ADT4-6T+

Balun Overview

The ADT4-6T+ is a surface-mount RF transformer manufactured by Mini-Circuits, designed for signal balancing and impedance transformation. It operates within a frequency range of 60 kHz to 300 MHz, providing a 1:4 turns ratio. The component features 50 Ohm primary and secondary impedances, making it suitable for standard RF circuit interfaces. It supports a maximum DC current of 30 mA and has a power rating of 250 mW. The device functions reliably between -20°C and +85°C. Packaged in a compact SMD format with dimensions of 3.81 mm x 3.81 mm x 4.06 mm, it ensures efficient integration into high-density electronic assemblies.

Balun Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Mini-Circuits or authorized distributors before procurement. Confirm that the operating temperature range and power ratings align with your system's thermal and electrical requirements. Ensure compatibility with surface-mount reflow soldering profiles specified in the manufacturer's documentation to maintain component integrity during assembly.

Balun Selection Notes

Select this component when a 1:4 impedance ratio is required for frequencies up to 300 MHz. It is appropriate for designs needing a small footprint with integrated balancing capabilities. Consider the 50 Ohm interface match for standard RF environments. Evaluate the thermal performance against the specified operating limits to ensure reliability under continuous load conditions in the target application.

Balun Part Context

The ADT4-6T+ belongs to Mini-Circuits' line of core and wire transformers, specifically engineered for RF and IF signal processing. It complements other baluns and transformers in the portfolio by offering a fixed 1:4 ratio in a robust surface-mount package. This series is widely used in telecommunications and consumer electronics where space efficiency and signal integrity are critical design constraints.

Balun Replacement Considerations

Consult official Mini-Circuits substitution guides for verified alternatives. Cross-reference parameters such as frequency range, impedance ratio, and physical dimensions to ensure functional equivalence. Generic substitutes may not meet the specific electrical tolerances or thermal characteristics defined in the original datasheet.
