TC1-42+

Balun Overview

The TC1-42+ is an RF transformer from the Mini-Circuits TC1 series, designed for surface-mount applications. It operates within a frequency range of 250 kHz to 400 MHz and provides balanced-to-unbalanced signal conversion with a 50/50 Ohm impedance configuration. The component features a typical insertion loss of 0.3 dB at mid-band. It is housed in a compact 5-SMD module package, suitable for integration into various RF circuits requiring precise impedance matching and signal balancing.

Balun Procurement Notes

Verify the specific suffix (+) indicates RoHS compliance when sourcing. Confirm the operating frequency range aligns with system requirements, as performance varies across the 250 kHz to 400 MHz spectrum. Ensure the 5-SMD footprint matches the PCB layout constraints. Cross-reference datasheet electrical specifications against application needs to validate insertion loss and isolation characteristics.

Balun Selection Notes

Select this component for designs requiring a 50 Ohm balanced-to-unbalanced transformation within the VHF/UHF range. Consider the 0.3 dB typical insertion loss for low-loss signal paths. Evaluate the physical dimensions of the 5-SMD package against available board space. Compare against other TC1 series variants if different impedance ratios or frequency ranges are required for the specific application.

Balun Part Context

The TC1-42+ belongs to the TC1 series of audio and signal transformers manufactured by Mini-Circuits. This series spans a wide frequency range from 0.15 MHz to 4000 MHz, offering various impedance options including 50, 75, and 100 Ohms. These components are engineered for high-performance RF applications, providing reliable signal conversion and impedance matching in compact surface-mount formats.

Balun Replacement Considerations

Consult Mini-Circuits documentation for direct substitutes within the TC1 series that match the 50/50 Ohm specification and 250 kHz–400 MHz frequency range. Verify pin compatibility and electrical parameters before substituting.
