TC1-1X+

Product Overview

TC1-1X+ is a 1:1 Mini-Circuits transformer for 1.5 to 500 MHz, supplied in the AT1521 top-hat package. It is intended for 50 Ω circuits that need galvanic transformer coupling or conversion between a single-ended line and a balanced stage without changing the nominal impedance ratio.

The datasheet cites a 0.6 dB typical mid-band loss. Its bandwidth supports HF and VHF equipment as well as lower-UHF receiver or test paths. The X package and configuration C define the installed footprint, so replacement selection should distinguish this part from TC1-1+ and TC1-1G2+ even when the headline electrical range appears similar.

Quality & Sourcing

Antrex Electronics can help source TC1-1X+ for current production, maintenance and obsolete-component requirements. For substitution review, compare the operating band, impedance ratio, center tap where applicable, package style and PCB footprint; electrically related Mini-Circuits suffix variants are not always mechanically interchangeable.
