LFB212G45BA1B759

Overview

The Murata LFB212G45BA1B759 is a ceramic bandpass filter designed for EMI/RFI suppression. It features a center frequency of 2.45 GHz and a bandwidth of 50 MHz. The component operates within a temperature range of -40°C to +85°C and utilizes a 50 Ohm impedance. Packaged in an 0805 (2012 metric) surface-mount device (SMD) format, it offers an insertion loss of 3.5 dB. This part is classified as End-of-Life (EOL) and scheduled for obsolescence by the manufacturer.

Feature Summary

• Provides effective electromagnetic interference and radio frequency interference suppression through dedicated filtering capabilities.
• Utilizes a compact 0805 surface-mount package suitable for space-constrained circuit board layouts.

Applications

• Wireless LAN and Bluetooth signal processing
• General EMI/RFI suppression in RF circuits
• Signal conditioning for 2.45 GHz communication modules

Procurement Notes

This component is officially designated as End-of-Life (EOL) by Murata Electronics. Procurement should be approached with caution due to scheduled obsolescence. Verify current availability status directly with authorized distributors, as stock may be limited or discontinued. Ensure that any purchased units are genuine and match the specified datasheet parameters before integration into production systems.

Selection Notes

Select this component only if the specific 2.45 GHz center frequency and 50 MHz bandwidth align precisely with the design requirements. Due to its EOL status, alternative solutions should be evaluated for long-term supply chain stability. Confirm that the 0805 footprint and 50 Ohm impedance are compatible with the existing PCB layout and system architecture.
