ATB3225-75011CT-001

Balun Overview

The TDK ATB3225-75011CT-001 is a surface-mount audio and signal transformer designed for balanced-to-unbalanced conversion. It features a 1:1 turns ratio and a nominal impedance of 75 ohms, operating effectively within a frequency range of 5 MHz to 200 MHz. The component provides an insertion loss of 10 dB and is housed in a compact 1210 (3225 metric) package with dimensions of 3.20mm length, 2.50mm width, and 2.30mm thickness. It supports an operating temperature range from -25°C to 85°C.

Balun Feature Summary

Balun Procurement Notes

Verify the exact ordering suffix against official TDK documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the requested part number matches the specific variant required for your production line, as suffixes may indicate differences in reel size or packaging format rather than electrical performance changes.

Balun Selection Notes

Select this component when a 75-ohm impedance match is required for frequencies between 5 MHz and 200 MHz. Ensure the PCB layout accommodates the 1210 package dimensions and that the system design can tolerate the specified 10 dB insertion loss. Verify thermal requirements align with the -25°C to 85°C operating range.

Balun Part Context

This model belongs to the TDK ATB series of audio transformers. These components are engineered for high reliability in consumer electronics and industrial data processing equipment. The series offers various impedance options and form factors to support diverse signal integrity requirements in modern electronic assemblies.

Balun Replacement Considerations

Consult TDK's official cross-reference guides for verified substitutes. Ensure any replacement maintains the 1:1 ratio, 75-ohm impedance, and compatible frequency response. Verify mechanical compatibility with the 1210 footprint before integration.
