TC1-1TG2+

Balun Overview

The TC1-1TG2+ is a surface-mount RF transformer manufactured by Mini-Circuits, designed for balanced-to-unbalanced signal conversion. It operates within a frequency range of 0.4 MHz to 500 MHz with a 1:1 impedance ratio between 50 Ohm primary and secondary windings. The component features a compact 6-SMD package with dimensions of 3.81 mm x 3.81 mm x 3.81 mm. It supports a maximum DC current of 30 mA and functions reliably across an operating temperature range from -40°C to +85°C.

Balun Feature Summary

• Provides balanced-to-unbalanced transformation for RF signals
• Minimizes phase difference between output channels
• Ensures low insertion loss for efficient signal transfer

Balun Applications

• Wideband push-pull amplifier circuits
• HF/VHF receiver and transmitter systems
• Balanced antenna impedance matching applications

Balun Procurement Notes

Verify the RoHS compliance status and specific ordering suffixes when sourcing this component. Confirm that the supplier provides official datasheets matching the TC1-1TG2+ designation. Ensure the received parts match the specified 6-SMD footprint and electrical characteristics before integration into production lines.

Balun Selection Notes

Select this transformer for designs requiring wideband operation up to 500 MHz in a small surface-mount form factor. It is suitable for applications needing precise 1:1 impedance transformation between balanced and unbalanced lines. Consider the thermal limits and DC current rating when designing power stages or high-signal environments.

Balun Part Context

This component belongs to the TC1 series of audio and signal transformers from Mini-Circuits. The series includes various variants optimized for different frequency ranges and packaging styles. The TC1-1TG2+ specifically addresses needs for compact, high-performance RF balancing in modern electronic systems.

Balun Replacement Considerations

Direct substitutes include other Mini-Circuits models such as TC1-1T+ or TC1-1TX+. Verify pin compatibility and frequency response overlap before swapping components in existing PCB layouts.
