TC16-161TX+

Product Overview

TC16-161TX+ is a top-hat 1:16 transformer covering 600 kHz to 160 MHz. It is intended for circuits that need a large impedance step from a 50 Ω single-ended network to a high-impedance balanced port, while retaining transformer isolation across IF, HF and lower-VHF frequencies.

The AT1521 package is the defining difference from the AT224-1A and AT224-3 members of the TC16-161 family. That package distinction is important for board compatibility even though the ratio and frequency range are shared. A 1:16 transformer also produces a strong voltage/current transformation, so the surrounding termination and winding connection must follow the original circuit design.

Quality & Sourcing

Antrex Electronics can source TC16-161TX+ 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.
