TC1-1+

Balun Overview

The TC1-1+ is a surface-mount RF balun transformer manufactured by Mini-Circuits. It operates within a frequency range of 1.5MHz to 500MHz and provides impedance transformation between unbalanced and balanced ports, both rated at 50 ohms. The component utilizes a 5-SMD module package for board integration. Key electrical specifications include a maximum insertion loss of 3dB, a minimum return loss of 10.1dB, and a phase difference of 2 degrees. It complies with RoHS3 standards.

Balun Feature Summary

• Provides conversion between single-ended and differential signals
• Supports surface mount assembly for compact designs
• Maintains consistent 50-ohm impedance across ports

Balun Applications

• RF signal path balancing in communication systems
• Differential driver interfacing in wireless modules
• Impedance matching in broadband antenna circuits

Balun Procurement Notes

Verify the specific suffix designation against official Mini-Circuits documentation to ensure compatibility with required performance parameters. Confirm that the selected variant matches the intended frequency range and impedance requirements for the target application design.

Balun Selection Notes

Select this component when a wideband solution covering low-frequency audio up to VHF ranges is required. Ensure the PCB layout accommodates the 5-SMD footprint and allows for proper grounding to maintain specified return loss and isolation characteristics.

Balun Part Context

This part belongs to the TC1 series of core and wire transformers from Mini-Circuits. The series offers various impedance configurations and frequency ranges, utilizing standard winding techniques to provide reliable balance-to-unbalance conversion for RF and IF applications.

Balun Replacement Considerations

Consult Mini-Circuits official substitution lists for direct equivalents. Verify that alternative components match the 5-SMD package dimensions and pinout configuration to ensure mechanical fit without requiring PCB redesign.
