TT1-6+

Overview

The TT1-6+ is a core and wire RF transformer manufactured by Mini-Circuits, designed for balanced-to-unbalanced signal conversion. It operates within a frequency range of 0.004 MHz to 300 MHz with a 1:1 impedance ratio. The component utilizes a 6-SMD, flat lead surface-mount package, measuring approximately 2.53 mm in length, 4.71 mm in width, and 0.29 mm in height. It features a center-tapped primary winding and a center-tapped secondary winding, supporting a maximum power rating of 250 mW and a current rating of 30 mA. The device functions reliably across an operating temperature range from -20°C to +85°C.

Feature Summary

• Provides balanced-to-unbalanced transformation using a core and wire construction method
• Features center-tapped windings on both primary and secondary sides for flexible circuit integration
• Supports high-frequency operation extending up to 300 MHz with a 1:1 impedance ratio

Applications

• RF signal path balancing and unbalancing in communication systems
• Impedance matching networks requiring center-tapped configurations
• Test and measurement equipment signal conditioning

Procurement Notes

Verify the specific suffix designation against official Mini-Circuits documentation to ensure correct pinout and electrical characteristics. Confirm that the 6-SMD flat lead package aligns with the target PCB footprint and soldering profile requirements. Check for any recent updates to the datasheet regarding thermal or electrical limits before finalizing the bill of materials.

Selection Notes

Select this component when a wideband 1:1 balun with center taps is required for frequencies up to 300 MHz. Ensure the application can accommodate the small SMD form factor and the specified power handling limits. Consider the operating temperature range if the environment exceeds standard commercial conditions.

Part Context

This part belongs to the T1 series of audio and signal transformers from Mini-Circuits. It is distinct from similar models like the T1-6-KK81+ which may have different frequency ranges or packaging options. The TT1-6+ specifically addresses applications needing a compact, wideband solution with center-tapped symmetry.
