LFB212G45SG8A143

Overview

The Murata LFB212G45SG8A143 is a ceramic bandpass filter designed for EMI/RFI suppression. It operates at a center frequency of 2.45 GHz with a bandwidth of ±50 MHz. The device features a maximum insertion loss of 2.6 dB at 25°C within the specified bandwidth and 2.8 dB maximum at elevated temperatures. It utilizes an SMD/SMT termination style in an 0805 (2012 metric) package, supporting operation between -40°C and +85°C.

Feature Summary

• Provides effective electromagnetic interference and radio frequency interference suppression through ceramic bandpass filtering technology.
• Engineered for compact surface-mount integration using standard 0805 footprint dimensions.

Applications

• WLAN systems
• Bluetooth modules
