TC1-1T-75X+

Balun Overview

The TC1-1T-75X+ is a surface-mount RF transformer manufactured by Mini-Circuits. It operates within a frequency range of 5 to 120 MHz and features a 75Ω impedance configuration. The device utilizes a core and wire construction method, providing DC isolation between ports. A secondary center tap is integrated into the design to facilitate specific circuit requirements. The component is housed in an AT1521 case style and is supplied in tape and reel packaging for automated assembly processes.

Balun Feature Summary

• Provides signal transformation with a 1:1 turns ratio
• Features a secondary center tap for balanced circuit integration
• Ensures electrical isolation between primary and secondary circuits

Balun Applications

• RF signal processing in broadcast systems
• Impedance matching in 75Ω transmission line interfaces
• Differential signal conversion in IF stages

Balun Procurement Notes

Verify the exact suffix designation against the manufacturer datasheet to confirm impedance and frequency specifications. Ensure that the AT1521 package dimensions align with the PCB footprint requirements. Confirm that the supply voltage and current ratings remain within safe operating limits for the intended application environment.

Balun Selection Notes

Select this component when a 75Ω impedance match is required for frequencies up to 120 MHz. The integrated center tap makes it suitable for applications requiring balanced signal paths or specific biasing configurations. Consider the surface-mount form factor for compact board designs where space constraints are critical.

Balun Part Context

This part belongs to the TC1 series of audio and signal transformers from Mini-Circuits. The series offers various impedance options including 50Ω and 100Ω variants. The TC1-1T-75X+ specifically addresses needs for 75Ω systems, distinguishing it from other models in the lineup that target different standard impedances or broader frequency ranges.

Balun Replacement Considerations

Consult official substitution lists for compatible parts. Verify that any alternative component matches the 75Ω impedance, 5-120 MHz frequency range, and AT1521 package dimensions to ensure mechanical and electrical compatibility.
