ATB2012E-75011M-T000

Balun Overview

The ATB2012E-75011M-T000 is a miniature surface mount balun transformer manufactured by TDK Corporation. It operates within a frequency range of 400 MHz to 1.8 GHz and provides an unbalanced-to-balanced impedance conversion of 75 Ohms to 75 Ohms. The component utilizes a standard 0805 (2012 Metric) package, measuring 2.0 mm in length and 1.2 mm in width. Key electrical specifications include a maximum insertion loss of 2.0 dB and a return loss characteristic suitable for RF signal integrity.

Balun Feature Summary

• Converts unbalanced signals to balanced signals across the 400 MHz to 1.8 GHz spectrum
• Maintains 75 Ohm impedance matching on both differential and single-ended ports
• Designed for compact surface-mount integration using the 0805 footprint

Balun Applications

• RF front-end circuits requiring impedance transformation
• Wireless communication modules operating in VHF/UHF bands
• Balanced antenna interface connections

Balun Procurement Notes

Verify the complete part number including the suffix -T000 to ensure correct tape-and-reel packaging configuration. Confirm RoHS compliance status if required by specific manufacturing standards. Cross-reference the manufacturer's latest datasheet for any updates to mechanical dimensions or material composition prior to final procurement approval.

Balun Selection Notes

Select this component when a 75 Ohm to 75 Ohm balun is required for frequencies up to 1.8 GHz. The 0805 package size is appropriate for space-constrained designs where larger transformers cannot fit. Ensure the application environment supports the specified insertion loss limits and that the PCB layout accommodates the specific pinout configuration defined in the official documentation.

Balun Part Context

This device belongs to the ATB series of miniature balun transformers from TDK. The series offers various impedance configurations and frequency ranges tailored for different RF applications. The ATB2012E variant specifically targets the 75/75 Ohm requirement, distinguishing it from other series members that may offer 50 Ohm conversions or different bandwidth capabilities.

Balun Replacement Considerations

Consult the official TDK ATB series datasheet for direct cross-references. Verify that any substitute component matches the 400 MHz to 1.8 GHz frequency range and maintains the 75/75 Ohm impedance ratio. Ensure the replacement fits the 0805 footprint and meets the same insertion loss specifications.
