ATB2012E-75011M-T01

Balun Overview

The ATB2012E-75011M-T01 is a surface-mount RF balun manufactured by TDK Corporation, designed for commercial-grade applications. It operates within a frequency range of 400 MHz to 1.8 GHz and features balanced impedances of 75 Ohms on both sides. The component utilizes an 0805 (2012 Metric) package with precise dimensions of 2.00 mm in length and 1.20 mm in width, each with a tolerance of ±0.20 mm. This device serves as a passive component for signal conversion in wireless communication systems.

Balun Feature Summary

• Provides balanced-to-balanced impedance transformation between two 75 Ohm ports
• Operates effectively across the 400 MHz to 1.8 GHz frequency spectrum
• Utilizes a compact 0805 surface-mount footprint for space-constrained designs

Balun Applications

• DVB-H digital video broadcasting handheld receivers
• ISDB-T terrestrial digital television reception modules

Balun Procurement Notes

Verify that the ordering suffix matches the required impedance and frequency specifications exactly. Confirm the package type corresponds to the 0805 metric standard. Ensure the component grade aligns with commercial application requirements rather than industrial or automotive standards. Cross-reference the manufacturer part number with official TDK documentation to avoid substitution errors.

Balun Selection Notes

Select this component when a balanced 75 Ohm interface is required for frequencies up to 1.8 GHz. The choice depends on the need for a compact SMD solution compatible with DVB-H and ISDB-T standards. Consider the physical dimensions and impedance balance characteristics against circuit board layout constraints and signal integrity requirements for the specific target application.

Balun Part Context

This balun belongs to the ATB series from TDK Corporation, which focuses on passive components for radio frequency applications. The series includes various models tailored for different impedance configurations and frequency ranges. The ATB2012E variant specifically addresses the needs of digital broadcasting systems requiring reliable signal balancing in a small form factor.
