ATB2012-50011M

Balun Overview

The ATB2012-50011M is a surface-mount balun transformer manufactured by TDK Corporation, designed for RF applications. It operates within a frequency range of 40MHz to 860MHz and provides balanced-to-unbalanced signal conversion with an impedance ratio of 50/50 Ohms. The component features a maximum insertion loss of 1.02dB and is housed in a compact 0805 (2012 Metric) SMD package. It supports a minimum operating temperature of -40°C and a maximum operating temperature of 85°C, ensuring reliability across diverse environmental conditions.

Balun Feature Summary

• Provides balanced-to-unbalanced signal transformation for RF circuits
• Operates effectively across a wide frequency spectrum from 40MHz to 860MHz
• Utilizes a compact 0805 surface-mount package for space-constrained designs

Balun Applications

• RF front-end modules in wireless communication devices
• Antenna matching networks requiring impedance transformation
• Balanced line drivers in broadband signal processing

Balun Procurement Notes

Verify the specific suffix 'M' against official TDK documentation to confirm exact specifications, as ordering suffixes may denote variations in packaging or tape-and-reel configurations. Ensure compatibility with standard 0805 footprints during PCB layout. Cross-reference datasheets for thermal performance limits to validate suitability for the intended operational environment.

Balun Selection Notes

Select this component when a 50-ohm balanced-to-unbalanced transformation is required within the 40MHz to 860MHz range. Consider the low insertion loss specification for high-efficiency signal integrity. Evaluate the 0805 package size against available board real estate. Confirm that the operating temperature range meets the system's environmental requirements.
