TC16-161TG2+

Product Overview

TC16-161TG2+ is the AT224-3 version of Mini-Circuits’ 1:16 transformer for 600 kHz to 160 MHz. It connects a 50 Ω path to a high-impedance balanced load while also providing transformer isolation and balanced/unbalanced conversion.

The G2 package differentiates this part from TC16-161T+ and TC16-161TX+, which share the electrical ratio and band but use other mechanical constructions. In an exact BOM replacement, the AT224-3 land pattern and component height must therefore be retained. The high 1:16 ratio also makes load impedance and winding orientation more critical than with a unity-ratio balun.

Quality & Sourcing

Antrex Electronics can source TC16-161TG2+ for established RF and instrumentation BOMs. For these high-ratio or multi-winding transformers, approval should include winding topology, ratio, pin configuration, frequency response and exact case style because a visually similar unity-ratio balun will not reproduce the circuit behavior.
