TC9-1X+

Balun Overview

The TC9-1X+ is a surface-mount RF balun transformer manufactured by Mini-Circuits. It operates within a frequency range of 2MHz to 200MHz and provides an impedance transformation ratio of 1:9. 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 6.08dB, and a phase difference of 1°. It is compliant with RoHS3 standards and features a moisture sensitivity level of 1.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion via core and wire construction
• Supports wide bandwidth operation from 2MHz to 200MHz
• Designed for surface mount assembly in compact modules

Balun Applications

• RF circuit impedance matching
• Signal balancing networks
• Telecommunications equipment

Balun Procurement Notes

Verify the specific suffix designation against official Mini-Circuits documentation to confirm exact performance characteristics. Ensure that ordering requirements align with manufacturer standard packaging quantities. Confirm compliance with relevant environmental regulations prior to final procurement decisions.

Balun Selection Notes

Select this component when a 1:9 impedance transformation ratio is required for frequencies up to 200MHz. Consider the 5-SMD footprint constraints during PCB layout. Evaluate insertion loss and return loss parameters against system signal integrity requirements.

Balun Part Context

This device belongs to the TC9 series of audio and signal transformers produced by Mini-Circuits. The series includes various configurations for different impedance ratios and frequency ranges. The TC9-1X+ specifically addresses applications requiring a 1:9 step-up or step-down ratio in a surface-mount format.

Balun Replacement Considerations

Consult official Mini-Circuits substitution guides for verified alternatives. Generic equivalents may not match the specified 1:9 ratio or 200MHz bandwidth limits.
