TC9-1-75X+

Balun Overview

The TC9-1-75X+ is a core and wire transformer manufactured by Mini-Circuits, designed for RF applications. It operates within a frequency range of 0.3 MHz to 475 MHz. The component functions as a step-down autotransformer with a turns ratio of 1:0.11. It features a 75 Ohm secondary impedance and utilizes a plastic base construction. The device is aqueous washable and supports surface mount integration.

Balun Feature Summary

• Core and wire transformer design
• Step-down autotransformer configuration
• Aqueous washable plastic base

Balun Applications

• Laser diode matching
• RF signal transformation
• Balanced to unbalanced conversion

Balun Procurement Notes

Verify the specific suffix designation against official Mini-Circuits documentation to confirm exact electrical characteristics and physical dimensions. Ensure compatibility with aqueous cleaning processes if required by the assembly workflow. Cross-reference the 75 Ohm impedance requirement with system specifications to prevent mismatch issues during implementation.

Balun Selection Notes

Select this component when a 75 Ohm interface is required for frequencies extending up to 475 MHz. The 1:0.11 ratio suits applications needing significant step-down transformation. Consider the plastic base and washability for manufacturing environments requiring chemical resistance during board cleaning procedures.

Balun Part Context

This model belongs to the TC9 series of audio and signal transformers from Mini-Circuits. It is categorized under core and wire transformers, distinct from surface-mount or transmission line variants. The series provides passive components for RF and IF signal processing tasks.
