TC1-1G2+

Product Overview

TC1-1G2+ is a 1:1 core-and-wire transformer for 1.5 to 500 MHz in Mini-Circuits’ AT224-3 package. It provides transformer isolation and balanced/unbalanced conversion while maintaining a 50 Ω nominal impedance on both sides, covering HF, VHF and a portion of the lower-UHF spectrum.

The G2 ordering code identifies the AT224-3 mechanical platform and configuration C. This matters for production sourcing because the electrical range overlaps TC1-1+ and TC1-1X+, but the package height, lead form and land pattern are different. In an RF layout, the balanced pair should leave the transformer with equal geometry to avoid adding phase or amplitude error not present in the component data.

Quality & Sourcing

Antrex Electronics can help source TC1-1G2+ 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.
