T4-6T+

Balun Overview

The T4-6T+ is a core and wire transformer manufactured by Mini-Circuits, designed for RF signal processing applications. It operates within a frequency range of 20 kHz to 250 MHz. The component features a 1:4 impedance transformation ratio with both primary and secondary coils rated at 50 Ohms. It supports a maximum DC current of 30 mA and has a power rating of 250 mW. The device utilizes SMD/SMT termination and is housed in a compact package measuring 7.62 mm x 6.86 mm. It functions as a single-channel balun suitable for surface-mount PCB assembly.

Balun Feature Summary

• Provides 1:4 impedance transformation between balanced and unbalanced lines
• Operates across a wide bandwidth from 20 kHz to 250 MHz
• Designed for surface-mount technology integration

Balun Applications

• RF signal balancing and impedance matching
• Audio and signal transformer circuits
• Mixed-signal circuit interfaces

Balun Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required mounting configurations. Confirm that the 50-Ohm system impedance aligns with the target circuit design. Check RoHS compliance status if environmental regulations apply. Ensure the operating temperature range of -20 C to +85 C meets the application's thermal requirements. Validate the 30 mA DC current limit against peak operational loads.

Balun Selection Notes

Select this component when a 1:4 transformation ratio is required for frequencies up to 250 MHz. Consider the physical dimensions of 7.62 mm x 6.86 mm for PCB layout constraints. Evaluate the 250 mW power rating to prevent saturation or overheating. Ensure the SMD package type matches the manufacturing process. Compare performance against other baluns if higher frequency operation beyond 250 MHz is needed.

Balun Part Context

The T4-6T+ belongs to the T4 series of audio and signal transformers produced by Mini-Circuits. This series focuses on providing reliable impedance conversion for RF and microwave applications. The component serves as a passive interface element in communication systems, bridging different impedance levels while maintaining signal integrity across the specified frequency band.

Balun Replacement Considerations

Consult official Mini-Circuits documentation for direct substitutes. Verify equivalent electrical parameters such as impedance ratio and frequency range before substitution.
