LFL182G45TC3B746

Overview

The Murata LFL182G45TC3B746 is a surface-mount low-pass RF filter designed for the 2.45 GHz ISM band. It features a center frequency of 2.45 GHz and a bandwidth of 50 MHz, with a nominal insertion loss of 0.6 dB. The component operates at a system impedance of 50 Ohms and is housed in a compact 0603 (1608 Metric) package. It supports SMD/SMT termination styles and is suitable for applications requiring precise signal filtering in wireless communication systems.

Feature Summary

• Provides effective attenuation of out-of-band signals while maintaining signal integrity within the passband.
• Utilizes a compact 0603 footprint to optimize PCB space utilization in dense layouts.
• Engineered for stable performance across standard operating temperature ranges.

Applications

• Bluetooth module input/output stages
• Wi-Fi transceiver front-end filtering
• ISM band wireless sensor networks

Procurement Notes

Verify the specific suffix 'TC3B746' against official Murata documentation to confirm tape-and-reel packaging quantities and lead times. Ensure compatibility with existing BOM specifications regarding RoHS compliance and end-of-life status before finalizing procurement orders.

Selection Notes

Select this component when a low-pass characteristic is required specifically for the 2.45 GHz band with minimal insertion loss. Compare electrical parameters such as stopband rejection and power handling against alternative filters if higher isolation or different form factors are needed for the target application design.

Part Context

This part belongs to Murata's LFL series of ceramic RF filters. These components are widely used in consumer electronics and industrial equipment for noise suppression and harmonic reduction in short-range wireless devices, offering a balance between performance and size constraints typical of modern portable hardware.

Replacement Considerations

Check Murata datasheets for direct pin-compatible alternatives within the LFL series. Verify that any substitute maintains identical 0603 dimensions, 50 Ohm impedance, and 2.45 GHz center frequency specifications to ensure circuit functionality remains unchanged.
