TCM3-1T+

Product Overview

Mini-Circuits TCM3-1T+ provides 1:3 transformer operation across 2 MHz to 500 MHz. The 1:3 ratio establishes the intended relationship between the 50 Ω system ports while performing balanced/unbalanced conversion. Confirmed selection data includes insertion loss of 2.0 dB maximum, return loss of 16.34 dB minimum, phase balance of 2°.

Core-and-wire construction gives this family broad low-frequency response while retaining useful RF bandwidth for IF, HF, VHF and UHF circuitry. The 1:3 impedance ratio strongly affects voltage and current transformation, so the ratio and winding orientation must remain unchanged in an approved BOM.

Quality & Sourcing

Antrex Electronics can support sourcing of TCM3-1T+ for production, repair and shortage requirements. Incoming inspection should compare the exact ordering code, operating band, impedance ratio, package style and winding configuration. Alternative approval should be based on the confirmed electrical limits and PCB footprint rather than on a similar family name.
