LFB212G45CG1B982

Overview

The Murata LFB212G45CG1B982 is a surface-mount bandpass filter designed for RF signal conditioning. It operates at a center frequency of 2450 MHz with a bandwidth of 100 MHz. The device features a maximum insertion loss of 1.0 dB at 25°C and supports a power handling capacity of 500 mW. Constructed in an 0805 (2012 metric) package, it functions within an operating temperature range of -40°C to +85°C. This component provides impedance matching for 50-ohm systems and utilizes SMD/SMT termination types for board mounting.

Feature Summary

• Provides selective frequency filtering for RF applications
• Supports high-power signal transmission up to 500 mW
• Ensures reliable operation across extended industrial temperature ranges

Applications

• Wireless LAN modules
• Bluetooth communication devices
• RFID reader circuits

Procurement Notes

Verify the current lifecycle status before procurement as this component is designated End of Life by the manufacturer. Confirm that the 0805 package dimensions align with existing PCB footprints. Ensure the 50-ohm impedance specification matches system requirements. Validate that the 1.0 dB insertion loss meets signal integrity standards for the specific application path.

Selection Notes

Select this component when a compact bandpass solution is required for 2.45 GHz ISM band operations. The 0805 form factor suits space-constrained designs. Consider the 100 MHz bandwidth for narrowband filtering needs. Evaluate thermal performance capabilities if the device operates near the upper temperature limit of 85°C.

Part Context

This part belongs to Murata's LFB series of LC filters. These components are engineered for consumer-grade electronic applications requiring efficient EMI/RFI suppression. The series typically integrates passive LC elements into small surface-mount packages to maintain signal purity in wireless transceivers.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the End of Life status, alternative sourcing may require consulting distributor-specific cross-reference lists or evaluating newer generation Murata products with compatible electrical specifications.
