprint. The 50 Ohm impedance matches standard RF transmission lines. Consider the 0603 package size for high-density assembly needs. Evaluate thermal requirements against the specified -40°C to +85°C operational range.

Part Context

This part belongs to the LFB182G series of ceramic filters manufactured by Murata Electronics. These components are engineered for reliable performance in wireless communication applications. The series provides standardized solutions for filtering in the 2.4 GHz ISM band, ensuring consistent impedance matching and insertion loss characteristics across production batches.

Replacement Considerations

Consult official Murata substitution guides for compatible alternatives. Verify that any substitute maintains identical 2.45 GHz center frequency, 50 MHz bandwidth, and 0603 package dimensions. Ensure impedance and power handling specifications match the original design requirements.
