LFB182G45BG2D280

Balun Overview

The Murata LFB182G45BG2D280 is a low-capacitance balanced filter designed for RF applications in the 2400MHz to 2500MHz frequency range. It features a 6-SMD surface-mount package with mechanical dimensions of 1.6 mm x 0.8 mm (EIA 0603). The device operates as an LC balanced filter with 50-ohm impedance and supports power capacities of 500mW or 1W. It exhibits a maximum insertion loss of 1.9dB and functions effectively within a temperature range starting at -40°C.

Balun Feature Summary

• Integrates balanced filtering functionality into a compact six-pin SMD footprint
• Optimized for low capacitance to preserve signal integrity in RF paths
• Supports high power handling capabilities suitable for active transmission stages

Balun Applications

• Bluetooth module integration
• Zigbee wireless communication systems
• IEEE 802.15.4 compliant devices
• TI CC253x and CC254x series transceivers

Balun Procurement Notes

Verify component authenticity through authorized Murata distributors or certified supply chain partners. Confirm that the received units match the specific LFB182G45BG2D280 designation, as suffix variations may indicate different electrical characteristics or packaging formats. Ensure storage conditions comply with moisture sensitivity levels to maintain solderability and performance reliability prior to assembly.

Balun Selection Notes

Select this component when space constraints require a 0603 form factor for RF balancing tasks. It serves as a direct replacement for discrete balun networks in 2.4GHz ISM band designs. Consider its insertion loss specifications relative to system noise floor requirements. Evaluate thermal management needs against its 500mW or 1W power rating depending on transmit power levels.

Balun Part Context

This part belongs to the LFB182G series of low-capacitance balanced filters manufactured by Murata Electronics. The series targets short-range wireless protocols operating in the 2.4GHz and 2.5GHz bands. These components replace multiple discrete passive elements, reducing board area and improving consistency in impedance matching for modern mobile and IoT hardware architectures.
