TC1-1X+

Balun Overview

The TC1-1X+ is a surface-mount RF balun transformer manufactured by Mini-Circuits. It operates within a frequency range of 1.5MHz to 500MHz and provides a 50/50 Ohm impedance transformation. The component features a 5-SMD module package and complies with RoHS3 standards. Key electrical specifications include a maximum insertion loss of 3dB, a minimum return loss of 10.1dB, and a phase difference of 2 degrees. This device is designed for high-performance signal conversion in compact electronic assemblies.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion across a wide frequency spectrum
• Features a surface-mount 5-SMD module package for automated assembly compatibility
• Includes Top Hat marking for visual identification and improved pick-and-place efficiency

Balun Applications

• RF signal path balancing in communication systems
• Impedance matching between 50-ohm unbalanced and balanced circuits
• Integration into compact RF modules requiring surface-mount components

Balun Procurement Notes

Verify the specific ordering suffix to ensure the inclusion of the Top Hat feature, which aids in visual identification and assembly. Confirm that the required quantity aligns with the manufacturer's standard packaging options. Ensure the application environment is compatible with the specified operating temperature range and moisture sensitivity level. Cross-reference the datasheet for any recent updates to electrical performance criteria before finalizing procurement.

Balun Selection Notes

Select this component when a 50/50 Ohm impedance transformation is required within the 1.5MHz to 500MHz band. Consider the 5-SMD package size for board space constraints. Evaluate the insertion loss and return loss specifications against system requirements. Ensure the design supports surface-mount technology processes. Verify compatibility with adjacent components regarding thermal and electromagnetic interference.

Balun Part Context

The TC1-1X+ belongs to the TC1 series of audio and signal transformers from Mini-Circuits. This series spans frequencies from 0.15MHz to 4000MHz with various impedance options. The TC1-1X+ specifically targets the lower end of the RF spectrum with a 50/50 Ohm configuration. It represents an upgraded version of earlier models, incorporating design improvements for modern manufacturing processes.

Balun Replacement Considerations

The TC1-1TX+ is a confirmed substitute part number within the same product family. Both components share similar functional characteristics but may differ in physical marking or packaging details. Verify pinout compatibility and electrical parameters before substitution. Consult the official datasheets for both parts to confirm interchangeability in the specific application.
