LDB211G8105C-001

Balun Overview

The LDB211G8105C-001 is a multilayer hybrid balun from Murata Electronics, designed for RF signal conditioning. It operates at a frequency of 1.81 GHz with a balanced/unbalanced impedance of 50/50 Ohms. The component features a maximum insertion loss of 1.1 dB and utilizes an 0805 (2012 metric) surface-mount package. It supports soldering via SMD/SMT termination types and functions within a temperature range of -40°C to +85°C. This device complies with RoHS3 directives and carries an MSL rating of 1.

Balun Feature Summary

• Multilayer hybrid construction for compact integration
• Balanced-to-unbalanced signal conversion capability
• Surface-mount design compatible with automated assembly

Balun Applications

• RF front-end modules in wireless communication devices
• Signal conditioning in balanced antenna interfaces
• Impedance matching in high-frequency circuit boards

Balun Procurement Notes

Verify current availability status as the component is listed as obsolete or end-of-life by major distributors. Confirm if alternative stock sources exist or if a direct replacement from the same manufacturer family is required. Check specific lot dates and storage conditions if procuring from secondary markets. Ensure compliance with RoHS3 standards matches project requirements.

Balun Selection Notes

Select this component only if the application requires a 50/50 Ohm balun at 1.81 GHz in an 0805 footprint. Consider the 1.1 dB insertion loss limit against system budget constraints. Evaluate thermal performance within the specified -40°C to +85°C operating range. Verify that the surface-mount package aligns with existing PCB layout capabilities.
